this is what makes me choose �� who��
1. I looked up in the dictionary:
who= the person that,
whoever= ->no matter who since the result will be the same. (and in the sentence it does matter who)
->the person or people who.
* Who and whoever have these similar meanings as you can see "the person that" and "the person or people who" So this kind of makes me doubt.
2. We are trying to use an INDIRECT OBJECT PRONOUN in that sentence, the most correct GRAMATICALLY should be ��whom�� but since the preposition is at the end...it seems they are testing if we know the other way to use THAT INDIRECT OBEJCT when there is a preposition. And the other way is �" who.... with"
If we put "whoever" it really makes sense for me as well. I don�t think is incorrect. But I think according to what they are asking me and the sense of the sentence mixed with the meaning given in the dictionary of both. WHO still be the answer for me.
I respect your opinion ZORA... You are a native teacher, you seem to have more experience so yeap you make me doubt of my answer.
Both are fine for me WHO and WHOEVER but if i HAVE to choose one I�dstill choose WHO (following my own knowledge and perception)
