Q1  15
Q1 15

Question 1: She finally told her manager ___ she had been feeling overwhelmed at work.

Question 1 options
'that' is correct because it introduces a noun clause functioning as the direct object of 'told.' 'which,' 'who,' and 'what' do not correctly introduce reported statements about feelings in this context.
Q2 15

Question 2: ___ the scientist discovered in the lab surprised the entire research team.

Question 2 options
'What' is correct because it introduces a noun clause functioning as the subject of the sentence. 'Which,' 'That,' and 'Whether' cannot begin a subject noun clause in this context without a preceding noun to refer to.
Q3 15

Question 3: A noun clause can function as the subject of a sentence.

Question 3 options
True because noun clauses perform all the same grammatical roles as nouns, including acting as the subject of a sentence (e.g., 'What he said was surprising').
Q4 15

Question 4: Why is a noun clause used in the sentence: 'The committee discussed whether the budget should be increased'?

Question 4 options
'whether the budget should be increased' acts as the direct object of the verb 'discussed,' replacing a simple noun phrase with a whole clause. Noun clauses function as the direct object of a verb, not as an adverb, adjective modifier, or subject complement in this example.
Q5 15

Question 5: Arrange the words to make a correct sentence:

Question 5 options
  • why
  • was cancelled
  • Nobody knows
  • the project

Drag items or use arrows to arrange them in the correct order.

The correct order is 'Nobody knows why the project was cancelled' because the noun clause 'why the project was cancelled' functions as the direct object of 'knows,' using statement word order after the interrogative word 'why.'
Q6 15

Question 6: Which sentence uses a noun clause correctly?

Question 6 options
'I wonder whether she will accept the offer' is correct because the noun clause 'whether she will accept the offer' uses statement word order after 'whether.' The other options incorrectly use question word order inside the noun clause.
Q7 15

Question 7: Customer: 'Can you explain the delay?' Manager: 'I'll let you know ___ the shipment will arrive as soon as I hear back from the supplier.'

Question 7 options
'when' is correct because it introduces a noun clause functioning as the direct object of 'know,' indicating the time information that will be shared. 'although,' 'because,' and 'so that' introduce adverbial clauses, not noun clauses.
Q8 15

Question 8: Which sentence contains a noun clause rather than an adjective clause?

Question 8 options
'She appreciated what her mentor had taught her' contains a noun clause because 'what her mentor had taught her' functions as the direct object of 'appreciated.' In the other options, the clause modifies a noun, making it an adjective clause.
Q9 15

Question 9: Put the words in the correct order:

Question 9 options
  • is
  • The real issue
  • lacks clear leadership
  • that the team

Drag items or use arrows to arrange them in the correct order.

The correct order is 'The real issue is that the team lacks clear leadership' because the noun clause 'that the team lacks clear leadership' follows the linking verb 'is' and acts as a subject complement (predicative noun clause).
Q10 15

Question 10: After years of debate, the board finally agreed on ___.

Question 10 options
'what the new policy should include' is correct because it is a noun clause functioning as the object of the preposition 'on.' The other options are simple noun phrases or infinitive phrases, not noun clauses introduced by an interrogative word.
Q11 15

Question 11: Which statement about noun clauses is true?

Question 11 options
Noun clauses use statement word order (subject + verb), not question word order, even when introduced by question words like 'what' or 'why.' The other options incorrectly describe noun clause behavior.
Q12 15

Question 12: Rewrite using a noun clause: 'The cause of the accident is unknown.' → ___ caused the accident is still unknown.

Question 12 options
'What' is correct because it introduces a noun clause ('What caused the accident') that replaces the noun phrase 'The cause of the accident' as the subject of the sentence. 'That,' 'Which,' and 'Whether' do not correctly form this subject noun clause in this transformation.
Q13 15

Question 13: Match each sentence to the correct grammatical function of the noun clause.

Question 13 options
Whatever you decide will have major consequences.
Everyone knows that she is the most qualified candidate.
My biggest concern is whether we have enough funding.
The prize will go to whoever scores the highest.
Noun clause as object of a preposition
Noun clause as subject complement
Noun clause as direct object
Noun clause as subject

Select an item on the left, then tap its match on the right.

Noun clauses can serve as subjects, direct objects, indirect objects, objects of prepositions, or subject complements (predicatives) depending on their position and role in the sentence.
Q14 15

Question 14: The word 'where' always introduces a noun clause when it appears in a sentence.

Question 14 options
False because 'where' can introduce an adjective clause (e.g., 'The town where I grew up is small'), an adverbial clause, or a noun clause depending on its function. Its clause type is determined by the role it plays in the sentence, not by the word itself.
Q15 15

Question 15: Which sentence is more appropriate when formally reporting what a colleague said during a meeting?

Question 15 options
'She mentioned that the deadline had already been extended twice' is more appropriate in formal written English because it uses a 'that' noun clause for reported speech with correct backshifted tense. The other option uses direct speech, which is informal and less suitable for formal written reports.
