Question

How many hole/holes does a normal drinking straw have?

A1

B2

C0

Select from the options above.

Correct Option: 1  

Explanation:
A straw mathematically speaking is a stretched donut. Since we can agree that a donut has one hole it must follow that a straw too has one hole. It does not matter that there are multiple entrances if it leads to only one cavity. Therefore a straw has only one hole.
