- The author's purpose in mentioning both shallow roots and a deep taproot is to
Answer: show that a cactus has multiple strategies for finding water.
The correct answer is B.

- The author's primary goal in this passage is to
Answer: summarize the remarkable and unusual life of a specific person.
When you encounter a question asking about an author's "primary goal" or "main purpose," you need to step back and look at the passage as a whole rather than getting caught up in specific details.
This passage tells the story of Violet Jessop, focusing on her extraordinary experience of surviving three major ship disasters. The author presents her life chronologically, emphasizing how remarkable and "almost unbelievable" it was that one person could survive the Olympic collision, the Titanic sinking, and the Britannic disaster. The passage concludes by noting her nickname "Miss Unsinkable," which reinforces that her unusual survival story is the central focus.
Choice D correctly identifies this primary purpose: summarizing the remarkable and unusual life of a specific person. The author is presenting Jessop's extraordinary story of maritime survival.
Choice A is wrong because while the Titanic is mentioned, it's just one of three disasters discussed, and the author doesn't provide detailed information about the sinking itself. Choice B incorrectly suggests the author is making an argument about workplace safety in general, but the passage focuses specifically on one person's unique experiences rather than broader industry conditions. Choice C is incorrect because the author doesn't analyze safety flaws or technical problems with these ships—the focus remains on Jessop's personal story of survival.
When answering main purpose questions, always ask yourself: "What is the author's overarching goal?" Look for the thread that connects all the details together, and don't be distracted by topics that are mentioned but aren't the central focus.
- Why does the author state that the "no cutting, gluing, or marking" rule makes origami "both a challenge and a marvel"?
Answer: To highlight the skill required and the amazing results produced within these limits.
The correct answer is C. By calling the constraint a "challenge," the author points to the difficulty and skill involved. By calling it a "marvel," the author emphasizes how impressive the final sculptures are, given the strict limitations. (A) is incorrect as the author presents the rule as a key feature, not something to be changed. (B) is an unsupported claim; the passage treats origami as a legitimate art and science. (D) is incorrect because the point is about what is not used, rather than what is needed.
- The author begins the passage with a question in order to
Answer: engage the reader's curiosity before providing an explanation.
The correct answer is C. Posing a direct question at the beginning is a common writing technique to make the reader interested and want to find out the answer, which the rest of the passage then provides. (A) is incorrect because the passage immediately says "The answer lies..." and proceeds to give the answer. (B) is incorrect because the purpose is to make the topic accessible, not to label it as confusing. (D) is incorrect because the author does not expect the reader to know the answer, but rather intends to teach them.
