2. I went to where I and my ex-girlfriend had been last weekend.
3. Suddenly I get nausea Whenever I see his face. (Nausea = nausea / vomiting willing).
b). Clause is preceded by the words specific question (ie who, Whom, Whose + noun) can also function as an adjective clause. In this case, the question is actually a relative pronoun. Well, do not be too confused by the term. Important that you understand the pattern / structure of the sentence. But, if you are curious, please read the adjective clauses topic.

Adjective clause (ie in the form of an adjective clause) describes noun, and relative pronounnya (ie who, that, ect.) In Indonesian means “the”.
