Sir,the answer for the question no 6 should be O+, because when the blood group of the parents are AB and O; the child's blood group may be A or B. and since the boy is adopted and it is given in the question that " the blood group of the three sons are A+,B+,O+".
The Answer is 'a'.

Q.35 is slightly tricky! max density at 4 deg C explains why ice floats on water; after that it is about ice being a poor conductor due to which the water below does not freeze.

Sailaja said on June 13th, 2011

Hi Sir,

Could you let me know what could be the cut off marks?
Is it that paper 1 and paper 2 are evaluated individually?

-Sailaja

brkanth said on June 13th, 2011

Sir, Answer for 17th question is missing

Sailaja said on June 13th, 2011

Question Number 2 regarding Aspartame:

I found this from Wiki:

Aspartame, an artificial sweetener, is approximately 200 times sweeter than sucrose, or table sugar. Due to this property, even though aspartame produces four kilocalories of energy per gram when metabolized, the quantity of aspartame needed to produce a sweet taste is so small that its caloric contribution is negligible.

So correct answer should be (d), I suppose.

for the El nino La nina question - why is statement 2 true - LA NINA increases the monsoon ..its good for monsoon so 2 is false ....1 is true ..El nino is warm ocean current ; La Nina is Cold current ..

vg_220 said on June 13th, 2011

Question No 39 asks - Which of the statements is "not" true?

Your explanation suggests that option D was true. Hence correct answer has to be some other option. :)

Excellent work by the way!

test said on June 13th, 2011

cut off of 90/200 in paper I is going to kill many. The focus was on env/biodiversity etc. I guess the cutoff would be above 60/200 . I dont believe myself saying that, however based on my canvassing across many people the avg seems to be 33-38% correct. Would like to know your views.

Anil said on June 13th, 2011

Sir i think i'l get in the range 190-200.. prob is my score in paper 1 is around 60 and in paper 2 it's upto 140.. ther'll be individual cut offs for each paper o they'll take the whole ?? also what r my chances of clearing ??

For Qn 52
The growth rate of percapita income has not risen steadily. It sometimes increased by 6%, then by 4% then by 8% and so on... the increase in percapita income is there. But the increase in growth rate of percapita income is absent over the lst five years in a steady fashion. Answer should be D.

aby said on June 13th, 2011

Question 60- you seem to have overlooked the deepening part. The present max size of ships for malacca straight is called malacca max. the water depth is only 25m here. The deepening of this straight will allow largeer ships to travel through this canal and hence reduce the time they require to go around the sumatra island. so this is one way of reducing travel time and difficulty. Apparently, this is one of the concerns of india govt as well as other players who want to reduce travel time between east india and east asia. Both options are hence correct. kra canal is also bein g mooted btw. GREAT WORK GOING ON INTHIS BLOG!!

Qn 72
radio waves have very long wavelength. that is why they get reflected(refracted actually) off the ionosphere facilitating communication. HF radio cannot use ionosphere, only long wave radios can! hence the second statement is correct

aby said on June 13th, 2011

Qn 95- if there are no trans fats, it means the fats are saturated fats. which come from animals. so statement 2 is wrong

also a question on "growth rate in percapita income has steadily increased over past 5 years"..

its wrong...

page 2 indian ecomomic survey 2010-11

amount of percapita is increasing 27123 rs(2005-06). 31198rs(2006-07), 35820rs(07-08)....

but "Growth Rate" is decreaing for first 3 yrs and then increased for next to years..

Raju Qureshi said on June 14th, 2011

Sir, For Ques.72, Statement 2, i.e., Radio waves have very long wavelength is right. So I feel Option 2 is correct.

Because among the classification of EM waves, Radio waves have longest wavelength. And high energy incidence of waves on ionosphere will make the wave pass through ionosphere.

Sir,

22nd question, the second statement "They use a variety of inorganic materials as substrates." gives an impression that organic substrates are not used at all. But in a paper published by National Institute of Science Communication and Information Resources (NISCAIR) (Issue Date: Oct-2010) its mentioned "Microbial fuel cells (MFCs) employ microbes to generate electricity from biochemical energy produced during metabolism of organic substrates."

This is the best and most comprehensive answer key that I have seen so far..Thanks a ton to all those whose efforts went in to create it :-)

It also gave me some confidence..According to it, I have around 52 right, 45 wrong (Net score: 74 on 200). I should be scoring between 150-160 in Paper-2. Will appreciate if you could comment on my chances of making it to the Mains?

Also, I would like to mention that I am working with a corporate post my MBA from a reputed institute, and haven't prepared anything for the Mains as yet. But do have that little bit of excitement about clearing the IAS :) Do you think it would be possible for me to prepare well for the Mains through the weekend classes at some IAS prep institute? (I intend to take up "Management" as Optional 1, and perhaps "Mathematics" as optional 2.. any suggestions for the institute, or on preparation?? (should I take the risk of resigning from my present job?).. I know that's a lot of questions, but would be really grateful if any kind soul could give his/her opinion on the above..

PS: Please reply here itself..
-> I am an Engineer, and have 2 years of IT experience..graduated from a top B-school this year, and working with a corporate in a decent role (~13-15 lakhs per annum).. but still, that 'satisfaction' is missing.. hope you understand..

Q20 : -> All human diseases are genetic ?? May be some doctor can throw some light on this question.

Amit said on June 14th, 2011

Q35 :- > Good analysis.
Supporting facts::

But why doesn't the entire body of water freeze, like a giant, lake-sized ice-cube? Generally, all liquids expand on heating, but water is an exception to this rule. If water is heated, its volume gradually decreases. (This decrease in volume continues till the temperature rises to 4 °C.) At temperatures over 4 °C water starts expanding. It then keeps expanding with the further rise in temperature, till finally at 100 °C it turns into steam.

