-
Q1What type of sentence is this: 'The cat slept on the sofa.'
Answer: D. Simple sentence
This is a simple sentence because it has one subject (The cat) and one action (slept). It tells one complete idea.
-
Q2Choose the simple sentence.
Answer: A. John and Mary went to the park.
This is a simple sentence because it expresses one complete thought. Even though it has two people (John and Mary), they are doing the action together. Other options like 'John went to the park, but Mary stayed home' are made of two separate ideas joined by words like 'but'.
-
Q3Complete the simple sentence: 'The students ___ and studied for the test.'
Answer: B. read
We need a past tense verb to match 'studied.' 'The students read and studied' is a single idea where the students do two actions.
-
Q4Identify the error in this sentence: 'The big dog he barked at the stranger.'
Answer: D. The redundant pronoun 'he'
The subject 'The big dog' is already complete and clear. Adding 'he' immediately after creates a double subject, which is a grammatical error. The correct sentence is 'The big dog barked at the stranger.'
-
Q5Which sentence is a simple sentence?
Answer: B. She likes coffee.
This sentence has only one subject (She) and one action (likes). It is a single, complete thought. The other options combine two different ideas using words like 'and', 'but', or 'so'.
-
Q6Complete the simple sentence: 'My brother ___ his bike in the park.'
Answer: B. rides
'Rides' is the correct action word for the subject 'My brother.' Words like 'riding' would need another word like 'is' to be correct.
-
Q7What type of sentence is: 'Tom and Sarah cooked dinner.'
Answer: D. Simple sentence
This is a simple sentence. Even though there are two people (Tom and Sarah), they are doing one main action together (cooked dinner).
-
Q8Identify the error: 'The teacher she explained the lesson.'
Answer: B. The redundant pronoun 'she'
We already know the subject is 'The teacher.' Adding 'she' right after it repeats the subject, which is a mistake.
-
Q9Which sentence is simple?
Answer: D. He walked to school and back.
This is a simple sentence because it tells us about one person doing one main trip. The other options join two separate thoughts using words like 'but', 'and', or 'so'.
-
Q10Complete the simple sentence: '___ played soccer all afternoon.'
Answer: D. The children
We just need one clear subject. 'The children' is correct. Using 'The children, they' repeats the subject twice, which is a common mistake.
-
Q11Identify the simple sentence.
Answer: A. The sun shines brightly.
This sentence has one subject (The sun) and one action (shines). The other choices join two different ideas using commas and words like 'but' or 'so'.
-
Q12Which sentence is punctuated correctly?
Answer: D. They sang and danced.
When one subject does two things (sang and danced), you do not need a comma between the actions.
-
Q13What is the subject of this simple sentence: 'The large, brown dog barked.'
Answer: C. The large, brown dog
The subject includes the main noun ('dog') and all the words that describe it ('The large, brown').
-
Q14Choose the simple sentence.
Answer: C. We cleaned the house.
This is one complete thought with no joining words like 'but' or 'so' connecting it to another sentence.
-
Q15Which sentence contains a punctuation error?
Answer: B. I want to go but I am tired.
When you join two full sentences with the word 'but,' you must put a comma before it. 'I want to go but I am tired' is missing that comma.
-
Q16What type of sentence is: 'I like apples, and he likes pears.'
Answer: D. Compound sentence
This is a compound sentence because it joins two full, separate ideas ('I like apples' and 'he likes pears') with a comma and the word 'and'.
-
Q17Which sentence is a compound sentence?
Answer: B. It rained, so we stayed home.
This sentence joins two full ideas ('It rained' and 'we stayed home') with a comma and 'so.' The choice 'It rained, and stayed home' is not compound because the second part is missing a subject.
-
Q18Identify the error in this compound sentence: 'He studied hard but he failed the test.'
Answer: D. Missing comma before 'but'
In a compound sentence, you need a comma before the joining word (like 'but') if there is a new subject after it.
-
Q19Complete the compound sentence: 'She finished her work, ___ she went home.'
Answer: B. so
The word 'so' shows a result. Because she finished her work, she went home.
-
Q20Which is a correctly punctuated compound sentence?

The comma should always go before the joining word 'but,' not after it.
-

Answer: B. or
We use the word 'or' to show a choice between two different options.
-
Q25Which sentence is NOT compound?
Answer: C. He ran and jumped.
'He ran and jumped' is a simple sentence. It has one subject doing two things. A compound sentence needs two subjects, like 'He ran, and he jumped.'
-

-
Q29Which sentence is compound?
Answer: B. It is hot, so I opened the window.

-
Q30Rewrite this simple sentence as a compound sentence: 'He ate lunch.'
