What is the name of an eleven-sided polygon?
Correct answer: Hendecagon

Republic of China
Imagine saying "All three is correct". Obviously, for me, that is wrong to choose that option.
It's like saying "What is a chicken"
Then options are
Beef
Milk
Vegetables
All of those/All of them/All of them are used
Then you guys chose "All of those"
