The point of this problem is recognizing that when it discusses the two effects of the cultural revolution of the 1960s, drug experimentation and sexual exploration, the sentence needs to employ parallel structure. For example, "which led many to experiment with drugs and exploration of their sexuality" isn’t correctly employing parallel structure because it uses one infinitive ("to experiment") and one noun ("exploration") - two infinitives or two nouns could be correct, but one of each is not. The correct answer the only one that employs parallel structure correctly, "leading many to experiment with drugs and to explore their sexuality."

This is a list problem. With lists, we can have an “a, b, and c” list or we can have a list with a structure such as “a and b, as well as c”. Going through all the of the potential answers, "daily exercise and a balanced diet, as well as plenty of sleep" is the only one that meets this criteria. "Daily exercise, having a balanced diet, and plenty of sleep" is almost right, but the “having” is what gives it away as incorrect, since all the items in a list should take the same form (either “exercising daily, having a balanced diet, and getting plenty of sleep” or “daily exercise, a balanced diet, and plenty of sleep”).

It is important for a sentence to have proper parallelism, which means that listed items take on the same grammatical form. The first two items in the list are present tense verbs ("see" and "smell"). Therefore, “tasting” should also be a present tense verb, “taste.” So, the correct answer choice is "must see the food as it simmers, smell its aromas, and of course, taste it."

It is important for a sentence to use proper parallelism, which means that listed items take on the same grammatical form. Here, the first two listed items are nouns ("small bladders" and "short tempers"). Therefore, the third item should also be a noun. However, “tend to be aggressive” is verb phrase, and therefore is incorrect. The correct answer, "small bladders, short tempers, and aggression," corrects this issue by changing the verb phrase "tend to be aggressive" to a noun, "aggression."

There are multiple baristas described in the sentence. Therefore, there should also be multiple (or plural) experts. However, the words used are “an expert,” which is singular and therefore incorrect.

Given that Chef Milan has three restaurants, which is plural, “a huge success” should also be plural. However, it is not. Therefore, that is where the error lies. 

The correct version of this sentence is: "All three of Chef Milan’s restaurants went on to become huge successes; he was extremely pleased with the results and the financial benefits."

It is important for a sentence to employ correct parallelism, which means that listed items should take on the same grammatical form. Here, the first two listed items are nouns ("boutique shops" and "trendy restaurants"). Therefore, the third item should also be a noun. However, “attracts celebrities” is a phrase beginning with a verb, and therefore is incorrect.

It is important for a sentence to have proper parallelism, which means that listed items should take on the same grammatical form. The first two items in the list are gerunds ("doing weight-bearing exercises" and "eating more protein"), so the infinitive “to use” should also be changed to a gerund, "using." Also, in a list of three or more items, there should be a comma preceding "and," which is known as an Oxford comma. This prevents ambiguity from arising in certain sentences.

There are multiple students described in the sentence. Therefore, there should also be multiple (or plural) spatulas. However, the word used is “spatula,” which is singular and therefore incorrect.

It is important for a sentence to employ proper parallelism, which means that listed items should all take on the same grammatical form. Here, the first two listed items are nouns ("prowess" and "independence"). Therefore, the third item should also be a noun, but “they groom themselves” is a phrase using a verb, and is therefore incorrect. Changing "they groom themselves" to “the ability to groom themselves" fixes this error.
