The instance that correctly employs an in-text citation as per MLA guidelines is:
D. Nutritionist Soon-yu Kim refers to whole foods as the "cornerstone of a healthy diet" (23)
MLA format utilizes the author-page citation style, necessitating the author's surname alongside the page number. If the author's name is included within the text, only the page number should appear in parentheses at the sentence's conclusion. This explains why A is incorrect because it redundantly repeats the author's name, and C incorrectly positions the page number near the author's name.
Dhruv: How about catching a movie, Madhav?
Madhav: I'm afraid I CANNOT (this indicates Madhav is unable to attend). I NEED (suggests he has to do something, and it’s the only suitable word to precede ‘to’) to get home right away.
Dhruv: But why SHOULD (this is a courteous way to inquire about someone’s actions) you be in such a rush?
Madhav: My mom is unwell. I MUST (means ‘need to’, but since there's no ‘to’ following it, it's the only logical choice) take her to the hospital without delay. Dad is away.
Child labor in factories and various industries was widespread.
This is the most accurate choice. The text suggests that the issue of child labor was significant enough to prompt the formation of a committee advocating for the rights of children. The other alternatives appear less plausible; if most business owners deemed child labor intolerable, a committee wouldn't have been necessary. Additionally, the passage doesn't assert that work was an unacceptable substitute for formal education. While it does mention that limiting the working hours for children would allow more time for school, it does not imply that work serves as an alternative to education. The rationale for selecting the first option contradicts the latter. It’s either prevalent or uncommon.
C. "He was a brilliant talker"; D. "a way of whisking his tail which was somehow very persuasive"; E. "he could turn black into white." These specific details illustrate the central theme that a convincing speaker can instill belief in others, even in falsehoods.
