Could you explain the grammar from a native speaker’s perspective?
I’m studying English in Japan, but there’s a question I just can’t seem to understand.
Choose the most appropriate answer to fill in the blank.
Evelyn: I think I saw Raphael last night at the library.
Mateo : That can't be right. He ( ) to Paraguay.
1 has been
2 has gone
3 had been
4 had gone
I thought 4 was the correct answer, but the answer key says 2.I thought this question was ambiguous because there isn’t enough context, and that either answer could be possible.
Could you explain why 4 is incorrect?
