Question

Choose whether the following statement is True or False:
A non-defining adjective clause adds essential information about something or somebody, and completes the sentence in meaning.

• A. True
• B. False

Answer 1

The correct option is B False

An adjective clause is a group of words that contain a subject and a verb, and it functions as an adjective that modifies a noun or a pronoun. Adjective clauses usually begin with relative pronouns such as who, whom, whose or a relative adverb like when, where and so on.
A defining adjective clause gives essential information about the noun/pronoun that it modifies, without which the meaning of the sentence is incomplete.
A non-defining adjective clause merely gives extra information about the noun/pronoun which isn't important to the sentence.
For example:
'Janine, who has an amazing voice, is my mentor.'- Here the adjective clause 'who has an amazing voice' is non-defining (it only gives extra information) and is separated by commas.
'The person who has an amazing voice is my mentor.'- Here the adjective clause 'who has an amazing voice' defines the unknown 'person', as 'person' is a common noun and can refer to anybody.
Hence the statement is False; option B is correct and A is incorrect.
