Structure Section
1. B: second only to. This is an idiomatic expression.
2. B: was foraged. The progressive in the active voice would make sense, which
would be was foraging.
3. A: the tighter it became. This is a double comparative sentence, and the order
is more + {adjective or adjective+-er} . . . more + {adjective or adjective+-er}.
It means that as one condition increases or changes, the other one does too.

4. B: planning. This is part of a noun phrase and should be a noun, plan.
5. A: Due to her agility and speed. The choices with because misuse grammati-
cal rules. The rule is because + clause or because of + noun phrase. Due to
means the same thing and is followed by a noun or noun phrase.

6. A: it. The relative pronoun that replaces the noun, so the pronoun it is repeti-
tive and does not belong.
7. A: that. This is an idiomatic expression, and the order is not until . . . that.
8. A: not best. The superlative structure requires the definite article the because
it is the one item that meets the definition. It should read not the best.
9. D: in greater numbers. This is an idiomatic expression.
10. C: causing. The sentence does not have a conjugated verb unless causing is
changed to caused. The word learned is a past participle from a reduced rela-
tive clause — that were learned. So the subject of the sentence is the issues
and after the relative clause appears the verb, caused.
11. D: the message to all directors. The order is subject + verb + direct object +
to + indirect object. The other alternative is to omit the to and reverse the di-
rect and indirect object — subject + verb + indirect object + direct object
12. A: when black. The article a is missing. Note that the sentence has an unusual
structure because it begins with only when. For that reason, the word will is
correct. The last verb structure in the sentence, be closed down, is in the pas-
sive voice and is correct.
13. C: she has had. The second clause must have a subject.
14. B: accuse. The verb is in the passive voice: are sometimes accused (be + verb
in past participle).
15. B: out of. The idiomatic expression is out of order, which means not working.
16. D: in way. This is an idiomatic expression, in the way.
17. D: did so in. The phrase did so stands for competed. The first clause of the

sentence is dependent, so there must be a conjugated verb in the second
clause; in this case, it is an unusual conjugated verb, but it is one. The second
answer choice is incorrect because it is in the wrong tense.
18. A: completed. It is part of a verb phrase with a modal, could, so it must be in
simple form, complete.
19. D: other. The word another must be used with the singular countable noun
program. Other would be used with noncountable nouns or plural countable
nouns. Notice that the initial part of the sentence is correct. It is the same as
saying the fact that Allen had not completed. . . . The word Allen’s is posses-
sive because it is followed by a gerund, having. Completed is in the past par-
ticiple as part of that construction.
20. B: requires. The subject of the sentence is an infinitive, to master, and it takes
a singular conjugated verb.
21. A: enjoys. The subject of the sentence is a that clause, which is singular, but
it contains a plural noun, investors. The verb should be enjoy to match the
plural noun within the clause.

22. B: has not. The first clause of the sentence is dependent, so the second must
have a conjugated verb. The expression the number of is a singular concept,
and you should not be confused by the plural noun after the preposition of.
23. C: believe. The entire sentence is in the passive voice, and that is why all the
main verbs are in the past participle. This verb should be believed.
24. A: be. The verb phrase had + subject + verb in past participle means the same
as if + subject + had + verb in past participle, so the correct construction
would include been.
25. A: who has sung. This clause is a relative clause and thus requires a relative
pronoun.
Reading Section

1. A: affixed.
2. B: discharge.
3. B: different in that a vent involves rapid discharge while a seep involves slow
discharge. The author uses the two words in different contexts.
4. C: from the same family but different species.
5. A: grows slower than the hot-water tube worm. See paragraphs two and five,
which distinguish between the growth rates of the two worms.
6. A: complete.
7. A: lifetime.
8. C: boiling.
9. D: different in that one contains oily materials and the other contains hydro-
gen sulfide.
10. C: aneurysms that occur near the brain stem only. The first paragraph ex-
plains that these aneurysms are dangerous to repair with surgery.
11. A: aneurysms. The noun is found in the previous sentence, and no other noun
in the sentence could make sense.
12. C: significant.
13. B: aneurysm. The noun to which one refers actually appears two sentences
before the reference.
14. A: meandering. The idea is that it moves slowly and deliberately towards its
destination.
15. A: removed.
16. B: a hernia.
17. D: hemorrhaging that results in death. The first paragraph states that this can
occur in 50 percent of patients.

18. B: serve as a base for a blood clot to form. This is explained in the second
paragraph.

19. B: in the upper thigh. In the reading, it states that the femoral artery is in the
groin area. The word “femoral” is related to femur, which is the thigh bone,
and the groin area is where the thigh meets the hip area.
20. D: separate the coil from the wire. This is explained in the second paragraph.
After the coil is outside the catheter, a low voltage electrical current is ap-
plied, and the coil detaches at a preset solder point.
21. C: at a predetermined and prepared location on the wire. The same sentence
that answers question 20 says it is a preset location.
22. A: longer and require more recuperation time than the new procedure. This
is explained in the last paragraph where it says: The procedure lasts two
hours, which is half as long as invasive surgery, and recovery time is gener-
ally limited to a few days instead of a few weeks.
23. B: is performed only at hospitals containing the required equipment and cer-
tified doctors. This is also explained in the last paragraph where it says: . . . is
available in various hospitals where there are advanced neurology depart-
ments and specialists trained in the procedure.
24. B: carnivorous dinosaur. Carnivorous means the same as meat-eating, which
is stated in the first sentence.
25. B: in addition to.
26. A: frightening.
27. D: surprising.
28. A: lived and hunted with others. The first paragraph states that it is more as-
tounding that the bones were found with other bones, because that indicates
they were not loners.
29. A: meat-eating dinosaurs lived alone. The same sentences say that this dis-
covery challenges the prior theory that they were loners.
30. C: Giganotosaurus.
31. B: not closely related to Tyrannosaurus Rex. The passage states that it is as
close to T. Rex as a cat to a dog, which is not close.
32. A: dismember.

33. A: victim.
34. B: combined.
35. B: thread.
36. C: it is more precise than previous techniques. The passage indicates that
they will have control, whereas they previously did not.

they have known this for a while.
