Soru: Choose the sentence that correctly uses a relative clause to combine the following two sentences:
Sentence 1: The book was very interesting.
Sentence 2: I read it last week.
A) The book which I read last week was very interesting.
B) The book who I read last week was very interesting.
C) The book that I read last week, was very interesting.
D) The book, that I read last week, was very interesting.
Çözüm: The correct answer is A. 'Which' is the appropriate relative pronoun to use for objects (like 'book'). 'Who' is used for people. Option C and D are incorrect because they use commas unnecessarily with restrictive relative clauses.
