compound-complex sentence and comma rules

0

During the rainy season in Hawaii, temperatures become a little cooler and showers more
frequent
, but the Sun still shines most days.
(A) temperatures become a little cooler and showers more frequent
(B) temperatures become a little cooler, also showers become more frequent
(C) temperatures become a little cooler, showers were more frequent
(D) their temperatures become a little cooler and showers happen more frequently
(E) it becomes a little cooler and they have more frequent showers

 

Answer is A.

I think B is correct too. Why isn't it?

What rules do B - E rely on?

What I know is:

The sentence in question is a compound-complex sentence. The complex sentence is “During the rainy season in Hawaii, temperatures become a little cooler and showers more
frequent" and the compound sentence is “the Sun still shines most days.” “During” is a transition word used to show time and introduces the dependent clause “the rainy season in Hawaii.”  “Temperatures become a little cooler and showers more frequent” and the Sun still shines most days are independent clauses. The complex sentence has a compound subject (“temperatures” and “showers”) and a single verb (become). Note that become is the plural form of the verb. The coordinating conjunction “and” connects the two sentences. The focus of the question is the composition of the complex sentence, specifically the connection between the two subjects. 

 

Thanks for all your help.

'During the rainy season in Hawaii' is an introductory adverbial prepositional phrase answering the question 'when'. It will always be followed by a comma. This is not a clause and will not, in itself, make the sentence complex.

Let's look at the options you have listed.

 

(A) temperatures become a little cooler and showers more frequent

I see this as a compound sentence. You have two subjects, temperatures and showers, and two verbs, although the second instance of become is understood. Because of this, I would put a comma after 'cooler'. My reasoning may be open for debate, however.


(B) temperatures become a little cooler, also showers become more frequent

This is a compound sentence as well, and it is written correctly.

 

(C) temperatures become a little cooler, showers were more frequent

Here, you have a compound sentence but no conjunction. This is called a comma splice. A semicolon should replace the comma.

 

(D) their temperatures become a little cooler and showers happen more frequently

This is a run on sentence. You have the conjunction, but there is no punctuation. There should be a comma after 'cooler'.

 

(E) it becomes a little cooler and they have more frequent showers

This is the same errror as (D).

 

Note that all of your examples should end in a period.
