Correct Answer: A

Rationale: The correct answer is A: Parallelism. The sentence contains a parallelism error in the list of actions required for the project. In a series or list, all elements should be in the same grammatical form. In this sentence, 'researching' and 'writing' are in gerund form, but 'presenting' is in infinitive form. To ensure parallel structure, all items in the list should be in the same form. Therefore, the corrected version should read, "The project requires researching, writing a report, and presenting findings." Choices B, C, and D are incorrect. There are no sentence fragments, misplaced modifiers, or subject-verb agreement errors in the original sentence.

Correct Answer: D

Rationale: The correct answer is 'Anaesthetic'. 'Anaesthetic' refers to a drug that removes feeling or sensation. The prefix 'ana-' means without, and the root 'esthetic' relates to sensation or feeling. 'Hyperalgesia' refers to increased sensitivity to pain, 'Subcranial' does not relate to drugs or removing sensation, and 'Hypoglycemic' refers to low blood sugar levels, not a drug that removes feeling or sensation.

Correct Answer: A

Rationale: Choice A demonstrates correct punctuation. The sentence uses a colon to introduce a list, which is the most appropriate punctuation in this context. A colon is typically used to signal that a list or explanation follows, making it the suitable choice here. Choices B, C, and D either use a comma, semi-colon, or dash incorrectly to introduce the list, deviating from the standard punctuation rule for listing items. Therefore, they are incorrect in the context of this sentence.

Correct Answer: A

Rationale: The correct answer is A: 'Around, surrounding.' The prefix 'circum-' commonly means 'around' or 'surrounding,' as observed in words like circumference (the distance around a circle), circumnavigate (to sail or travel around something), and circumstance (a condition surrounding or related to an event). Choices B, C, and D are incorrect because the shared meaning among these words is related to being around or surrounding, not travel, transport, size, measurement, area, or location.

Correct Answer: C

Rationale: Option C correctly punctuates the sentence by placing commas after 'Chicago' and 'Illinois' to separate the location details and inserting a comma before 'in 1948' to separate the location from the date. This creates a clear and grammatically correct sentence. Choices A, B, and D incorrectly place the commas, leading to confusion or incorrect grouping of the location and date information.
