I
though, is accurate: the author of Passage 1 talks about
the difficulty surgeons have in reconstructing and replacing
bones, and the author of Passage 2 laments surgeons' lack
of experience in using artificial organs. Choices (C) and (D)
are wrong because only the author of Passage 2 demands
an increase in the number of human subjects or mentions
cultural values as a barrier to research. As for (E), neither
author advocates a more rapid development of new
implant procedures.
18. B
Difficulty: Medium
Passage 2 is devoted to arguing for the testing of artificial
organs on humans; the author believes that restrictions on
human testing are a major obstacle to improved devices.
Before checking the choices, predict what the author of
Passage 2 might say about the wider use of osteogenin.
No doubt he'd say that gaining experience with the use of
osteogenin on humans would be difficult-exactly what (B)
says. Choices (A) and (D) cite valid obstacles to the wider
use of osteogenin, but they're incorrect because there's no
reason to think that the author of Passage 2 would stress
them. Choices (C) and (E) are out because they aren't
obstacles to the use of osteogenin at all.
19. D
Difficulty: Medium
The last paragraph of Passage 1 states that the process of
bone prefabrication has not yet been tried on humansthat
it needs to be tested on large animals first. The last
paragraph of Passage 2 features questions about coronary
care that can only be answered through human testing. In
other words, both authors are stressing the need to gather
information that's relevant to the treatment of human
patients, (D). Choice (A) is out because neither author
sees the need to develop new and improved devices for
human implantation. The author of Passage 1 suggests that
experiments should next be carried out on larger animals,
which rules out (C), while the author of Passage 2 wants
testing on humans, which eliminates (B). As for (E), neither
author advocates curbing the growing use of animals in
testing.
SECTION 9
1. E
Difficulty: Medium
Fix awkward sentences by eliminating unnecessary words.
As written, this sentence is awkward and unnecessarily
wordy. Choice (E) is concise and contains no errors. In (B),
the antecedent for the pronoun that is unclear. Choice (C)
and (D) create run-on sentences.
2. B
Difficulty: Medium
Look for the most concise answer that correctly expresses
the relationship between ideas. As written, this sentence is
unnecessarily wordy, and so that does not correctly express
the relationship between the ideas. (The sunblock is the
cause of the harm.) Choice (B) correctly expresses this
with the transition word because. Choices (C) and (D) also
use transition words that are inappropriate in context. The
pronoun it in (E) does not agree with the plural antecedent
sunblocks.
3. E
Difficulty: High
Words like each, one of, and evety are grammatically
singular. This question refers to each of the reporters
but uses were, the plural form of the verb. Also, them
collaborating is grammatically incorrect. Choice (E)
addresses these problems by changing were to was and
uses the noun collaboration. Choice (B) fixes the verb
problem, but not the incorrect pronoun. Choices (C) and
(D) do not address the subject-verb error.
4. B
Difficulty: High
Look for sentence logic as well as sentence style; to what
is which referring here? The phrase of which implies a
selection from multiple choices, but the pronoun's only
antecedent is the singular marketing. Choice (B) eliminates
the pronoun altogether and joins the two independent
clauses with a semicolon splice. The pronoun it in choice
(C) does not have a clear antecedent; this sentence is also
unnecessarily wordy. Choice (D) misuses the semicolon
splice, which is only correct between two independent
clauses. Choice (E) is a run-on sentence.
