@KingSlayer23 Magnetite particles are produced when there is friction between 2 ferrite metal surfaces, which causes wear and tear. In case of brakes and engine, it is true. Also, in case of power plants, there particles are released due to burning of coal with such impurities. However, in a Microwave oven and Telephone line, there are no friction causing moving parts and there is no burning. Hence, microwave and telephone lines are not a correct statements

@prachimalik1121311 Vision key is not accurate at all. Many questions are wrong in their key ( satluj, right to city, moringa (3,4,5 statements are right, moringa is deciduous)). Arcot wala question saaf saaf wikipedia ki first line sey uthaya haithe Nawabs of the Carnatic (also referred to as the Nawabs of Arcot) were the nawabs who ruled the Carnatic region of South India between about 1690 and 1855. The Carnatic was a dependency of Hyderabad Deccan, and was under the legal purview of the Nizam of Hyderabad, until their demise

Just an insight won't CO emission in copper smelting plant relates to coal being used as an energy medium to run the whole process

Carbon monoxide is a by-product of carbon burning. It simply is produced by insufficient supply of air. Further, in many kinds of smelting carbon dioxide is produced by further oxidation of carbon monoxide

Last year was scoring 104-106.66 (waiting in on the official score. IFoS result awaited). Wrote Mains.

This year, 94 - 96.67 (from Shankar, Vision, Forum)

And if upsc wanted, it could have made an option of fridge instead of microwave. Microwave is there so there is a good chance that they think it is the answer because microwave is such an odd choice to put

upsc deletes or awards bonus to all in case of controversial questions ??

Upsc me Controversial questions delete nahi hote bhai. These questions are controversial for us and not for upsc. Unhone jiska jo ans dia chup chap vo manna hi pdega. 

Agr translation me kuch blunder hua (like last year cdm ko ncm bana dia tha hindi me) tab hi chances hai ki ques del ho bt vo bhi upsc ki discretion pr depend krta hai.

Prev yrs ke pprs dkh lo har saal controversial questions hote hai bt kabhi kuch del nahi hua. 2020 ka bhi sb speculations hi hai abtk,jbtk key nahi aati tbtk kuch bol nahi skte.

Ye sb game state psc me hota hai jaha koi ek source leke jao toh vo log maan lete hai aur sbko marks de dete hai.

And someone can tell about why astronomical distances are measured in light years?

Why are many people getting lower scores than last year despite it apparently being an easier paper than 2020?

Also, was CSAT tougher than last year? I know that people were better prepared this year because of last year's failures in CSAT. Still any chance of it reducing the cutoff?

Ya fir dil behlane ke liye ghalib khayal achha hai...

I am telling again


only pressure cooker answer isnt decided..rest all are fine ..dnt waste time here



only variation from coaching keys will be right to city(23), magnetite (124) and pressure cooker (no idea)

@Admgenalanezh bhai ye article dobara padho.. it is describing the process of magnetite formation using the microwave as energy source than conventional sources, because it is energy efficient, not that it produces magnetite psrticles
