Explanation:

Comma splice error occurs when two independent clauses are joined by only a single comma. One option is to simply make the two independent clauses into separate sentences. If you wish to join two independent clauses into a compound sentence, you may either use a comma followed by an appropriate coordinating conjunction or you may use a semicolon without a conjunction. The only correct option provided adds the coordinating conjunction "and" after the comma.

Explanation:

The example sentence makes a comma splice error, since both clauses are independent and they are joined only by a comma. Comma splice errors can be fixed by making the clauses into their own sentences, or joining them into a compound sentence with either a semicolon or a comma and an appropriate coordinating conjunction. All three options are equally grammatically correct, whichever you choose depends on your own personal writing style.

Explanation:

A comma splice error occurs when two independent clauses are joined by only a single comma. One option is to simply make the two independent clauses into separate sentences. If you wish to join two independent clauses into a compound sentence, you may either use a comma followed by an appropriate coordinating conjunction or you may use a semicolon with no accompanying conjunction. In the sentence above, the second independent clause makes a contradictory statement, so adding the coordinating conjunction "but" is the best way to fix the splice.

Explanation:

A comma splice error occurs when two independent clauses are joined by only a single comma. One option is to make the two independent clauses their own sentences. The other is to join them into one compound sentence, if you choose to go that route, you can either join the clauses with a semicolon instead of a comma, or a comma followed by an appropriate coordinating conjunction. In this case, since a contrast is being indicated, the coordinating conjunction "but" is the best choice.

Example Question #352 : Correcting Punctuation Errors

Replace the underlined portion with the answer choice that results in a sentence that is clear, precise, and meets the requirements of standard written English. One of the answer choices reproduces the underlined portion as it is written in the sentence.

My father is an excellent attorney, he has represented a broad array of clients.

Possible Answers:

My father is an excellent attorney he has represented a broad array of clients.

My father is an excellent attorney; he has represented a broad array of clients.

My father is an excellent attorney; while he has represented a broad array of clients.

My father is an excellent attorney, he has represented a broad array of clients.

My father is an excellent attorney; and he has represented a broad array of clients.

Correct answer:

My father is an excellent attorney; he has represented a broad array of clients.

Explanation:

In the example sentence, both "my father is an excellent attorney" and "he has represented a broad array of clients" are both acting as independent (main) clauses, and thus joining them with only a comma is incorrect. This species of error is called a comma splice. If you wish to join two independent clauses into one compound sentence, you can either use a semicolon, or a comma and a coordinating conjunction. The only correct answer option uses a semicolon.

Note also, that semicolons, when used in this manner, cannot be followed by a coordinating conjunction.

Explanation:

When two independent clauses are joined only by a single comma, this results in an error known as a "comma splice." In the example above, something more than a comma is needed to separate the two clauses, and the only correct answer option provided adds the coordinating conjunction "and" after the comma.

Example Question #91 : Correcting Punctuation Errors: Comma Splices

Are you trying to stick to a budget? Using coupons for purchases, also known as “couponing” is a great way to save money on groceries. Coupons are a little piece of paper that can give you a discount on what you buy. You will be amazed at the great bargains and amazing savings you can get!

It’s easy to get started. When you open up your daily newspaper, one might find a glossy insert full of coupons. Some of the coupons will be for things you don’t buy, some will be for things you buy all the time. Go through the coupons and chop out the ones you can use.

The key to successful couponing is getting multiple copies of coupon circulars. Ask your friends, your neighbors, and family if they have any extras. Some coupon users even go through the recycling at their office to find more coupons! Have you ever heard of such a thing in your life! Completely devoted, these circulars help coupon users to get even more savings.

Couponing might sound like hard work, but for many people, it’s also a hobby. Not only does it help them save hundreds of dollars per year, but also it gives them a fun challenge every time they do their shopping. 

How should the underlined section be corrected?

Possible Answers:

Some of the coupons will be for things you don’t buy and some will be for things you buy all the time.

Some of the coupons will be for things you don’t buy, but some will be for things you buy all the time.

NO CHANGE

Some of the coupons will be for things you don’t buy but some will be for things you buy all the time.

Some of the coupons will be for things you don’t buy some will be for things you buy all the time.

Correct answer:

Some of the coupons will be for things you don’t buy, but some will be for things you buy all the time.

Explanation:

This question asks you to correct a comma splice error. A comma splice occurs when two complete sentences are joined with just a comma. We have two options to correct a comma splice. We can either replace the comma with a period to create two complete sentences, or we can use a comma and a conjunction. In this context, the second sentence provides a contrast to the first sentence, so it is appropriate to use a comma and the conjunction “but.” Eliminating the comma creates a run-on sentence even if the conjunction "but" is added. The use of the conjunction "and" is grammatically correct, but it is not as strong a choice since it does not communicate the contrast between the two sentences. 

Example Question #1 : Correcting Punctuation Errors: Commas In Lists

Replace the underlined portion with the answer choice that results in a sentence that is clear, precise, and meets the requirements of standard written English. One of the answer choices reproduces the underlined portion as it is written in the sentence.

Angles, Jutes, and Saxons, were the dominant tribes that invaded Britain during that era.

Possible Answers:

Angles, Jutes, and Saxons were

Angles, Jutes, and Saxons, were

Angles Jutes, and Saxons were

Angles Jutes Saxons were

Angles, Jutes, Saxons, were

Correct answer:

Angles, Jutes, and Saxons were

Explanation:

The list that forms the subject of the sentence, "Angles, Jutes, and Saxons," appropriately separates its items with commas. The comma between "Saxons" and "were" splits the subject of the sentence from the verb, and should be removed. This makes "Angles, Jutes, and Saxons were" the correct answer choice.
