This sentence is structured as an independent clause about a priority and then a clarification of what that priority is.

The only appropriate punctuation here is a colon, which will provide that correct structural division and allow the second part of the sentence ("studying physics before her final exam the next morning") to act as an explanation of the noun "priority."

INCORRECT EXPLANATIONS:

A semicolon connects two separate independent clauses, so that is incorrect.

Janine's priority is "studying," which is a gerund, so the past tense "studied" is incorrect.

The option that uses a comma is incorrect because the second clause is dependent and is lacking a subject.

The option that uses a colon unnecessarily includes the connector "and that was." These superfluous words cloud the sentence's meaning and make the sentence grammatically incorrect.

The use of the verb "learn" is essentially as a modifier of the students "shock." This means that "learning" must be turned into a form that will describe why the students were "shocked." "Were shocked to learn," using an infinitive form, is the best choice among the answers.

The sentence employs both the present-tense verb "make" and the past-tense verb "learned." Both of these verbs need to agree and employ the same tense. The only answer choice that correctly adjusts the tenses of the sentence's verbs is "Young professionals often make mistakes, but they also learn from them."

The word "thinking" is acting like a participle in the original sentence, making the first clause lack a verb. Changing "Many parents mistakenly thinking" to "Many parents mistakenly think" corrects the sentence's error.

For this sentence, we need to correct the tense of the verb "go" such that it makes sense when used in the sentence with "stopped by." We know that Sam visited the grocery store "before he stopped by the bakery," so we need to pick out the past tense of "go," because we are told that Sam "stopped by" the bakery in the sentence, and "stopped by" employs the past tense. We also know that Sam visited the grocery store "before he stopped by the bakery," so the correct form of "go" must also employ the past tense. While both "went" and "gone" might look like potentially correct answers, "gone," when used as a verb, is the past participle of "go" and must be used with a helping verb like "has" or "had" to be grammatically correct. The answer choice "gone" does not include a helping verb, so we know that it can't be correct. "Went," however, is the past tense of "go," so "went" is the correct answer.

Since the sentence is referring to an action in the near future, the simple future tense is best (“will finish”). This is the clearest and most concise option.

One can never say “If I would have done”. One can only say “If I had done”, which is called the past perfect verb form.

The underlined phrase takes the form of an infinitive verb phrase, meaning "to remaining" is an incorrect construction. The appropriate form of an infinitive is "to remain," making "to remain popular" the correct answer.

In this sentence, the action of visiting the university is identified as taking place earlier in time than the action of applying to go there. To reflect this, the past participle should be used for the earlier action, while the past tense should be used for the later action. Only the correct answer choice includes the correct verb tenses.

The past participle of the verb “to ride” is “ridden.” “Rode” is the simple past tense.
