Q1  15
Q1 15

Question 1: She stayed inside ___ it was raining heavily outside.

Question 1 options
'because' is correct because it introduces a subordinate adverbial clause showing reason. 'although' expresses contrast, 'unless' expresses a negative condition, and 'whenever' expresses repeated time.
Q2 15

Question 2: We will leave early ___ we can catch the first train.

Question 2 options
'so that' is correct because it introduces a subordinate clause of purpose, explaining why the action in the main clause is done. 'even though', 'as long as', and 'whereas' do not express purpose.
Q3 15

Question 3: A subordinate clause can stand alone as a complete sentence.

Question 3 options
False because a subordinate clause is a dependent clause — it needs a main clause to form a grammatically complete sentence. On its own, it is a sentence fragment.
Q4 15

Question 4: What is the main purpose of a subordinate clause in a sentence?

Question 4 options
'To add extra information to the main clause' is correct because subordinate clauses are dependent structures that provide additional detail such as reason, time, condition, or contrast. They do not form complete sentences alone or replace the main verb.
Q5 15

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

Question 5 options
  • if
  • You can borrow my book
  • tomorrow
  • you return it

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

The correct order is 'You can borrow my book if you return it tomorrow' because the main clause comes first, followed by the subordinate conditional clause introduced by 'if'.
Q6 15

Question 6: Which sentence uses a subordinate clause correctly?

Question 6 options
'She called me after she arrived at the hotel' is correct because 'after she arrived at the hotel' is a properly formed subordinate adverbial clause with a subject and verb. The other options either lack a subject in the dependent clause or misuse the subordinating conjunction.
Q7 15

Question 7: Teacher: 'How can I make this sentence more interesting: My brother plays football?' Student: 'You could add a subordinate clause.' Which option correctly adds a subordinate clause to the sentence?

Question 7 options
'My brother plays football even though he broke his leg last year' is correct because 'even though he broke his leg last year' is a subordinate clause with its own subject and verb, connected by a subordinating conjunction. The other options add phrases or fragments, not full subordinate clauses.
Q8 15

Question 8: Which sentence correctly uses a subordinate clause rather than a coordinate clause?

Question 8 options
'He went to bed because he was tired' is correct because 'because' is a subordinating conjunction that creates a dependent clause. 'and', 'but', and 'so' are coordinating conjunctions that join two independent clauses of equal rank.
Q9 15

Question 9: Put the words in the correct order:

Question 9 options
  • they
  • enjoyed
  • the trip
  • Although the weather was cold,

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

The correct order is 'Although the weather was cold, they enjoyed the trip' because a subordinate adverbial clause starting with 'although' can precede the main clause and must be followed by a comma.
Q10 15

Question 10: The manager will approve your request ___ you submit all the required documents by Friday.

Question 10 options
'provided that' is correct because it introduces a subordinate conditional clause showing the condition under which the main clause will happen. 'despite', 'besides', and 'instead of' cannot introduce a clause with a subject and finite verb in this structure.
Q11 15

Question 11: Which statement about subordinate clauses is true?

Question 11 options
'A subordinate clause must contain both a subject and a verb' is correct because, like all clauses, a subordinate clause requires a subject and a finite verb. It is introduced by a subordinating conjunction or relative pronoun but cannot stand alone as a sentence.
Q12 15

Question 12: Original: 'I will help you. You must ask politely.' Combine using a subordinate clause: 'I will help you ___.'

Question 12 options
'if you ask politely' is correct because it transforms the second independent sentence into a subordinate conditional clause using 'if'. The other options use conjunctions that change or distort the meaning of the original sentences.
Q13 15

Question 13: Match each sentence to the correct type of subordinate clause.

Question 13 options
She called me when she got home.
He stayed home because he felt ill.
You can go out if you finish your homework.
This is the teacher who helped me most.
Subordinate adverbial clause of reason
Subordinate relative clause
Subordinate adverbial clause of time
Subordinate adverbial clause of condition

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

Subordinate clauses are classified by their function: adverbial clauses of time use conjunctions like 'when/after', adverbial clauses of reason use 'because/since', adverbial clauses of condition use 'if/unless', and relative clauses use 'who/which/that' to describe nouns.
Q14 15

Question 14: A subordinate clause can sometimes appear at the beginning of a sentence, before the main clause.

Question 14 options
True because subordinate adverbial clauses are flexible and can precede the main clause (e.g. 'When I arrived, she left.'). When the subordinate clause comes first, it is typically followed by a comma before the main clause.
Q15 15

Question 15: Which sentence most naturally expresses a contrast using a subordinate clause?

Question 15 options
'He kept working although he was exhausted' is the most natural choice because 'although' is specifically a subordinating conjunction used to introduce a concessive subordinate clause expressing contrast. 'however' is a conjunctive adverb, not a subordinating conjunction, and cannot join clauses in the same way.
