      1 D. The first paragraph “shows” the reader a garden that’s lopsided, with all the “tall delphiniums off center … or the large yews on one side” (Lines 5–6). The garden image is preceded by the statement that “people trim the natural shapes” (Lines 2–3) because of a need for “balance” (Line 5). Symmetry means balance, so Choice (D) is your answer. Were you fooled by Choice (A)? True, the first paragraph talks about what human beings find “more appealing” (Lines 1–2), but Choice (A) is too vague.

      2 A. Take a look at the explanation for Question 22. You see that all the garden comments support a need for balance, with the garden as an example. Choice (A) is correct.

      3 B. The passage explains that a garden with all the tall plants on one side or all the big trees clumped together “just does not seem adequate” (Lines 7–8), which reads like, “just not good enough.” In other words, it’s not satisfactory, and Choice (B) is your answer.

      4 B. The second paragraph of the passage (Lines 20–27) is the only one to deal directly with philosophy. The author gives an example of balance in math, with positive numbers requiring the existence of negative numbers. The author also states that “[t]he true, the good, and the beautiful all have their opposite partners” (Lines 26–27). Put those two ideas together — as the author does in paragraph two — and you arrive at Choice (B). The other choices are all the sort of vague statement that philosophers love to debate, but only Choice (B) is justified in the passage.

      5 C. The explanation for the answer to Question 25 points you to the second paragraph, where the concept of balance is illustrated with examples from both math and philosophy. Choice (C) combines these ideas and is the correct answer.

      6 A. The balanced garden of paragraph one (Lines 1–19) is similar to Choices (B) and (C) — both examples of visual symmetry. The passage also discusses balanced actions (Line 22: “an equal and opposite reaction”), so Choice (D) doesn’t work. You’re left with Choice (A). A forest doesn’t necessarily grow in a balanced, patterned way, so it’s not an example of symmetry.

      7 C. Antimass is called “nonexistent” in Line 34, but the passage states that “the need for balance is so strong … that one day antimass will be found” (Lines 31–33). Sounds like Choice (C)! The prize for runner-up goes to Choice (A), because antimatter balances out matter. However, Choice (C) addresses the balance issue directly, so it’s a better answer.

      8 D. The passage explains that by the time the existence of antimatter was proved experimentally, it had already been predicted mathematically because of a fundamental quality of Nature — its tendency to be balanced. Therefore, Choice (D) is your answer.

      9 A. Lines 40–41 describe the way in which scientists put ideas together (“interpreting a mathematical treatment”) to reach a “conclusion,” or judgment. Choice (A) is your answer.

      10 A. The last paragraph talks about the lack of balance sometimes found in Nature and goes on to say that if balanced pairs don’t exist now, “at some earlier time or in some other physical state the balance once did exist” (Lines 52–54). Therefore, Nature tends toward balance, and anything unbalanced now was balanced at some point or is balanced in some other way. This is why Choice (A) is the correct answer.
