Appreciate if anyone can advise on the following question :


GROUP A : CAT, WHALE, MONKEY
GROUP B : GOOSE , PENGUIN , OWL

The animals are grouped according to

1- what they eat
2- where they live
3 - how they move
4- their body covering

Anyone can explain why is 4 is the answer

[rocklee]

Let me try this.


Animals in group A belong to the group of Mammals. Mammals are generally covered with fur.

Aminals in group B belong to the group of Birds. Birds are generally covered with feathers.

Make sense?

[starlight1968sg]

Yes, the ans is option 4 ie group according to their body covering.


OT: a bat is a mammal though it looks like a bird.

Thanks for your reply ! But, only cat and monkey got fur . Whale does not have fur

whale, dolphin etc are mammals. Their females have milk for their babies.
A shark is not a mammal but a fish.

Q:How does saliva help in the process of digestion?
A: It breaks down carbohydrates into simple sugar.

This is a 1 mark question but the above answer gets only half mark. Can anyone advise what is wrong with the answer. Thanks.
