Can someone please explain why B is wrong? I am still confused. #help

It has been a few months... any chance we get to see this happen?

Agreed

I agree, I also did not choose the correct answer because of the "only if."

#help I am wondering the same.

I am having trouble understanding why some of the examples, like 3.1 and 3.2 among others, are not arguments and am struggling with support. For example, for 3.1, here was my thought process:

'Human communication is a universal phenomenon that has existed across different civilizations over time. Linguists have conducted many comparative analyses of traditional languages from various regions and eras.'

Here, I thought the conclusion was 'Human communication is a universal phenomenon that has existed across different civilizations over time.' I used the 'why' and thought, well, because 'Linguists have conducted many comparative analyses of traditional languages from various regions and eras.'

Is there a way we can get a bit more explanation on why this is wrong and how we can identify where there is no support in an argument? Thank you!
