being,  and their   significance.   Choice  (A) is  incorrect   because very    little  is  discussed   in  the
passage  regarding   sanitation.     Choice  (B)     is  too     limited     in  scope,  and     (C)     is  incorrect
because religion    is  never   discussed   in  the passage.    Choice  (D) best    expresses   the overall
idea    of  the passage and is  the correct answer.
 - B The first sentence draws a contrast between Greek and Roman architecture, so use POE to 
 find an answer choice that reflects this. Eliminate (A) because the passage doesn’t suggest
 that Roman architecture improved upon Greek architecture. Choice (B) works because new
 trends shows how Roman architecture differed from Greek architecture; keep it. Choice (C)
 is too extreme because nothing is proven, so eliminate it. Choice (D) is incorrect because
 religion is not discussed much in the passage, so eliminate (D). Choice (B) is correct.
 
 - B Cross out omnipresent and use the context to find an acceptable replacement. The curves 
 are also described as dominating, and later in the paragraph the world the architects
 created is described as one that was transformed into a new curvesomeness. This suggests
 that the curves are a characterizing feature, so find the choice that matches these
 descriptions. Choice (B) is a match, since pervasive means “everywhere.” Choice (A) is
 too limited, and (C) is a trap because the ceilings, not the curves, reached up to the
 heavens. Choice (D) is incorrect because imposing means “impressive in appearance.”
 Choice (B) is correct.
 
 - C The second paragraph states that this grand Roman innovation in architecture would be 
 accomplished in two centuries as the essential ingredient, concrete, was perfected
 gradually by trial and error. Choice (C) matches this information. The other answer
 choices pertain to the passage, but since the question is asking for the critical component,
 (C) is the correct answer.
 
 - B Lines 15–18 identify concrete as the essential ingredient in Roman innovation and state that 
 it was perfected gradually by trial and error. Choice (B) is correct.
 
 - A The third paragraph states that the new architectural creations arose from the needs of 
 these Roman cities, so the correct answer will reflect this idea. Choice (A) is a good match
 because the needs of the new Roman cities are what prompted the differences between
 Greek and Roman architecture discussed in the first paragraph. Choice (B) doesn’t work
 because the passage does not reinforce this contrast but rather explains it. Choice (C) is
 alluded to at the end of the paragraph, but it is hardly the primary purpose. The author does
 not dismiss anything, so (D) is incorrect as well. Choice (A) is the correct answer.
 
 - A The first sentence of this paragraph describes the grand Stabian baths and how some of 
 their features would show up in the Pantheon three centuries later. Therefore, replace
 anticipated with something that means “indicated” or “suggested.” Choice (A) is the
 closest to this meaning and the correct answer.
 
 - C Use POE to find an answer choice consistent with what is in the last paragraph. The 
 paragraph details the variously heated and cooled spaces within the baths, which supports
 (C), as the baths were a critical part of Roman life and offered the opportunity to
