The underlined section of the sample text featured a semicolon error, where a dependent clause ("according to the survey") was linked using a semicolon. The most precise and concise correction would have been to replace the semicolon with a comma.

"According to the survey" is a dependent clause, so to punctuate it with a period would be as incorrect as to use a semicolon.

"As per the survey's findings," would not be grammatically incorrect, but would be less clear and precise than simply replacing the semicolon with a comma.

In order for a colon to be used, the second half of the sentence should either be a list or a quotation.

The use of the semicolon in the sentence is incorrect, as a semicolon needs to separate two independent clauses in a compound sentences, instead of separating a dependent clause from the main part of the sentence it is reliant on. The sentence needs to feature a comma separating the two parts, making the correct answer "The new plan had made a small difference, reducing costs and expenditures somehat over the last year."

Although the sentence is written as compound sentence joined by a semicolon, the first portion, "Drawing the opposing team into an attacking formation," is actually an introductory clause. As such, the clause should be set apart from the rest of the sentence by a comma. Therefore, the correct answer choice is "Drawing the opposing team into an attacking formation, the coach felt he knew exactly what he wanted to do."

The sentence as written as a complex sentence, and it joins its two parts with a semicolon and the conjunction "but;" however, a compound sentence needs to be joined either by just a semicolon or a conjunction and comma, but not a semicolon and a conjunctionl; therefore the correct answer choice is "Pensions are a complicated financial problem for many municipalities, but many cities have made changes to their pension programs in recent years."

A semi-colon separates two independent clauses. No punctuation between "individualism" and "and" is necessary.

This sentence misuses a semicolon. Semicolons are used when joining two independent clauses without the use of a coordinate conjunction. Instead, in this sentence, a dependent clause is joined to an independent clause. The phrase "Even though Samretiredsinger and Apple are constantly engaged in legal battles" is an example of an introductory phrase, explaining information necessary to the context of the sentence, but outside of the main sentence, grammatically. These types of phrases must be followed by a comma in order to separate them from the rest of the sentence. The correct answer choice is, "Samretiredsinger and Apple are constantly engaged in legal battles, Samretiredsinger makes."

This sentence does not contain the correct punctuation where it is necessary. The sentence joins two related independent clauses together without the use of a coordinate conjunction; therefore, a semicolon is necessary between the words "investing" and "he." The correct choice is, "many books about investing; he wanted to become better."

Using the word "however" to join two independent clauses requires the use of a semicolon and a comma. In this case, "however" is not functioning as a conjunctive adverb. It is simply an adverb modifying the word "challenging." Because the modifier "however challenging" interrupts the independent clause, it is best to set it between commas.

The central issue here is how to effectively combine these two independent statements. Because the clauses do not contrast in meaning, using the conjunction but or the conjunctive adverb however after the semi-colon is inappropriate. However, using a semi-colon to join two independent clauses that are closely related is totally acceptable. Using a comma alone would result in a comma splice error. The correct answer simply implements a semi-colon.

When using a conjunctive adjective to join two independent clauses, one should use a semicolon before the conjunctive adverb (in this case "however") and a comma after the conjunctive adverb, in this case "however".
