B1 Relative Clauses (Who / Which / That) Grammar Test 1 (15 Questions) – IELTS, TOEFL, YDS Practice
Practice relative clauses with who, which, and that in this B1 grammar test. Includes 15 multiple-choice questions and detailed explanations for IELTS, TOEFL, and YDS.
Relative clauses are an essential part of English grammar, especially at the B1 level, where learners begin to form more complex and detailed sentences. These clauses help us give additional information about a noun by using relative pronouns such as “who,” “which,” and “that.” Understanding how and when to use these pronouns correctly is key to improving both writing and speaking skills.
In exams such as IELTS, TOEFL, and YDS, relative clauses are commonly tested because they reflect a learner’s ability to connect ideas and provide clear descriptions. “Who” is generally used for people, “which” for things, and “that” can be used for both in defining clauses. Choosing the correct relative pronoun depends on the noun being described and the structure of the sentence.
This test is designed to give you practical, exam-style experience with relative clauses. Each question focuses on choosing the correct relative pronoun in context. The explanations section at the end will help you understand the rules and improve your accuracy in using relative clauses.
