This sentence uses an unnecessary preposition. While it is convention to speak about “an appreciation for,” the preposition “for” is not used with the verb “to appreciate.” The corrected sentence reads, "Since she had the surgery, Christine has appreciated the elevator up to her fourth-floor apartment."

This sentence doesn’t follow the conventions of prepositions in its choice of preposition that follows the verb “afraid.” “Afraid of” is very different than “afraid for.” In this case, because the speaker’s life is the thing in danger instead of the speaker's life causing the speaker to feel afraid, “for” is appropriate. The corrected sentence reads, "The roller coaster was old and rickety, and the seatbelts were dangerously frayed; getting in, I felt afraid for my life."

The wrong preposition is used in "disagreed with." You generally "disagree with" a person or policy, but "disagree over" or "disagree on" an issue. Changing "with" to "over" corrects the sentence's error. The corrected sentence reads "The Federalists and the Republicans, the first two political parties of the United States government, disagreed over how the Constitution should be interpreted."

The correct phrase is “to prevent someone (or something) from doing something.” 

This sentence does not use prepositions in the correct idiomatic matter. You compromise on an issue and with people. The corrected sentence reads, "The two sides were not prepared to compromise on the matter of wage increases, and the discussions came to a standstill."

This sentence uses the wrong coordinator to connect its different parts. An adjective like “apprehensive” calls for “because” to explain why. The corrected sentence reads, "Joseph was apprehensive because of the unusual number of television crews crowding his front lawn."

In this sentence, the preposition “for” is incorrect. “For” is used after the noun “support,” but not the verb. The corrected sentence reads, "Now that I have researched all of the candidates and the issues, I have decided to support the third party candidate."

There is an error in the idiomatic use of prepositions in this sentence. The preposition “to” is more acceptable after “surprising.” The corrected sentence reads: The presence of a chicken happily pecking at pretzels strewn across her kitchen floor was rather surprising to Margaret.

"In" is the wrong preposition. "Work on" makes more sense.

This sentence uses the wrong preposition after “inspired.” “By” would be idiomatically correct. The corrected sentence reads, "Inspired by the delicious quiche that he tried in a French bakery last weekend, Marvin went on a organic vegetable shopping spree and tried to recreate the perfect breakfast in his own kitchen."
