- C and E What the scientist encounters is based on the “divergent opinions in
the field.” If there are divergent opinions, then his theory would most likely
encounter resistance and criticism. - A and E The word in the blank describes what the Internet has done to
people’s attention spans. The phrase after the colon provides context for
this word by indicating that people will not view a page unless it provides
“immediate stimulation.” If people need “immediate stimulation,” then their
attention spans must have suffered a diminishment. Of the choices, the words
closest in meaning to “diminishment” are a decrease and an attenuation. - A and E The fact that people seek psychotherapy contrasts with their views of
it. Among the choices, the words that best express a contrast are skepticism of
and aversion toward. - A The author mentons the fact that Navajo “has no alphabet or symbols”
in support of the larger claim that “Johnston believed Navajo answered
the military requirement for an undecipherable code because Navajo is an
unwritten language of extreme complexity.” The lack of alphabet or symbols is
one example of this complexity. - D The purpose of the passage is to explain why Johnston recommended using
Navajo for secure communications. - Sentence 9: Johnston staged tests under simulated combat conditions,
demonstrating that Navajos could encode, transmit and decode a three-line
English message in 20 seconds. This is the only sentence mentioning a study
conducted to demonstrate the benefits of using Navajo. - D To weaken the argument, we should show that smoking leads to insomnia
or that some third factor leads to both. Choice D suggests that the symptoms
of smoking lead to insomnia. - B The first sentence of the passage states that the artists had to rely on other
means “in part because of its ban on figural representation.” - B In the first sentence, the author introduces “geometric patterns for
ornamentation” as one of the examples “of art that have been seen since the
seventh century.” This statement implies that these patterns did not exist
before the seventh century.
