Correct Answer: B

Rationale: The sentence 'Cooking requires a number of different skills that can be learned and practiced' effectively introduces the main idea of the paragraph, making it a strong topic sentence. Choice A is vague and does not clearly establish the central theme. Choice C focuses on a specific tool rather than the broader concept of cooking skills. Choice D is more about the process of learning a particular skill rather than encompassing the range of skills needed for cooking.

Correct Answer: D

Rationale: Option D correctly punctuates the quotation with commas separating the dialogue from the tag and action.

Correct Answer: B

Rationale: The correct answer is 'B: Joyful.' 'Joyful' is a synonym for 'happy' as both words convey feelings of pleasure, contentment, and delight. Choice 'A: Sad' is incorrect as it is an antonym of 'happy,' representing feelings of sorrow or unhappiness. 'Angry' in choice 'C' and 'Tired' in choice 'D' are also incorrect as they represent different emotional states and do not share the same meaning as 'happy.'

Correct Answer: A

Rationale: Proofreading is an essential part of the last step in the writing process. During proofreading, you carefully review your written work to correct errors in grammar, punctuation, spelling, and formatting. This step ensures that your writing is polished and error-free before submission. Brainstorming, citing primary sources, and identifying a thesis are typically parts of the earlier stages of the writing process. Brainstorming involves generating ideas, citing primary sources is about researching and providing evidence, and identifying a thesis is establishing the main argument or focus of your writing.

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.'
