is precisely what scientists want to measure (not a limitation), and (E) is a
distortion—it is
not
preferable to capture only average levels. This goes
against the main point of both paragraphs.

1st and 3rd only.
According to the second paragraph, flow cytometry
and RNA FISH are examples of “single-cell measurement technology,” so the
first statement is true. Much of the wording in the second statement—“it is
impossible to distinguish a uniform population of cells expressing
intermediate quantities of a molecule”—is lifted from a sentence in the first
paragraph, talking about classical methods—not the newer, single-celled
measurement technologies. Finally, the second paragraph states that flow
cytometry and RNA FISH have “made it possible to capture … the
distribution of the molecule’s expression within the population,” which is a
good match for the wording in the third statement.

(C).
This question asks for the choice
not
mentioned in the passage. The
first paragraph states that Portugal “once mined Angola for slaves and raw
material,” so choices (A) and (B) are out. The beginning of the passage
concerns Portugal taking over Angola over a period beginning in the 16th
century and culminating in the 1920s, so eliminate choice (D). The passage
refers to “Angolan independence in 1975”—since that date is during the 20th
century, choice (E) is out. The passage says that a “civil war” in Angola lasted
until 2002, not a war against the Portuguese, so choice (C) is the answer.

(B).
The “grand stroke of irony” the author refers to is Angola helping
Portugal. Why is this ironic? Because, as stated in the first paragraph, “The
country that once mined Angola for slaves and raw material is now virtually
helpless.” Choice (B) is the best match. Choices (A) and (E) are not ironic.
While choices (C) and (D) do present some kind of contrast, they are not the
“stroke of irony” to which the author refers.
126.
(E).
According to the third paragraph, Gage’s physical injury affected his
personality. The part of his brain that was damaged is now known to be
related to morality, and Gage “literally lost one (or more) of the modules in
his modular brain system.” Choice (E) is a good match. Choice (A) is the
opposite of what is being argued. Choice (B) is not indicated by the passage.
Choice (C) may be true but is not the reason the author presented the
example. Choice (D) relates to the previous paragraph, not to Phineas Gage.
