Prologue

• [T25] series contains 25 Mock MCQ for UPSC IAS/IPS Civil Service exam aspirants.
• This particular article, gives you practice questions from Environment, Agriculture and Geography subjects.
• Timelimit: 30 minutes.
• 2 Marks for correct answer; -0.66 marks for wrong answer.

Environment: Basic definitions

Q. NPP [Net Primary Productivity] is highest for (CAPF-2017)

1. tropical forests
2. swamps
3. reefs
4. woodland and shrubland

HINT:
Technically, Gross primary productivity (GPP) is the total amount of solar energy captured and stored in the form of organic substances by the green plants. Net primary productivity is the amount of organic substances left in the plant after its own metabolism i.e. GPP = NPP + plant respiration.
In crude terms, NPP is the rate at which producer biomass (=usually plant) is created. So, even by Guessmastergiri^TM possible to arrive at answer that tropical forests have more trees/plants born every year, so it’ll have highest NPP. But next time, UPSC examiner might ask ascending descending order of NPP, so let’s prepare that as well. The descending order of NPP is:

1. Open Ocean (42)
2. Tropical forest (37)
3. Savannah (13)
4. Cultivated Land (9)
5. Temperatrate forest (6-8)
6. Woodland and Shrubland (6)
7. Swamp (4)
8. Estuaries (2.1)
9. Reef (1.6)
10. Desert (1.6)
11. Tundra (1.1). Ref: From this google book

Q. The ecological niche of an organism relates to (CAPF-2017)

1. specific habitat of the organism
2. symbiotic relationship with other organisms
3. diverse occurrence of a species under different conditions
4. its interaction with all other organisms

HINT:

• Habitat is the physical environment in which an organism lives (it corresponds to address of an organism). So, #A is not the right definition of Niche.
• Niche refers to the functional position of a species in its habitat. So among the B, C and D, which one is closely related to that term?

Q. Study of a single species and the environmental factors in its habitat is called (CAPF-2017)

1. Genecology
2. Synecology
3. Autecology
4. Ethology

HINT: We must also know the meaning of the wrong options, lest they get asked in future UPSC!

• Genecology is the study of the gene frequency of a species in relation to its population distribution
• Synecology is a branch of ecology that deals with the structure, development, and distribution of ecological communities.
• Ethology is a branch of zoology concerned with the study of animal behavior.
• Autecology is the subdivision of ecology which studies individual organisms or species

Q. Free swimming macroscopic animals in an aquatic environment are referred to as (CAPF-2017)

1. Plankton
2. Periphyton
3. Benthos
4. Nekton

HINT: It’s not sufficient to know the right answer, we must also know the meaning of the wrong options, lest they get asked in future UPSC!

• Nekton = aggregate of actively swimming animals in a body of water ranging from microscopic organisms to whales.
• Benthos = Organisms (plants and animals) that live at or near the bottom of a sea.
• Periphyton = is a complex mixture of algae, cyanobacteria etc that is attached to submerged surfaces in most aquatic ecosystems.

Environment: Pollution

Q. Presence of ozone in the atmosphere is important because it absorbs (CAPF-2017)

1. ultraviolet-A and ultraviolet-B radiations
2. ultraviolet-B radiations only
3. infrared-B radiations only
4. outgoing ultraviolet-B radiations and incoming ultraviolet-A radiations

HINT: Ultra violate light (UV) has three subtypes based on their wavelength. Shorter the wavelength=more dangerous for body.

1. UVA wavelength longest among 3 Majority of UV radiation coming to earth, is of this type. UV-A is hardly absorbed at all by the Earth’s atmosphere, and it reaches its surface with nearly full intensity.
2. UVB wavelength medium. It cannot penetrate beyond skin layer. Hence does all its damage to skin itself e.g. tanning, burning, skin cancer. UV-B radiation is mostly absorbed by the ozone layer.
3. UVC shortest wavelength among 3, hence extremely hazardous to DNA, and Artificial UVC lights often used as a sterilizing agent to kill germs in food/pharma industries. UV-C is completely absorbed by the ozone layer, which is fortunate since humans have no natural defense against this kind of radiation. [Ref: University of Michigan]

107) Which one of the following statements about air pollution caused by diesel engines is correct? (CAPF-2017)

