Soru: Choose the correct relative clause to complete the sentence: "The book ______ I borrowed from the library is very interesting."
A) which
B) who
C) whose
D) whom
Çözüm: The correct answer is A) which. 'Which' is used to refer to things. Since 'the book' is a thing, 'which' is the appropriate relative pronoun to use. 'Who' is used for people, 'whose' indicates possession, and 'whom' is used for people when they are the object of a verb or preposition.
