Answers Provided by NTA in revised answer key for Two Questions of #NEET2019 are controversial

1)#Biology : correct statement about Cornea (we believe 2 options are correct)
2)#Chemistry : work done by the gas (we believe -30 J is correct)

जहां बड़े कोचिंग संस्थानों ने अपने ही पढ़ाये हुए छात्रों को फिर एक बार मझधार में छोड़ दिया है और Result की खुशियां मना रहे हैं वहां कई बच्चे इंसाफ के लिए मदद मांग रहे हैं।
अब मैं यह फैसला आप लोगो पर छोड़ता हूँ..

[03/02/18]   Holi is the festival of colours, sharing joy, happiness and love.
Its a very common observation but unfortunately no one has voiced it out yet(as far as I know) that people throw water/coloured water to people walking on the streets in some sort of plastic packets. I am neither against throwing water nor in support of it, its the sole discretion of the people involved. What I want to point out is why use such plastic packets?
Because its cheaper?
Because its easier to fill in and throw?

Plastics aren't biodegradable, they harm the environment, they can get into the drainage system and block it and they can have numerous hazards,

Moreover when you throw your plastic filled joy of holi to people on the streets, and luckily if your aim is correct, believe me it is very unlucky for the person on which you have aimed at. These plastic bags when thrown from your rooftop gather enough kinetic energy to hurt and if it hits a sensitive area on the body it hurts a lot. Imagine your sister, mother or any other relative being hit with that. Please dont make your mazza,someone else's sazza.

Even if you want to celebrate Holi this way, use water balloon which I guess wont hurt
Why do we always choose saving money instead of saving our standards/culture/ethics?

It doesn't seem that we as a society are educated enough to think about this. Your education becomes worthless if you cant even think this much.

Do give it a thought...

I know a lot of people will agree to me on this and will surely be inspired to bring about a change but unfortunately as is the trend with social media posts that the inspiration lasts only for the duration for which you are online and the only initiative taken by the reader is liking and sharing the post(btw do that positively!).
But when it comes to take an action, the mind says, why me? everyone is doing it...why shall I pay more?
Remember one individual can make a difference... I hope everyone reading this post will become one such individual...
Lets pledge to have plastic free roads...yes you may take it as Swachh Bharat Abhiyaan as well...

Thanks for share the information as much as possible in order to spread awareness!

Have a happy and safe Holi!