1. it produces large quantity of carbon monoxide at lower and high temperatures
2. it produces large quantity of nitrogen oxides at lower and high temperatures
3. it produces large quantity of carbon monoxide at lower temperature and nitrogen oxides at high temperature
4. it produces large quantity of nitrogen oxides at lower temperature and carbon monoxide at high temperature

HINT: Seems UPSC examiner mistook that CAPF as a recruit exam for environmental mechanical engineers. Anyhows, when diesel engine is at lower temperature, there is rise in CO, whereas at high temperature there is rise in NOx. [Ref: google books ]

Q. Which one of the following is a major effect of long term consumption of drinking water containing little [less than 0.5 ppm] or no fluoride ? (CAPF-2017)

1. cavity of tooth
2. Erosion of nail
3. Deformation of bone
4. Mottling of tooth

HINT: NCERT Class12 Chemistry Ch2, first para: 1 part per million (ppm) of fluoride ions in water prevents tooth decay, while 1.5 ppm causes the tooth to become mottled and high concentrations of fluoride ions can be poisonous. So, if Floride<0.5ppm, then ‘tooth decay’ will not be prevented. Which option has a closest synonym for this?

Q. Which of the following diseases are caused by the consumption of water contaminated by mercury and nitrate ? (CAPF-2017)

1. Minamata disease and Osteoporosis
2. Osteoporosis and Blue Baby Syndrome
3. Minamata disease and Blue Baby Syndrome
4. Osteoporosis and Minamata disease

HINT: This one is easy, directly given in NIOS Environment PDF.

• Drinking water with Nitrate level exceeds 10 ppm causes methaemoglobinaemia particularly in bottle fed infants who are very sensitive to this pollutant. Due to reduced carrying capacity for oxygen the babies gradually acquire a blue tinge and hence the name – “Blue Baby disease”.
• Japan, mass mercury poisoning (Minamata disease) was observed in 1960s, caused by eating fish from Minamata Bay which were contaminated with methyl mercury.
• Osteoporosis is the softening of bones due to calcium deficiency. Calcium absorption is dependent on availability of Vitamin D. Women, post menopause are prone to osteoporosis because Estrogen, the female hormone mobilises calcium and sends it to bones. In the absence of estrogen, bones tend to crack and break.

Q. Which one of the following diseases is caused by Cadmium pollution? (CAPF-2017)

1. Minamata
2. Itai-Itai
3. Fluorosis
4. Blue baby syndrome

HINT: This too was asked in the same UPSC- CAPF – 2017 paper, so if you know the correct answer to previous question, you can easily deduce the right answer for this one!

Environment: Flora-Fauna

Q. Which of the following are the necessary conditions for the growth of coral reefs ? (CAPF-2017)

1. Photic conditions
2. Clean and sediment free water
3. low level of salinity
4. Tropical sea water with temperature of 20C to 21C.

Select the correct answer using the code given below :

1. 1 , 2 and 4 only
2. 2 and 4 only
3. 1 and 3 only
4. 1, 2 , 3 and 4

HINT: UPSC examiner does test the patience of a candidate! No single book source gives verbatim answer for all four statements, because even though ShankarIAS page36 and GCL p81 have covered the topic in detailed mannre, they’ve not used the specific word ‘photic’ condition, or exact level of salinity.

• Corals need high light. Most reef-building species are restricted to the euphotic / photic zone i.e. the region in the ocean where light penetrates to a depth of approximately 70 meters. So, 1 is right.
• Corals need clean, clear (=sediment free). So, 2 is right.
• Corals also require very saline (salty) water ranging from 32 to 42 parts per thousand. [Ref US Gov Website] So #3 is wrong.
• Corals can’t survive below the 20 degree temperature, or near cold currents. Hence, their areal distribution of corals is confined to tropical and sub-tropical zones. So, #4 is right.
• Eliminate accordingly, and more importantly, do read back the correct statements in the question. Otherwise, you’ll not gain maximum knowledge and proficiency in solving multi-statement MCQs.

Q. Which of the following statements about the equatorial region are correct ? (CAPF-2017)

1. It is a megathermal region
2. It is a sclerophyll region
3. It is a region of high development
4. It is a region of aerial streamlets

Select the correct answer using the code given below:

1. 1 and 4
2. 1 and 2 only
3. 2, 3 and 4
4. 1, 2 and 3

HINT: Another ‘patience – testing’ MCQ by UPSC examiner because these concepts are known but ‘technical-terms’ are not known to ordinary aspirants.

