Jon's mother did not let him organize a garage sale for the family because she did not like the idea of strangers being able to peruse their many belonging. No error

After learning that many experts believe that fear is a healthy evolutionary responses, he felt significantly less afraid of the dark. No error
"Responses" is incorrect in this sentence as it is part of the phrase "a healthy evolutionary responses."

Changing "responses" to "response" would correct the sentence's error.

She runs very fast; sometimes it's quite uncanny. No error
In the example sentence, the word "fast" is used to describe how the subject of the sentence runs, and the word "very" is being used to modify this description. Therefore, it is correct should use an adverb (for instance swiftly or quickly) in place of "fast." Anytime the manner in which an action is performed is described it is correct to use an adverb, rather than a modified adjective (or any adjective at all). Adverbs describe some of the most important aspects of life, not merely the subject and the verb that subject did, but the way that thing was done.

"That blond man is real suspicious," said John. No error
Here, the world "real" is being used to describe "the blonde man's" level of suspicion, and it seeks to do so by modifying the verb "is." Given that the word in question should be an adverb, you need to replace it with a word such as "really."

Which of the two track stars will be quickest than the other? No error
In the sentence above, the phrase "which of the two track stars" is being modified by the word "quickest." Only two things are being compared, so a comparative adjective should be used, rather than a superlative. Superlatives are used when one item is being distinguished from a group of 3 or more items; comparatives are used to directly compare two items. The best way to correct the sentence above is:
"Which of the two track stars will be quicker than the other?"

Josie ran as quick as the wind; she knew that she needed to gain some distance now, if she wanted a chance to win the race. No error

Jordan and Marvin’s mother has decided that they will become a lawyer when they grow up, but they seem more artistically inclined. No error
This sentence's error is a discrepancy in number. Two children are mentioned, "Jordan and Marvin," so logically, they would grow up to become two different lawyers. The sentence uses the singular noun "a lawyer" where it should use the plural noun "lawyers," so "lawyer" is the correct answer.
The corrected sentence reads, "Jordan and Marvin’s mother has decided that they will become lawyers when they grow up, but they seem more artistically inclined."

As part of their development, caterpillars form a cocoon and eventually emerge as moths or butterflies. No error
This sentence's error is a problem with agreement of plurals. Multiple "caterpillars" should form multiple cocoons, but the sentence uses the singular noun "a cocoon," which doesn't make sense. "A cocoon" is thus the correct answer, and the corrected sentence reads, "As part of their development, caterpillars form cocoons and eventually emerge as moths or butterflies."
