Ans 14:

Class : Class 9
Mathamagician, we should not say anyone fool. Please keep in mind

Ans 15:

Class : Class 7
the correct answer is D as in B there is no mention on what X is

Ans 16:

Class : Class 5
it is 'b'

Ans 17:

Class : Class 10
Organism X is actually emu, because it has wings AND feathers. So correct answer is D.Answer B however is wrong, as it tells emus ONLY have feathers. Answer C is wrong as organism X can be any bird, even penguins. And answer A is also wrong as bats don't have feathers and ostriches have wings too.

Ans 18:

Class : Class 4

Ans 19:

Class : Class 10
Fe facts:1) Ostriches have wings, though it is not used for flying.2) Bats do not have feathers. They have hairs like other mammals.3) Emu has wings and again not used for flying.4) A penguin has feathers.5) Almost all birds have wings and feathers.So, option D is the only one that seems right.

Answer is b

Ans 24:

Class : Class 3
Bats have wings and no feathers. Ostriches and Emus have both feathers and wings, but they can’t fly mainly due to their huge size. Penguins have feathers and flippers (not wings). “A” is incorrect as bats doesn’t have feathers. “B” is incorrect as penguins doesn’t have wings. “C” is incorrect as there are birds that has both feathers and wings. “D” is the correct answer

b

Ans 27:

Class : Class 6
D is only correct as in option B they have given that Z can be emu but emu has both wings and feathers and it is a flightless bird