• Equatorial regions are sparsly populated. Excessive heat and humidity, jungle, inspects and pests affect the development. [GCL p119-120] NCERT also marks equatorial region as ‘area of subsistaence gahtering’ so they couldn’t be high development (otherwise juntaa should not be doing commerical cultivation and going for NEET-coaching classes) [Ref: Class12 Fundamentals of Human Geo. Ch5 map 5.3]
• So #3 is wrong, this eliminates C and D. Both A and B options, statement “1” is right, so it ought to be right.
• Megathermal climates are split into two subsets 1) equatorial- with no variation in temperature throughought the year and 2) tropical- with seasonal veriation. So, #1 is indeed right.

Since we’ve only option A or B left: This mean correct answer boils down to whether statement #2 is right or #4 is right?

• In equaotrial forest, most of the rains is intercepted by forest canopy and thus reaches ground surface slowly in the form of aerial streamlets through leaves, branches and stems of trees and thus there is maximum infiltration of rainwater. Meaning #4 is right. [Ref: Physical Geography: Biogeography By K. Bharatdwaj.]
• Sclerophyll region: Low trees and plants with small-hard-thick-leather leaves which remain evergreen. Canopy coverage is 25% so, it’s mostly an ‘open forest’. They’re closely associated with Mediterranean region. So #2 is wrong- Sclerophyll region not associated with equator.

Q. Consider the following statements : (CAPF-2017)

1. Areas where rainfall exceeds 250 cm
2. Annual temperature 25C – 27C
3. Average humidity exceeds 75%
4. Trees do not shed the leaves

To which one of the following types of vegetation does the above represent ?

1. Tropical wet evergreen
2. Tropical semi evergreen
3. Tropical moist deciduous
4. Tropical dry evergreen

HINT: NCERT 11 India Physical Environment chapter 5:

• It can’t be D, because Tropical deciduous = 70-100cm rainfall, whereas here the area has >250 cm rainfall. The chapter mentions characteristics of tropical evergreen forest, and it matches with above description. But whether it’s tropical wet or moist or dry, that internal differntiation is unavailble. Which means UPSC examiner has smartened up his act, he had not asked this MCQ directly from NCERT.
• Google books reveal that:
• Tropical Wet Evergreen = rainfall >250 cm and >77% humidity
• Tropical Semi Evergreen = rainfall 100-250cms; and 75% humidity
• Tropical Dry Evergreen = rainfall about 100 cms, and 75% humidity. Now you can pick the closest option.

Possible to solve through Guessmastergirl^TM also: deciduous= shed leaves so it can’t be C. Since avg humidity >75% so the words “semi evergreen” and “dry evergreen” don’t fit the vibe. Hence it has to be “A”.

Q. Match List I with List II and select the correct answer using the code given below the Lists : (CAPF-2017)

List I [Shrubs Vegetation] Chaparrals Maquis Fynbos Malle scrubs

List II [Region] North America Southern Europe South Africa Australia

Code: a / b / c / d

1. 1 2 3 4
2. 1 3 2 4
3. 4 3 2 1
4. 4 2 3 1

HINT: UPSC examiner has lifted this verbatim from Physical Geography: Biogeography By K. Bharadwaj page 128:

• Maquis / Garrigue : Europe
• Chaparral: California (=North America)
• Mallee: Australia
• Fynbos / Fymbosch: South Africa

लेकिन इतना टेक्नीकल कौन तैयार करता है!?

Q. Which one of the following tiger reserves of India has ‘Bhoorsingh the Barasingha’ as its official mascot ? (CAPF-2017)

1. Nameri tiger reserve
2. Ranthambhore tiger reserve
3. Panna tiger reserve
4. Kanha tiger reserve

HINT:

• Panna @Madhya Pradesh
• Ranthambhore @Rajasthan
• Nameri @Assam
• Kanha (Madhya Pradesh) has become the first tiger reserve in India to officially introduce a mascot — Bhoorsingh the Barasingha (swamp deer), in 2017-March. [Ref: HindustanTimes]

Q. Match List I with List II and select the correct answer using the code given below the List : (CAPF-2017)

List I [Bird Sanctuary] Sultanpur Kulik Nawabganj Attiveri

List II [State] West Bengal Haryana Uttar Pradesh Karnataka

Code: A B C D

1. 2 1 3 4
2. 2 3 1 4
3. 4 3 1 2
4. 4 1 3 2

HINT: Sultanpur @Haryana (A:2),Nawabganj @UP (C:3), Attiveri @Karnataka (D:4).

