Q1  15
Q1 15

Question 1: I wanted to go to the park, ___ it started to rain heavily.

Question 1 options
'but' is correct because it is a coordinating conjunction that joins two independent clauses showing contrast. 'Although' and 'because' introduce dependent clauses, and 'however' requires a semicolon or starts a new sentence, not a comma-joined compound sentence.
Q2 15

Question 2: She finished her homework, ___ she went out to meet her friends.

Question 2 options
'so' is correct because it is a coordinating conjunction showing result, linking two independent clauses in a compound sentence. 'Therefore', 'thus', and 'consequently' are conjunctive adverbs and cannot join two clauses with only a comma.
Q3 15

Question 3: In a compound sentence, both clauses must be independent clauses that can stand alone as complete sentences.

Question 3 options
True because a compound sentence is formed by joining two or more independent clauses. If one clause cannot stand alone, the sentence is complex, not compound.
Q4 15

Question 4: Which situation correctly shows the purpose of using a compound sentence?

Question 4 options
'Connecting two related complete ideas with equal importance' is correct because compound sentences join independent clauses that are related and grammatically equal. The other options describe complex sentences, simple sentences, or run-on errors.
Q5 15

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

Question 5 options
  • we decided
  • The weather was cold,
  • yet
  • to go hiking

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

The correct order is 'The weather was cold, yet we decided to go hiking' because a coordinating conjunction (yet) with a preceding comma joins two independent clauses in a compound sentence.
Q6 15

Question 6: Which sentence is a correctly formed compound sentence?

Question 6 options
'Tom likes coffee, but Lisa prefers tea' is correct because it joins two independent clauses with a comma and the coordinating conjunction 'but'. The other options either use a subordinating conjunction, miss the comma, or contain a dependent clause.
Q7 15

Question 7: Student A: 'How can I show that two ideas are equally important and closely related?' Student B: 'You should ___.'

Question 7 options
'join them as a compound sentence using a coordinating conjunction' is correct because compound sentences express two equally important, related independent clauses. The other options describe complex sentences, simple sentences, or lists.
Q8 15

Question 8: Which sentence is a compound sentence rather than a complex sentence?

Question 8 options
'Maria cooked dinner, and David set the table' is correct because both clauses are independent and joined by the coordinating conjunction 'and'. The other options use subordinating conjunctions (when, because, although) which create complex sentences with dependent clauses.
Q9 15

Question 9: Put the words in the correct order:

Question 9 options
  • we can wait
  • until morning
  • We can leave now,
  • or

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

The correct order is 'We can leave now, or we can wait until morning' because a coordinating conjunction (or) preceded by a comma connects two independent clauses to form a compound sentence.
Q10 15

Question 10: My brother plays the guitar, ___ he has never performed on stage.

Question 10 options
'yet' is correct because it is a coordinating conjunction expressing contrast between two independent clauses, fitting the meaning that despite playing guitar, he has not performed. 'So' implies result, 'for' implies reason, and 'nor' requires a negative structure.
Q11 15

Question 11: Which statement about compound sentences is true?

Question 11 options
A semicolon can replace a coordinating conjunction and comma between two independent clauses in a compound sentence. A compound sentence never contains a dependent clause, it can have more than two clauses, and a comma alone without a conjunction creates a comma splice error.
Q12 15

Question 12: Rewrite as a compound sentence using a semicolon: 'She studied hard. She passed the exam easily.' → She studied hard; ___.

Question 12 options
'she passed the exam easily' is correct because when using a semicolon to join two independent clauses in a compound sentence, the second clause follows directly as a complete independent clause without a conjunction. The other options incorrectly add conjunctions or subordinators.
Q13 15

Question 13: Match each sentence to the correct grammar label.

Question 13 options
I called her, but she didn't answer.
He was tired, so he went to bed early.
We can take the bus, or we can walk home.
She loves painting, and her sister loves sculpture.
Compound sentence showing choice
Compound sentence showing result
Compound sentence showing contrast
Compound sentence showing addition

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

Compound sentences use coordinating conjunctions (and, but, or, so, yet, for, nor) or semicolons to join independent clauses. Each conjunction signals a specific relationship: addition (and), contrast (but), choice (or), result (so).
Q14 15

Question 14: When two independent clauses in a compound sentence are joined by a coordinating conjunction, a comma is always required before the conjunction, even in very short clauses.

Question 14 options
False because in informal writing or with very short, closely related clauses (e.g. 'She laughed and he smiled'), the comma is sometimes omitted. The comma before the coordinating conjunction is standard but not absolutely required for short compound sentences.
Q15 15

Question 15: Which sentence best expresses a strong contrast between two ideas while keeping both ideas equally prominent?

Question 15 options
'He is very talented, yet he refuses to practise' is best because the coordinating conjunction 'yet' in a compound sentence places equal grammatical weight on both contrasting ideas. 'Although' creates a complex sentence where one idea is subordinated, and the other options do not express contrast.
