Ans 3:

Class :
It is certainly B as ashes of any organic matter makes soil fertile.

Ans 4:

Class : Class 8
B IS THE CORRECT ANSWER AS BURNING OF WASTE CROPS AFTER HARVESTING OF GRAINS IS STANDARD METHOD OF INCREASING SOIL FERTILITY

Ans 5:

Class : Class 7
the answer is B.

Ans 6:

Class : Class 9
Ash is an organic matter so the answer should be B

Class : Class 9
I think the answer is B

Ans 8:

Class : Class 7
Harry?! What a fake! Harr potter is an adult!

Ans 9:

Class : Class 8
WHAT! B is correct, not A. The answer is B, NOT A!

Ans 10:

Class :
I think the answer should be b as after a forest gets destroyed by a forest fire ,new trees will grow as the remain of the trees will decompose and make the sol fertile.

Ans 11:

Class : Class 7
BBBB IS THE ANSWER

Ans 12:

Class : Class 7
i think the answer should be B because the statement 'New trees will grow quickly to replace the burnt ones as the ash of the burnt trees will make the soil more fertile' is also true

Ans 13:

Class :
Come on Snigdha! The CORRECT ANSWER IS (B)! Ash makes soil fertile 'cause it's organic , dude! How will trees not grow?(P.S.- please don't think about Ash in Pokemon. Please, don't)🤦‍♂️🤦‍♂️

I agree with Ishan as trees cannot grow very quickly...But I did B at my first attempt

Ans 21:

Class : Class 9
B is the correct answer

Ans 22:

Class : Class 7

Ans 23:

Class : Class 7
THe AntwerpThe answer is (A) because if forest fire occurs there will not be any trees and soil erosion can happen and All the ashes including soil may erode and then how can it make the soil fertile

Ans 24:

Class : Class 10
I agree ,B is the correct answer

Ans 25:

Class : Class 5
The question and choices given are a bit tricky. The correct answer is A because the language of (iv) is deceptive and says "new trees will grow quickly to replace the burnt ones". You have to understand that "new trees" won't grow quickly, you can only sow small plants not trees.

Ans 26:

Class : Class 7
B is the answer!

Ans 27:

Why C is incorrect answer? During Summer month at noon there will be shadow exactly under feet.

Ans 3:

Class : Class 8
I suppose that option'B' is the correct answer. If my thinkings are wrong, then please kindly make me understand with a reason i understand in simple words. If my answer is correct then please, please, please comment on it. My goal here is not to give long lectures, but to find the correct answer to this question.

Ans 4:

Class : Class 6
The answer should be C.

Ans 5:

Class : Class 9
It should be (b) because (c) shows that there is no shadow at noon, however even in summer, there is a small shadow at noon. Therefore the answer should be (b).

Ans 6:

Class : Class 6
I think it's option B, as at noon we do have a shadow although it's very small, it's not like there's no shadow at all. If my answer is wrong, kindly rectify

Ans 7:

Class : Class 9
yes c is correct kindly rectify
