Question 5
4 / -1

All ducks are birds.
Some birds fly, and noreptiles are birds.
A snake is a reptile.
If theabove are true, which of the following would also be true?

A
Snakes do not fly

B
No snakes are ducks

C
All ducks fly

D
Some birds are snakes

Solution

• All ducks are birds, which means every duck belongs to the category of birds.

• Some birds fly, but this does not mean that all birds or all ducks can fly.

• No reptiles are birds, which means reptiles and birds are completely separate groups.

• A snake is a reptile, so snakes cannot belong to the category of birds.

Since all ducks are birds and no reptiles are birds, snakes cannot be ducks.

Option A is incorrect because the statements do not provide information about whether snakes can fly.

Option C is incorrect because only some birds fly, not necessarily all ducks.

Option D is incorrect because snakes are reptiles, and no reptiles are birds.

Therefore, no snakes are ducks is the only conclusion that logically follows.

The correct answer is: Option B: No snakes are ducks
