Correct Answer: A

Rationale: In this sentence, "committee" is a singular noun, so the correct pronoun to use is "its." The possessive pronoun "its" indicates that the committee is taking ownership of the report it finished. Choice B, "their," is incorrect as it is a plural pronoun and does not agree with the singular noun "committee." Choices C and D are also incorrect as they represent contractions ("it's" for "it is" and "they're" for "they are"), which do not fit in the context of showing possession of the report by the committee.

Correct Answer: D

Rationale: The correct answer is 'D: broken.' In this sentence, the word 'broken' is the past participle form of the verb 'break' and is needed to complete the present perfect tense. The correct sentence should be 'The girls have apparently broken curfew at least twice this week.' Choices A, B, and C do not fit grammatically in the sentence because 'broke' is the simple past tense, 'break' is the base form, and 'breaking' is the present participle, whereas the sentence requires the past participle 'broken' for the present perfect tense.

Correct Answer: B

Rationale: The correct punctuation needed in the given sentence is a comma after 'class.' This comma is necessary to separate the two independent clauses 'Do not be afraid to ask questions in his class' and 'he is very approachable and explains things well.' Commas are used to separate independent clauses when they are joined by a coordinating conjunction like 'and.' Choice A, 'Hyphen,' is incorrect as a hyphen is not needed to connect any words in the sentence. Choice C, 'Apostrophe,' is incorrect as there is no possession or contraction being indicated in the sentence that requires an apostrophe. Choice D, 'Semicolon,' is incorrect as a semicolon is not used to join two independent clauses in this context; a comma followed by a coordinating conjunction is more appropriate.

Correct Answer: A

Rationale: The word 'lose' in the sentence is not used correctly. The correct word should be 'lose,' which means to be deprived of or to fail to maintain possession of something. 'Loose' means not tight or free from restraint. In this context, 'lose' is the appropriate term to convey the idea of not maintaining patience or morale.

Correct Answer: C

Rationale: In the given sentence, the word 'effect' is used incorrectly. In this context, the word 'affect' should be used instead of 'effect.' 'Affect' is a verb that means to influence or have an impact on something, while 'effect' is a noun that represents the result or outcome of an action. Therefore, to convey the intended meaning that her mentor's advice was bound to influence or impact her final decision, the correct word should be 'affect,' not 'effect.' The other options ('mentor's,' 'advice,' 'decision') are used appropriately in the sentence and do not contain any errors.
