Adjective clauses modify nouns or pronouns. Most adjective clauses are also known as relative clauses because they are usually introduced by the relative pronoun who, which, that, whose, or whom.
The relative pronoun is the subject or object of the clause it begins. Adjective clauses also usually appear immediately after the word that they modify.

5. Adjective/ Relative Clause
Rachel Carson (1907–1964) created quite a controversy with her widely read 1962 book, Silent Spring, which gave a sharp warning to the public.
However, a biology course that she took in her sophomore year at Pennsylvania College for Women led her in an entirely different direction.
Carson came up with the idea for Silent Spring after receiving a letter from a stranger in the state of Massachusetts who was disturbed by the effects of pesticides on her bird sanctuary.
The book's publishers underwrote a study to independently verify the statements that Carson had made about chlordane.