In other words, at 4 °C, water has the least volume (occupies the least amount of space) and maximum density (is at its heaviest). This irregular expansion of water is called anomalous expansion. This anomalous expansion plays an important role by only freezing the upper layer in lakes and rivers.

During winter months in colder countries the outside or atmospheric temperature is very low - it drops to below freezing - and the upper layers of water in the lakes and ponds start cooling. When the temperature of the surface layers falls to 4 °C, the water body acquires maximum density and sinks down. The water that sinks down displaces water below, and the lower layers of water simultaneously rise up. This also gets cooled to 4 °C and again sinks down.

When the temperature of the water body finally goes below 4 °C, the density or heaviness of water decreases and as a result water does not sink down. The surface water finally freezes at 0 °C while the lower part still remains at 4 °C. The light frozen layer of ice floats on top.

Ice does not allow heat to pass through it easily, so the freezing of the waters below is a very slow process. At depths below 30 metres, temperatures are cold and stable, but food is scarce. As a result animals have adapted to this situation by growing more slowly.

Ram said on June 14th, 2011

Sir, the answer for question no 66 is C i.e, both 2 and 3. Carbon dioxide trapped in polar ice caps is one of the major source for estimating the level of increased carbon dioxide in atmosphere over years. This is how scientists are calculating the difference/increase in greenhouse gases over years. It is called ICE CORE DATA.

Ram said on June 14th, 2011

With regard to question 90, statement C fits very well into the question and the purpose of the current Mega Food Parks. How can a government miss such important aspect as providing eco-friendly and environmental friendly technologies for future Food Parks when the government is so much worried about sustainable development.

vi17june said on June 15th, 2011

Sir, please post the answers of Q. 17, 98, 99 & 100, bcoz you are the only reliable source to us......

Ram said on June 15th, 2011

Sir, with respect to question number 35, I agree with your explanation. But some other sources are of the view that it is due to highest density of water at 4 C. I think the density concept only explains why ice floats on water, it does not explain why the water below it remains a liquid.

So, Answer to Q.37 should be D.

Answer of Q.39 should be (a). I am quoting some lines from Bipin Chandra -
"...the element of spontaneity in the movement of 1942 was certainly larger than in the earlier movements..." (page-468, last paragraph)
"...in a way, the degree of spontaneity and popular initiative that was actually exercised had been sanctioned by the leadership itself..." (page-469, 1st paragraph)
"...But many of those, including many staunch Gandhians, who used 'violent means' in 1942 felt that the peculiar circumstances warranted their use..." (page-469, last paragraph)
"...Gandhiji refused to condemn the violence of the people because he saw it as a reaction to the much bigger violence of the state..." (page-470, 1st paragraph)

sanjeev03022 said on June 16th, 2011

I didn't understand your logic behind Q.25. Option 2 is outrightly rejected as if you reduce the export subsidy, your export of good will get reduced and thus import of foreign currency will get reduced. This may widen the Current Account Deficit. Also, CAD is reduced by promoting FDIs and FIIs and devaluing the currency. So, answer should be (d). It is clearly mentioned here: http://en.wikipedia.org/wiki/Current_account#Reducing_current_account_deficits

regarding Q43
Drip irrigation, also known as trickle irrigation or microirrigation, is an irrigation method which saves water and fertilizer by allowing water to drip slowly to the roots of plants, either onto the soil surface or directly onto the root zone, through a network of valves, pipes, tubing, and emitters. Drip irrigation has been used since ancient times when buried clay pots were filled with water, which would gradually seep into the grass. Modern drip irrigation began its development in Afghanistan in 1866 when researchers began experimenting with irrigation using clay pipe to create combination irrigation and drainage systems.[citation needed] In 1913, E.B. House at Colorado State Universitysucceeded in applying water to the root zone of plants without raising the water table. http://en.wikipedia.org/wiki/Drip_irrigation

Q95

Animal-based fats were once the only trans fats consumed, but by far the largest amount of trans fat consumed today is created by the processed food industry as a side effect of partially hydrogenating unsaturated plant fats (generally vegetable oils). These partially hydrogenated fats have displaced natural solid fats and liquid oils in many areas, the most notable ones being in the fast food, snack food, fried food, and baked goods industries. They can only be made by cooking with a very high heat, beyond the temperatures possible in a household kitchen.
http://en.wikipedia.org/wiki/Trans_fat

it implies animal fat is also trans fat

aarti said on June 16th, 2011

Hi All,
There i always the criteria of qualifying marks,which will be kept low in paper-I as it was tough.........earlier also those who got 45 out of 150 were writing mains, for paper -II it may be high say 40 %, and further there may be a condition that one must score >160 out of 400 as the total.
i.e. one with >60 in P-I and>40 in P-II, and total >180 is safe

KISHAN PRASAD said on June 18th, 2011

Having gone through the paper, I strongly feel one who gets 60+ in paper I and 120+ in Paper II should make it. In the case of Software Engineer who participated in the blog, I suggest he take a full one year break, prepare well in the Optional subjects and other papers before he quits his job. For this time he could continue his job till main exams and try his luck if he could manage preparing in this short 3 months time such a vast syllabus. Perhaps the gentleman does not have full depth of understanding the agony put in by several students who even after qualifying in the mains not getting selected. Appearing for Civil Services Examination is like perpetual preparation keep attempting until one gets through for final, provided you have moral, physical and reasonable financial support for a period of close to one-and-half to two years. considering two years of working with a packet of 15L pa, the candidate could take the risk after writing the main exam.
All the best to all the participants.