Q. Statement I : Chameleon changes its skin colour to match with the colour of the surroundings. Statement II : The skin of chameleon emits light of the colour of the surrounding through fluorescence. (CAPF-2017)

1. Both the statements are individually true and Statement II is the correct explanation of Statement I.
2. Both the statements are individually true but Statement II is NOT the correct explanation of Statement I
3. Statement I is true but Statement II is false.
4. Statement I is false but Statement II is true

HINT: First statement is commonly known GK fact. Second statement is not right. While recently, some researchers found florescence in the ‘bones’ of chameleon, but the actual color changing mechanism is in skin.

• When chameleon changes color, its nanocrystals / pigment cells beneath the skin expand or shrink. Accordingly the red, yellow and other color pigments are modified which leads to change in color. So that’s not fluorescenes.
• Fluorescence is the property whereby a molecule emits light at a specific wavelength when irradiated by light of a shorter wavelength (usually UV ray or X-ray). Fluorescence ceases as soon as the exciting source is removed.

Agriculture

Q1) Statement I : Plantation farming has mostly been practiced in humid tropics. Statement II : The soil of humid tropic is highly fertile (CAPF-2017)

1. Both the statements are individually true and Statement II is the correct explanation of Statement I.
2. Both the statements are individually true but Statement II is NOT the correct explanation of Statement I
3. Statement I is true but Statement II is false.
4. Statement I is false but Statement II is true

HINT:

• Plantation agriculture was introduced by the Europeans in colonies situated in the tropics. Some of the important plantation crops are tea, coffee, cocoa, rubber, cotton, oil palm, sugarcane, bananas and pineapples. [NCERT Class 12 Human Geography]
• Tropical equatorial biomes’ soil is acidic and poor in nutrients. [NCERT 11 Fundamental Physical page 130]. and Just to crosscheck from google: “Oxisols and Ultisols together cover about 63% of the total land area of the humid tropics. These soils are highly acidic (pH 4 to 5), often contain toxic concentrations of Al and Mn, and are usually deficient in essential plant nutrients (e.g., N. P. Ca). [Ref: United Nations University project Website]

Q. Which one of the following is NOT correct about organic farming? (CAPF-2017)

1. It does not use genetically modified seeds.
2. Synthetic pesticides or fertilizers are not used.
3. It uses minimal crop rotation.
4. It uses ecologically protective practices.

HINT: Organic farming is a type of agriculture or farming which avoids the use of synthetic fertilizers, pesticides, growth regulators, and livestock feed additives. Organic farming systems rely on crop rotation, crop residues, animal manures, legumes, green manure, off-farm organic wastes and biofertilizers, mechanical cultivation, mineral bearing rocks. [NIOS Environment p116]

Geography: Physical

Q. Which one of the following instruments is used for measuring moisture content of air? (CAPF-2017)

1. Hydrometer
2. Hygrometer
3. Hypsometer
4. Pycnometer

HINT:

1. Hydrometer: A measuring instrument for determining the specific gravity of a liquid or solid
2. Hygrometer: comprises of wet and dry bulb thermometer, for measuring the relative humidity of the atmosphere [GCL p98]
3. Hypsometer: An altimeter that uses the boiling point of water to determine land elevation
4. Pycnometer: a standard flask for measuring and comparing the densities of liquids

Q. Consider the following statements about ‘Ring of Fire’. (CAPF-2017)

1. It is also known as circum-Pacific belt of volcanoes
2. It is an active seismic zone
3. It is a zone of divergent plate margin

Select the correct answer using the code given below :

1. 1 only
2. 1 and 2 only
3. 2 and 3 only
4. 1, 2 and 3

HINT:

• First statement is a commonly known GK-fact, and given in both GCL (page25) as well as NIOS Geography (page25)
• Observe नकशा-the Map given in NCERT Class11 ch.4: You can see that Pacific region has convergent boundries. So, #3 is wrong. This eliminates C and D.

Observe Fig.4.2 from the same NCERT Chapter. You can see that atleast some portion of the ring of fire, is in the deep earthquake zones. Additionally, GCL page25’s Map puts that entire zone in “major earthquake belt”. That means second statement is also right.

