This sentence contains an error in the usage of the comma. Commas should only appear before a coordinating conjunction like "and" when the conjunction joins two independent clauses. The phrase "took much pride in the pieces that adorned her walls" is not an independent clause, however. If the phrase had the word "she" before the word "took," then the comma would be appropriate. The correct choice is, "a collector of fine arts and took much pride in the peices."

The phrase "which were essential for the company's records" is an example of a relative clause, which gives more information about its antecedent: the documents. Any such phrase that occurs in the middle of a sentence must be introduced and completed with a comma. You would not use hyphens to separate these clauses; usually, hyphens are more common between clauses when adding an interjection. The correct answer choice, which corrects the error without changing the meaning of the sentence, is "the documents, which were essential for the company's records, meant Fatima would."

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 not incorrect as written in the original form, it is not the best version of the sentence. Since the secondary part has new information not related to the first clause, it is better to start a completely new sentence. The colon and semi-colon are not suitable for this sentence.

This sentence contains an error in verb voice. The phrase "Japanese longswords...are considered..." is in the passive voice. Since there is already an interrupting appositive renaming the subject here, it is best to simply re-phrase this sentence in the active voice in order to avoid an overly wordy and complex sentence. The most clear and concise choice in this instance is, "Many individuals consider Japanese longswords, katanas, the best swords in the world." The other choices are too wordy or contain inconsistencies (e.g. longswords...a katana).

Eliminate the answer choices which include the passive voice. This question also has to do with order of relevance. Consider that the initial prepositional phrase describes the guide's most relevant action. What is the most important thing the guide did? He cleared away the debris. That should be mentioned in the active voice before the fact that he allowed his group to follow his path. Choose the answer that most efficiently describes the primary action (in the active voice) and sets up the clauses about the consequences of his action.

After the comma we need the name of the person. In this sentence the dependent introductory clause (which is not underlined) is "her" which cannot describe a "toe." In order to fix this dangling modifier, the subject of the main clause needs to be changed to "the trapeze artist."

This sentence does not contain a comma where one is needed. The phrase "after running" 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 choice is: "After running, he decided to eat a snack and watch."

This sentence misuses the word "affect." "Affect" is a verb meaning to change. It is clear that the results of the changes (hence, a noun) is meant in this sentence. "Effect" is the correct choice, meaning a change/result of something. No other changes are necessary. The correct choice is, "The effects of the changes saved."
