Question 5

The lady explaining how to go through the question stated that "Quantifier don't have contrapositives". I wanted to know if she was just applying that to this specific passage or in general, in any passage.

Hi @lgriffon22069,

Thanks for the question! Yes, that’s a general rule about quantifiers. Quantifiers in general do not have contrapositives, in any passage you come across. You cannot go from

A —most—> B

to

~B —most—> ~A

Though you can make a some statement

B <—some—> A

And that’s a general rule.

Hope this helps! Feel free to ask any other questions that you might have.