Q. Which one of the following statements about the Himalayas is NOT correct ? (CAPF-2017)

1. They are young fold mountains
2. They have geosynclinal rocks
3. Himalayan frontal faults [HFF] separates Himalaya from Tibet
4. Indus and Sutlej rivers form antecedent drainage in Himalaya

HINT: Here UPSC examiner has gone beyond the NCERTs by dwelling into geosynclines and HFF. Refer to Majid Hussain’s Geography of India (7th Ed) Ch2 and Ch3 हिंदी में भी उपलब्ध]

• Himalayas in Asia, the Alps in Europe, the Rockies in North America and the Andes in South America are the most prominent fold mountains of the world, Since these mountain ranges were formed during the most recent mountain building period, they are known as young fold mountains. So #1 is right.
• Himalayas have geosynclinal origin. So, #2 is also right.
• Main Central Thrust (MCT) separates Greater Himalaya and Lesser Himalaya. Main Boundry Thrust (MBT) separates Lesser Himalaya and Shiwaliks. Himalayan Front ault (HFF) separates Shiwaliks from Northern Plains.
• Antecedent (inconsequent) rivers are the rivers that existed before upheaval of Himalaya, and they’ve cut their courses southwards by making gorges in the mountains. example: Indus, Satluj, Ganges, Tista and Bramhaputra.
• Consequent rivers are the rivers that follow general direction of slope. Most of the peninsular rivers are consequent rivers.

Q. Which one of the following is NOT a favorable condition for occurrence of a thunderstorm ? (CAPF-2017)

1. conditional and convective instability
2. Adequate supply of moisture in the lower atmosphere
3. Advection of cold dry air in the lower troposphere and warm moist air in the upper troposphere
4. A synoptic situation of low level convergence and upper level divergence

HINT: UPSC examiner seems to have mistaken CAPF exam for Geography Optional MCQ paper of the Pre-CSAT era. इतनी पी.एच.डी. कौन करता है जब एल-नीनो-मानसून मिकेनिजम भी मुश्किल से याद रहे पाता है! Anyways, let’s try: NCERT Class11 FUNDAMENTALS OF PHYSICAL GEOGRAPHY:

• A thunderstorm is a cumulonimbus cloud producing thunder and lightening. (p96)
• A thunderstorm is characterised by intense updraft of rising warm air, which causes the clouds to grow bigger and rise to greater height. (p96)
• Transfer of heat through horizontal movement of air is called advection. (p80)
• यानि की Option C’s word “advection of cold air and advection of warm moist air”- it’s not giving the right ‘vibe’, because warm air has to “rise”, then “horizontal” movement (=advection) seems irrelevant.

Geography: Map / Location based

Q. Match List I with List II and select the correct answer using the code given below the Lists : (CAPF-2017)

List I: [Hydro power project ] Maithon project Salal project Rana Pratap Sagar project Tehri project

Code: A B C D

1. 2 1 4 3
2. 2 4 1 3
3. 3 1 4 2
4. 3 4 1 2

HINT: bolo UPSC examiner seems to have lifted this verbatim from NIOS Geography PDF’s Table. Salal:Chenab @J&K (B:4), Tehri: Bhagirathi @Uttarakhand (D:2).

Q. Match List I with List II and select the correct answer using the code given below the Lists : (CAPF-2017)

Codes: A|B|C|D

1. 1 2 4 3
2. 3 2 4 1
3. 3 4 2 1
4. 1 4 2 3

HINT:

• (C2) Chromite oxide occurs in Sukinda Valley in Odisha. India Yearbook 2018 ch. 19 on industry | हिंदी में भी उपलब्ध]
• (B4) There are 3 important gold fields in India: Kolar @Mysore (KAR), Hutti @Raichur (KAR) and Ramgiri @Andhra. [Majid Hussain Page 7.16]
• (A3) Rajasthan is leading producer of lead, it’s mined in Udaipur’s Zawar… Zinc is found in association with lead and silver. [Majid Hussain Page 7.12]

Human Geography & Guessmastergiri ^TM

Let’s try to solve both the following MCQs with guessmastergiri and see whether it leads to any NET-GAIN in the exam?

Q. Which of the following statements related to tribes in India are correct ? (CAPF-2017)

1. Tharu tribes are found in Uttar Pradesh and Uttarakhand
2. Irula, Chenchu and Sumali tribes are found in Kerala
3. Garasia tribes are found in Goa
4. Gaddi tribes are nomadic herdrs of Jammu and Kashmir and Himachal Pradesh

Select the correct answer using the code given below :

1. 1 and 3 only
2. 2 and 4 only
3. 1, 2 and 4 only
4. 1 , 2, 3 and 4

HINT: Seems UPSC examiner wanted to see who has encyclopedic knowledge about Tribe locations in CAPF-2017 paper.

