Question

Identify the correctly written compound sentences. Check all that apply. Sending quick, irrational replies to upsetting e-mail messages can be emotionally gratifying; however, it is not wise. Informational messages are usually organized in a direct manner but sensitive messages are often indirect to avoid offending the recipient. Good writers use parallel structure in lists to display strong logic; bad writers create unparallel lists that lack logic. Pie charts should be used to show relationships between parts of a whole, but bar graphs should be used to illustrate differences between items or variables.

Answer 1

Definition

Compound sentences are sentences that cointain two ideas (clauses = subject + verb) joined by a coordinating cojunction (these can be "and, but, for, so, or, yet) and they can also be linked by punctuation marks and the use of words like: "however, moreover, besides, as a result, for example,therefore" and several more.  

Answer

• Sending quick, irrational replies to upsetting e-mails can be emotionally gratifying; however, it is not wise.

"Sending quick, irrational replies to upsetting e-mails" = SUBEJCT

"can be emotionally gratifying" = VERB

This is the first clause that is linked to the following by the use of the ";" and the word "however".

";however, it = SUBJECT

is not wise.= IS

This is the second clause of this sentence.

We claim that this is a compound sentences because each clause, each idea can be understood independently and they are joined by the use of a conjuction.

• Good writers use parallel estructure in lists to display strong logic(1st clause); bad writers create unparallel lists that lack logic(2nd clause).

"Good writers" = SUBJECT

"use" = VERB

These are the subject and the verb of the first clause.

";" links the two cluses.

"Bad writers" = SUBJECT

"create" = Verb

These belong to the second clause.

• Pie charts should be used to show relationships between parts of a whole, but bar graphs should be used to illustrate differences between variables.

"Pie charts" = SUBJECT

"be used" = Verb

These elements belong to the first independent clause.

",but" = this conjunction joins the two clauses

"Bar graphs"= SUBJECT

"be used" = Verb

These two elements form the second independent idea of this sentence.

INCORRECT SENTENCES

• Informational messages are usually organized in a direct manner but sensitive messages are often indirect to avoid offending the recipient.

In this sentence the conjuction "but" should be preceded by a comma, otherwise it is incorrectly punctuated and it is not a compound sentence. Compound sentences can have the following structure:

1st clause + Comma + Conjuction + 2nd clause =

I am really tired of studying, but I have to graduate some day.

1st clause + Semi colon + Conjunction + 2nd clause =

It was a difficult test; however, I passed it!

1st clause + comma + 2nd clause =

I'm studying right now, I can't go to the movies.
