Question: Which sentence is punctuated correctly?
Options:
Answer: The correct answer is:
Explanation: When a conjunction joins two independent clauses, a comma is needed before the conjunction. In the answer chosen, we can observe that it uses a comma before the conjunction ''and,'' which is linking two independent clauses. This is the correct form to use the comma.
Answer:
The answer is the last option: Our class is learning about plant cells, and Reza’s class is learning about animal cells.
Explanation:
This question concerns the use of commas to punctuate correctly. The reasons why the first three sentences are incorrect are as follows:
1. They use commas to separate the subject and the verb:
- and Reza’s class, is learning about animal cells (sentence 1);
- Our class, is learning about plant cells and Reza’s class, is learning about animal cells (sentence 2).
2. They use a comma to separate the verb and the object for no apparent reason:
- Our class is learning, about plant cells (sentence 1).
3. They do not use a comma to separate two independent clauses connected by the coordinating conjunction "and":
- Our class is learning about plant cells and Reza’s class is learning about animal cells.
That's why sentence 4 is the correct one. It properly uses a comma to separate the two independent clauses connected by "and". It does not separate subjects from verbs or verbs from their objects.
- Our class is learning about plant cells, and Reza’s class is learning about animal cells.
