Questions: Dependent Clauses: Adverb, Adjective, and Noun Clauses

Question 1

Which of the following is a complete sentence?

• A. Because the train was late.
• B. Although she had studied all night.
• C. The package that arrived this morning.
• D. When the alarm goes off, wake me up.

Answer: (D)

Option D is a complex sentence: 'when the alarm goes off' is a dependent clause, and 'wake me up' is an independent clause — together they form a complete sentence. Options A and B begin with subordinating conjunctions ('because,' 'although') but have no attached independent clause, making them subordinate clause fragments. Option C has a relative clause ('that arrived this morning') modifying 'package,' but there's no verb for the main clause — it's a noun phrase, not a sentence.

Question 2

In the sentence 'The scientist who discovered the cure won the prize,' what function does the clause 'who discovered the cure' perform?

• A. It is an adverb clause telling when the scientist won
• B. It is a noun clause acting as the subject of the sentence
• C. It is an adjective clause modifying 'scientist'
• D. It is an independent clause joined to the main clause

Answer: (C)

The clause 'who discovered the cure' is an adjective (relative) clause: it modifies the noun 'scientist,' telling us *which* scientist. The relative pronoun 'who' introduces it and refers back to 'scientist.' It answers the noun-modifying question 'which one?' — the same job a single adjective would do. It is not adverbial (it doesn't modify the verb 'won'), not nominal (it doesn't act as subject or object), and not independent (it can't stand alone).

Question 3

A dependent clause contains both a subject and a verb but cannot stand alone as a complete sentence.

• T. True
• F. False

Answer: True

This is exactly what defines a dependent (subordinate) clause. The subject and verb are present, but the subordinating word at the beginning — a conjunction like 'because' or 'although,' or a relative pronoun like 'who' or 'that' — signals incompleteness. 'Because she studied' has a subject (she) and a verb (studied), but 'because' tells the reader a result is still coming. Without an attached independent clause, it is a fragment.

Question 4

'What she said surprised everyone' is a fragment because it begins with 'what,' which signals a question.

• T. True
• F. False

Answer: False

This is a complete sentence, not a fragment. 'What she said' is a noun clause functioning as the subject of the verb 'surprised.' 'What' here is a relative pronoun introducing a nominal clause, not an interrogative word forming a question. The test: does the whole word group have a subject and a main verb? Yes — the subject is the clause 'what she said,' and the verb is 'surprised.' Noun clauses can occupy the subject position just like ordinary nouns.

Question 5

What determines whether a dependent clause is classified as an adverb clause, an adjective clause, or a noun clause? Explain using an example of each.

Model answer: The type is determined by the clause's grammatical function, not by how it looks. An adverb clause modifies a verb (e.g., 'Because she studied, she passed' — answers 'why'). An adjective clause modifies a noun (e.g., 'The book that I borrowed was good' — tells which book). A noun clause acts as a noun — subject, object, or complement (e.g., 'What he said upset me' — the clause is the subject).

Function-based classification is the core skill. The same subordinating word can signal different clause types depending on how the clause is used. Ask: what question does this clause answer? If it answers when/where/why/how about a verb, it's adverbial. If it specifies or describes a noun, it's adjectival. If it occupies a noun slot (subject, object), it's nominal.
