Correct Answer: B

Rationale: The correct answer is 'B: On.' The prefix 'epi-' means 'on' or 'upon,' as seen in the word 'epidemic.' An epidemic refers to a situation where a disease spreads rapidly and affects many people. Choice 'A: Badly' is incorrect as it does not accurately represent the meaning of the prefix 'epi-.' Choices 'C: A lot' and 'D: A little' are also incorrect as they are not related to the prefix 'epi-' in the context of the word 'epidemic.'

Correct Answer: D

Rationale: The correct answer is 'Compare/contrast.' This structure is specifically designed to analyze and highlight the similarities and differences between two subjects, making it the most appropriate choice for an essay discussing the similarities and differences between World War I and World War II. Choice A, 'Technical,' typically involves detailed, specialized information rather than comparison. Choice B, 'Expository,' focuses on explaining or describing a topic without necessarily comparing or contrasting different subjects. Choice C, 'Cause/effect,' is used to examine the causes and consequences of events, which is different from directly comparing and contrasting two historical events like World War I and World War II.

Correct Answer: A

Rationale: The correct order for the sentence 'yesterday she went to the store' is 'She went to the store yesterday.' In English, the standard word order for a sentence is subject-verb-object-adverbial (time). Choice A is the correct answer as it follows this standard order. Choice B changes the order of the subject and object. Choice C changes the order of the adverbial and subject. Choice D changes the order of the subject and adverbial. Therefore, choices B, C, and D are incorrect.

Correct Answer: A

Rationale: The correct answer is 'Dyskinesia.' By breaking down the word parts, 'dys-' means difficult or abnormal, and '-kinesia' refers to movement. Therefore, 'Dyskinesia' means an abnormality of movement. Choice B, 'Hyperkinesia,' is incorrect as 'hyper-' means excessive, not abnormal. Choice C, 'Akinesia,' is incorrect as 'a-' means without, not abnormal. Choice D, 'Hypokinesia,' is incorrect as 'hypo-' means deficient, not abnormal.

Correct Answer: C

Rationale: The sentence discusses evidence and clinical trials related to a specific therapy, indicating a scientific context. Scientific journal articles are known for presenting research findings, discussing evidence, and proposing further studies, making them the most suitable source for this type of information. Choices A, B, and D are incorrect because a motivational speech is more focused on inspiring and encouraging, a business memo typically deals with internal communication in organizations, and a personal blog reflects individual opinions or experiences, none of which align with the content and tone of the sentence provided.