• Gaddi are noted for ‘transhumance’ in J&K and HP. i.e. When the higher reaches of the mountains become too cold, they come back to the lower valleys. Their annual movement is always along some fixed routes and generally their grazing areas are also fixed. This type of altitudinal migration is called trans-humance. Their name is mentioned multiple times in NCERT Class11: India Physical. Knowing this, the UPSC examiner has deliberately repeated statement #4 in three choices (B, C, D). Thus this ‘ordinary knowledge’ doesn’t help in arriving at the “pre-gambling” stage for Guessmasters^TM (i.e. atleast two options must be eliminating) Meaning, UPSC examiner has set the answer choices meticulously.
• Since B, C and D – all three have Statement#2: so we must accept that Irula, Chenchu and Sumali tribes are INDEED found in Kerala.
• Garasia are associated with Gujarat-Rajasthan. So, Goa is far away from their home regions. Statement#3 wrong, now we’ve only two options B or C. [Ref: Majid Hussain Page 13.18].
• Now since only two options left, you’ve the ripe opportunity to apply Guessmastergiri^TM that Tharu sounds like Southern surname so it can’t be UP/Uttarakhand that means #1 is wrong, and therefore B is the answer. But Then you’re wrong, because Tharu are indeed associated with Uttar Pradesh and Uttarakhand [Ref: Majid Hussain Page 13.18].

So, In above MCQ, Guessmastergiri leads to loss of -0.66 marks. But it’s all about law of average, so let’s try one more time.

Q. As per Census 2011, which one of the following is the correct descending order of States in India is respect of sex ratio [female per thousand of males] ? (CAPF-2017)

1. West Bengal > Madhya Pradesh > Uttarakhand > Jammu and Kashmir
2. Madhya Pradesh > West Bengal > Jammu and Kashmir > Uttarakhand
3. Uttarakhand > West Bengal > Madhya Pradesh > Jammu and Kashmir
4. West Bengal > Uttarkhand > Madhya Pradesh > Jammu and Kashmir

HINT: Again, UPSC examiner is testing the knowledge of aspirants by not putting easy to guesstimate states like Kerala vs Haryana. Let’s try Guessmastergiri^TM here:

• Area / Population wise- Larger states usually have lower sex ratio than smaller states on account of more urbanization / migration, education, sonography-abortion. [Barring the exceptions like Punjab / Haryana.]
• Often EPW and TheHindu columnists praise that Muslim community has lower female infanticide. Although we don’t have census figure at hand about Muslim population in any state but it’s frequently mentioned in ZeeNEW how Mamta-di’s appeasement policies on Dusshera / Mohram so, W.Bengal ought to have more significant presence of Muslims than Madhya Pradesh which is a BJP stronghold. यानि की तुक्केबाजी के नियमानुसार प.बंगाल का लिंग-अनुपात मध्य प्रदेश से बहेतर होना ही चाहिए.
• From the logic so far, we can “guess” that [W.Bengal > Madhya Pradesh]. Only A, C and D fit this pattern. and in all three options, J&K is at bottom, so it makes our guessmastergiri task easier [otherwise, it could have created confusion, since both J&K and W.Bengal have significant Muslim population.]
• Now, in A, C and D options, If our “smallerstate=better-sex ratio” logic is right then, Uttarakhand ought to be better than [W.Bengal < Madhya Pradesh] because it’s a smaller state. Only C fits this pattern. In both options J&K is at last so it’s immaterial. so “C” should e the answer by Guessmastegiri.

now let’s crosscheck with official Census-2011 sex ratio figures given in Table 1.6 given in the ch.1 of IYB:

• Uttarakhand 963
• W.Bengal 950
• Madhya Pradesh 931
• J&K 889

Epilogue

• Had you applied Guessmastergiri ^TM in both the Human geography questions then your Net-gain was -0.66 marks in Tribes MCQ PLUS 2 marks in Sex ratio MCQ = +1.34 marks.
• Although this is not truly Guessmastergiri per se, because you needed to know many background factoids to eliminate atleast two wrong options.
• तो मित्रों, बिना पढ़े तो प्रीलिम पास नही कर सकते, सिर्फ भोलेभाले बच्चो को clickbait videos & articles से बेवकूफ बना सकते है.
