English and Language Usage TEAS

Correct Answer: C

Rationale: The prefix 'intra-' means 'within.' 'Intravenous' refers to something within a vein. It is commonly used to describe medications or fluids administered directly into a vein. The correct answer is C: Within veins. Option A, 'Across veins,' is incorrect as 'intra-' does not imply movement across something. Option B, 'Between veins,' is incorrect as 'intra-' refers to within, not between. Option D, 'Outside veins,' is incorrect as 'intra-' denotes inside or within, not outside.

Correct Answer: C

Rationale: The correct answer is C because "It's" is the contraction for "it is" or "it has," while "its" is the possessive form. In this sentence, the contraction "It's" is correctly used to indicate that something has often been said. Choices A, B, and D all incorrectly use "Its," the possessive form, which does not fit in the context of the sentence. It is important to pay attention to the usage of contractions and possessive forms to ensure correct word usage in sentences.

Correct Answer: A

Rationale: The correct answer is A, ambiguous word choice. In the given sentence, the word "it" is ambiguous as it could refer to either the lake or the day. This ambiguity can lead to confusion for the reader. To clarify, the sentence could be revised to explicitly state what "it" refers to. Choice B, inappropriate transition word choice, is not the issue as the transition word "therefore" is used correctly to show cause and effect. Choice C, tense disagreement, is not the problem because the sentence maintains consistent tense throughout. Choice D, incomplete sentence, is also not correct as the sentence is grammatically complete.

Correct Answer: B

Rationale: The correct answer is B: "The weather will affect our plans." 'Affect' is a verb that means to influence or have an impact on something. In this sentence, the weather will influence or impact our plans. Choice A uses 'effect' as a noun, which is incorrect. Choice C incorrectly uses 'affect' as a noun instead of a verb. Choice D uses 'effect' as a noun, not a verb. Therefore, choice B is the only sentence that uses 'affect' correctly as a verb in the context provided.

Correct Answer: D

Rationale: The correct answer is D because it clearly explains the appropriate context for using the word "ain't." Academic writing requires standard language usage, and "ain't" is considered colloquial and informal. It emphasizes the importance of using formal language in academic settings. Choice A is incorrect because the word "ain't" may not be in some dictionaries, but that doesn't mean it isn't used or accepted in certain contexts. Choice B is incorrect as it implies that being in college determines the appropriateness of using "ain't," which is not a valid justification. Choice C is incorrect as it unfairly stigmatizes the word as sounding uneducated; language is diverse and context-dependent.
