360 degrees LED street light. https://www.ledimeister.ee/tronix-led-post-top-latern-360-e27-street-light
I think in this question, positive aspects of LED lamp vis-a-vis sodium lamp are asked and ergo any statement mentioning a negative aspect of LED lamp wouldn't be true (LED lamp has longer life, not monochromatic unlike sodium lamp). I think this question has been asked related to PM Atal Jyoti Yojana. Likewise, a Q on solar water pump was asked in 2020 related to PM Kusum Yojana and it showcased positive aspects of solar power pumps. Having said that, it's the UPSC which will decide the official answer. https://vikaspedia.in/energy/policy-support/renewable-energy-1/atal-jyoti-yojana
@Aurang_mirasudar 1, 3 and 4 isn’t an option, bro. 😄
@Aurang_mirasudar I think UPSC will consider stove as correct. Microwave or not seems like nitpicking to me. Let’s see.
@Aurang_mirasudar No false hope, bro. People were nitpicking over Ozone in 2019 Prelims too. We all know answer to that Q. Nitpicking doesn't work in UPSC. Anyway, only time will tell the answer. IMHO, it should be D. :)
@Aurang_mirasudar Some clarity on Right to City Q.
@prachimalik1121311 In my opinion, answer here will be D. The more important word here is "may" and not "lethal", and the most important word is "concern". Try to negate the CO statement, which is kind of absurd saying there is NO possibility at all that CO can escape in the environment given that it is a known hazard for copper smelting plant workers. Lethal doesn't necessarily mean a big amount. All the best.
@gOdFr33d Chenab without an iota of doubt.
@GOT8 I have seen it bro. Don't bother if you've not marked Chenab. I just posted what I think will be the answer. Feel free to disagree as the official answer will be known only next year. I wish you all the best! :)
@5HT The words "concern" and "may" are more important in this Q. Most importantly, nitpicking never works in UPSC papers. One has to think like a generalist while attempting such Qs. Negating the first statement, in fact, is highly improbable.
@monisha27 It’s good.
@bhuvanamalar1015412 This Q should be dropped.
If the cutoff stays around 90, me qualifying for Mains feels like walking a thin wire like Philippe Petit. Hopefully, in the end, my fate is the same as his. :) All the best, everyone!@rawhull How much has IASBaba predicted?
@peterparker You posting a song about Jhelum reminded me of this fantastic track I heard long back.

@balwintejas Could you please post the Telegram link of the group?
@prachimalik1121311 Which institute is this?
@sushil_21 Also, the PYQ statement has the word “any”. Had it been impossible to culture it in a synthetic medium, the statement would have simply been “Virus can be cultured in a synthetic medium” and still be wrong. Plus, there’s the word “artificial” in 2021 Q. Let’s see what the official answer is.
@prachimalik1121311 I wonder why people believe these institutes’ keys are sacrosanct. Vision IAS didn’t get 5 Qs correct in 2019, imagine the scenario in 2021! Shankar IAS got 7 Qs wrong in 2019! I remember Vision IAS got a Q on Buland Darwaza’s building material (which is red sandstone) incorrect in 2018. I had marked it D and almost every institute that year gave the answer as A. Always remember, UPSC always has the most general and broadest interpretations as correct answer; the one which is most aligned with common sense. As an administrator, is CO accidentally leaking inside/outside the plant a concern? For sure!
@Negan The"best" definition of State is B. It is the most comprehensive amongst all options. Also, it does include sovereignty in it, ergo holding true to the overly-emphasised Montevideo Convention's criteria of a State in almost all coaching institutes' key, which I think is in particular context of international law. I 'd mark it B even I were to attempt the paper today.
