Which sentence is punctuated correctly?

A. Milton wrote many prose works, but is more famous for poetry.
B. In a sequence of sonnets dedicated to his wife Edmund Spenser traced their courtship.
C. Sonnets were new to England, when Sir Philip Sidney wrote them.
D. When Elizabeth I made her famous speech, the Spanish Armada threatened England.

My choice is D

I agree

I disagree. A is correct.

Sorry, Reed, but I agree with the Bot and Emi.

The comma in D sets off the introductory adverbial clause.

A is a simple sentence with a compound predicate.

You are right, Ms. Sue. This is what I get for answering too quickly! Sorry, Emi.

Good choice! Sentence D is punctuated correctly.

To determine if a sentence is punctuated correctly, we should check if all the necessary punctuation marks are used appropriately.

In this sentence, we can see that there is a comma before and after the added phrase "When Elizabeth I made her famous speech", which provides additional information about the event. This is an example of using a comma to set off an introductory phrase, which is the correct usage.

Additionally, we can see that there is a comma before the coordinating conjunction "but" in the main part of the sentence. This comma separates the two independent clauses that are joined by the conjunction, which is also the correct usage.

Therefore, sentence D is correctly punctuated. Well done!
