Can virus be created artificially/synthetically??

I marked yes.(All of the above)

Virus can't be, it's a pyq. 

Which year pyq? May be some latest research proves that it can be done. Normally answers to these types of questions have answers as All of the above. I too marked All.

@Aurang_mirasudar 2014 i guess, ditto repeat, virus is not in official answer key


It's 2013. There the option was "Viruses can be cultured in any synthetic medium"

Here, it just asks if it can be cultured, which it can be. Viral cultures are available

Viral culture - Wikipedia

Same statements are there in both papers. Upsc official keys in 2013 says virus can not be cultured in Synthetic medium. I too got this wrong. I marked All but it is wrong.

What is about lichens and mosses ?


Is it both lichens or mosses or only lichen ???

In this question, vajiram differs from Shankar and Vision. Actually Vision ias explanation based answer keys are nothing but elaborated answer keys of Shankar ias. No difference

Leaving the technical definitions aside,the framing of options also gives an insight into the possible right ans.

Stmt 3 is present individually and with two other stmts, which indicates that stmt 3 might be one of the correct statements.

So in this debate,1,2,3 seems to be more suitable ans.

Although I marked 2 and 4

At that point of time in exam hall, " ki ye question ke options hi wrong hain". Although i marked 2 and 4 and it is wrong.

There is no point in discussing answers now. The results will be out in next 15-20 days or may be earlier as mains is from 07th January only and this year's Prelims was a week late compared to last year. And nothing is going to be changed and Upsc does  give surprises in Science tech questions in their official answer keys.

@singlanitesh23707 check google map also.. Chenab meets indus directly. Even question was saying meeting of 3 other rivers. So in that case, ravi Sutlej and jhelum meets chenab only which meets indus directly


In Khullar , which is supposed to be  standard text book for Geography optional, it is clearly mentioned that Sutlej meets Indus after receiving combined water of three other rivers. 

I think people do prepare these stuffs from standard textbooks and not from websites, youtube videos etc. 

But if UPSC do gives Chenab as answer then only God can save future aspirants reading standard textbooks for this exam.

Post 2021 prelims different scenario from past years:

1. Aspirants not interested to disclose their marks.

2. Not interested to join any test series until results are declared.

3. Not interested to check different keys.

4. Not interested to discuss what is right or wrong.

5. Inflating marks by considering at least 60-70% disputed questions as right.

6. Institutes not interested to launch any test series until results.

7. Not enthusiastic to write answers until we clear prelims. 

A different scenario and environment this year 😐

But vajiram has already announced their mains test series, crash course,essay programs.And they do not refund the money in case aspirants want.I guess not many join their programs!

As regarding the question about " State", i still have doubt whether all states need to be Sovereign?As there are some Non sovereign states also if we search.

you r spot on,I strongly believe its b but none would accept it as coaching keys claim its a..Just wait for the result.it does not matter after that.

I too marked B option. This year's paper is very very tough.

@mounikamouni24_h944 it will be  chenab. 
Question basically has two parts. 
 3 other rivers meeting in main river and which joins the indus directly.
So sutlej can be negated from this as ravi and jhelum meet chenab, not sutlej. 
And in chenab all other three rivers meet. 
Don't just look at one part of question I.e. which meets indus directly. 


For this question, only thing can be said that it is very poorly worded and now it is upto UPSC , whether Chenab or Sutlej. And this one question may shatter the dreams of many as 2.66 marks are very important in this absurdly set paper checking random facts.

aisa lagta hai ki sirf ek hi question me dispute hai aur wo hai Cooker wala. Baaki lagbhag vision ka sahi hai keys with explanation( Indus hata ke)

Indus wale ka source Khullar me confirm Sutlej hai jo Shabbir sir ne bhi confirm kiya hai apne answer keys me. 

Baaki toh discussions ka koi end hi nahi hai.

@saurabher43267kisi ke pas chenab ka source hai kya... please share


I marked Sutlej as answer. Chenab ka kisi book me toh nahi hai.

Kya Khullar ko Authentic source maana jaa sakta hai Indus wale question me ? Sutlej mention kiya gaya hai book me. Length wise table me bhi sabse jyada length hai Sutlej ka according to Khullar.

Kisi NCERT ( Old/ New) me ye clearly mention nahi hai.

Hello guys .. alot of bloodshed has been happening so please dont beat me or cuss at me when I say this ..

so I spoke to one of my professors at DU (Political science department) about that polity question - safeguards of liberty in a liberal democracy and she definitely says the answer is Elected Government. She said though separation  of powers and rule of law are other ingredients but all of them wont be possible if a state does not have anelectedgovernmentat first (also the question specifically says liberal democracy) .. only then those things can be assured.  She also told me that with respect to such questions - read some philosophers (even if not from an optional background) like Aristotle, JS mill , Berlin etc  in free time and that may in general invoke some interest. Also despite my background in this subject , I haven’t taken PSIR optional so don’t think that I am in anyway advertising any optional .. just putting an end to this debate of “one of many interpretation “based questions.

I too marked Elected government option but ye wala galat hai. Mera 2 polity ke mistakes bahut bhaari padne wale hain. Doosra Article 32 mark kiya maine.

INDUS WATER TREATY CLEARLY SAYS PANJNAD RIVER IS INCLUDED IN CHENAB AND IT'S PANJNAD THAT TAKES WATER OF CHENAB AND SUTLEJ TO JOIN INDUS

Means Wrong information is given in D R Khullar Indian  geography book.

For the Indus river question, Upsc may give any answer Chenab or Sutlej based on its own interpretation. Even for the cooker wala question, it may give either 1& 3 or D ( All). 

I marked Sutlej and 1&3 in cooker.

Kisi na kisi ko nuksaan toh hoga hi bahut jyada.

Can we expect the results by Tuesday?

Pls see first part of question.

Three out of four given Rivers meet with 4th one..only Chenab fits in that criteria.

Sutlej may or may not drain directly, individually but Sutlej not taking waters from Jhelum and Ravi directly for sure. 

I guess this was the trap.


Although, I want Satluj to be correct for mine +2 but I'm hopeless.

Where it was written in the question that all 3  other tributaries should directly drain into the 4th one. The combined water of all three tributaries drain into Sutlej and it can be found in the book also. Also Sutlej by length is the longest tributary of Indus and this is a Fact.

Even if Upsc gives the answer Chenab or even Jhelum, we can't do anything.

The only advice I can give to people who are here is that to get a job after 2-3 failed attempts. You may discover new and beautiful areas of life, and then come back (or dont if you like there only). Your trauma will lessen.

If someone has prepared for years and attempted even 3-4 times, then he/ she will not get satisfaction anywhere and in any job. This exam has a very bad effect ( especially mental health effect) on any other future job options whether in private, psu or even state pcs jobs. It completely destroy the joy inside you in case of failure with attempt/ age exhausted.

Only final success with a rank gets you a peace.

I know three relatively easy questions in polity may ruin my chances: Right to property to only citizens ( wrong ), Article 32 marked ( wrong) and Elected govt. Marked ( wrong). 

Getting only 85 ( obc) considering doubtful questions wrong Sutlej ( wrong) , Pressure cooker (1&3) wrong, Smelting D ( wrong).
