A. NO CHANGE
B. a person who knew the ins and outs of public underground trains.
C. a master of all the skills necessary to travel by public transport.
D. a veteran rider.

Correct answer: A


 The underlined portion as it stands gives an appropriate amount of information without becoming redundant or long-winded. Both choice (B) and choice (C) convey similar information but with more unnecessary words. Choice (D) leaves out the crucial point that the narrator is talking about riding the subway, as opposed to a horse or a motorcycle, for example.

According to Figure 1, the incidence of virus A is greatest during which season of the year?

A. Spring (Mar-May)
B. Summer (Jun-Aug)
C. Fall (Sep-Nov)
D. Winter (Dec-Feb)

B. Summer (jun-Aug)

If an enzyme cannot be produced, then the product of the reaction that the enzyme catalyzes cannot be synthesized and the reactant in that reaction will become highly concentrated. In other words, if a particular chemical cannot produce the appropriate enzyme, that chemical then becomes highly concentrated. Look at Figure 1 to see which enzyme catalyses the reaction of which isocitrate is the reactant: Enzyme 2. Therefore, since yeast that cannot produce Enzyme 2 will have the highest concentration of isocitrate, choice (B) is the correct answer.

B. 5

32.

F. NO CHANGE
G. neighbor; named
H. neighbor named
J. neighbor named,

Correct Answer: H

The underlined portion adds an unnecessary comma between neighbor and named; the comma interrupts the phrase a neighbor named Sasha. If named Sasha were to be omitted from the sentence, the meaning of the sentence would be unclear, so it is incorrect to set it off with commas. For similar reasons, you can eliminate choice (J), which also contains an unnecessary comma. In choice (G), the semicolon is an even more pronounced division of this phrase, so that answer is also incorrect.

According to the information in the passage and Table 2, a strain of yeast that is Cat1+ Cat2- Cat3- Cat4+ CANNOT produce:

F. Enzyme 1 and Enzyme 4.
G. Enzyme 3 and Enzyme 4.
H. Enzyme 2 and Enzyme 3.
J. Enzyme 1 and Enzyme 2.

H. Enzyme 2 and Enzyme 3


The passage tells you that a gene notated with a superscript positive sign is not damaged and that a gene notated with a superscript negative sign is damaged. The passage tells you that if one of the four genes in Table 2 is damaged, then the enzyme it is responsible for cannot be produced. Therefore Cat1+ Cat2- Cat3- Cat4+ means that Enzyme 1 and Enzyme 4 can be produced and Enzyme 2 and Enzyme 3 cannot be produced, so the correct answer is choice (H).

A. NO CHANGE
B. my familys' warnings,
C. my families' warnings
D. my families warnings,

Correct Answer: A

Explanation:

A When you have a singular noun, like family here, use an apostrophe followed by an s. In choice (B), the apostrophe appears in the wrong place, and choices (C) and (D) both change the word to its plural form, so you can eliminate them.

Which of the following statements best describes the relationships between citrate, isocitrate, and α-ketoglutarate as shown in Figure 1?

A. Isocitrate is a product of a reaction of α-ketoglutarate, and α-ketoglutarate is a product of a reaction of citrate.

B.    α-ketoglutarate is a product of a reaction of isocitrate, and isocitrate is a product of a reaction of citrate.

C. α-ketoglutarate is a product of a reaction of citrate, and citrate is a product of a reaction of isocitrate.

D. Citrate is a product of a reaction of isocitrate, and isocitrate is a product of a reaction of α-ketoglutarate.

Correct answer: B

he passage tells you that in the first reaction, citrate is the reactant and isocitrate is the product. Based on this, you know that the reactant is what the arrow points away from and the product is what the arrow points to. Now, take a look at the relationship shown in Figure 1 between the three chemicals in the question (citrate, isocitrate, and α-ketoglutarate). You can see that α-ketoglutarate is a product of a reaction involving isocitrate, and isocitrate is a product of a reaction involving citrate, choice (B).

Why is mark and move a good strategy?

A. It prevents random guessing at the end of time.

D. All of the above.

E. She cannot get the desired score.

B. 93

33.

A. NO CHANGE
B. dense, intricate
C. intricately, dense
D. dense intricacy

Correct Answer: B 



The sentence is incorrect in its original form because intricacy is a noun serving as an adjective (modifying subway routes). Intricate is the adjective form of the word, so choice (B) is the best one. Choice (C) uses the adverb form intricately in place of the adjective, so you can get rid of that answer, and choice (D) doesn't address the part-of-speech problem merely by omitting the comma.

Strain X yeast was most likely unable to synthesize:

F. isocitrate from citrate.
G. α-ketoglutarate from isocitrate.
H. succinyl-CoA from α-ketoglutarate.
J. succinate from succinyl-CoA

G. α-ketoglutarate from isocitrate.


Based on Table 1, you know yeast strain X grows in growth media where α-ketoglutarate, succinyl-CoA, and succinate are added, but cannot grow when citrate or isocitrate are added. This means that the succinate synthesis reaction pathway can happen only if α-ketoglutarate or any reactant after that in the pathway is added, so there is something which prevents the reaction pathway from proceeding from isocitrate to α-ketoglutarate. Therefore, choice (G) is the correct answer.

34.

F. NO CHANGE
G. He had been starting to take
H. His childhood was spent taking
J. He had taken

Correct Answer: J

Explanation:

J This sentence contains a redundant phrase in the underlined portion; During his childhood becomes unnecessary when as a child appears later in the sentence. The best answer choice will eliminate any reference to childhood early in the sentence, which gets rid of choices (F) and (H). Choice (G) uses an incorrect verb tense.

One of the growth media shown in Table 1 was a control that the scientist used to demonstrate that all four strains of yeast had genetic damage that prevented the reactions shown in Figure 1, the reactions which are responsible for the synthesis of succinate. Which growth media was used as a control?

A. BNS
B. BNS + succinate
C. BNS + isocitrate
D. BNS + succinyl-CoA

Correct answer: A


A control is anything in a given experiment that is left alone. Note in Table 1 that BNS appears in all instances, once by itself and then with a number of chemicals added to it. It can be reasonably inferred, then, that the basic nutrition solution (BNS) alone is the control.
