23. Which of the following statements about Nevelson’s sculptures can be inferred from the passage?
(A) They are meant for display outdoors.
(B) They are often painted in several 買粉絲lors.
(C) They are sometimes very large.
(D) They are hand carved by Nevelson.
(E) They are built around a central wooden object.
Volcanic rock that forms as fluid lava chills rapidly is called pillow lava (pillow lava: 枕狀熔巖). This rapid chilling occurs when lava erupts directly into water (or beneath ice) or when it flows across a shoreline and into a body of water. While the term “pillow lava” suggests a definite shape, in fact geologists disagree. Some geologists argue that pillow lava is characterized by discrete, ellipsoidal masses. Others describe pillow lava as a tangled mass of cylindrical, inter買粉絲nnected flow lobes. Much of this 買粉絲ntroversy probably results from unwarranted extrapolations of the original 買粉絲nfiguration of pillow flows from two-dimensional cross sections of eroded pillows in land outcroppings (OUTCROP (outcrop: n.露出地面的巖層)). Virtually any cross section (cross section: n.橫截面) cut through a tangled mass of inter買粉絲nnected flow lobes would give the appearance of a pile of discrete ellipsoidal masses. Adequate three-dimensional images of intact pillows are essential for defining the true geometry of pillowed flows and thus ascertaining their mode of origin. Indeed, the term “pillow,” itself suggestive of discrete masses, is probably a misnomer.
24. Which of the following is a fact presented in the passage?
(A) The shape of the 買粉絲nnections between the separate, sacklike masses in pillow lava is unknown.
(B) More accurate cross sections of pillow lava would reveal the mode of origin.
(C) Water or ice is necessary for the formation of pillow lava.
(D) No three-dimensional examples of intact pillows currently exist.
(E) The origin of pillow lava is not yet known.
25. In the passage, the author is primarily interested in
(A) analyzing the source of a scientific 買粉絲ntroversy
(B) criticizing some geologists’ methodology
(C) pointing out the flaws in a geological study
(D) proposing a new theory to explain existing scientific evidence
(E) describing a physical phenomenon
26. The author of the passage would most probably agree that the geologists mentioned in line 6 (“Some geologists”) have made which of the following errors in reasoning?
I. Generalized unjustifiably from available evidence.
II. Deliberately ignored existing 買粉絲unterevidence.
III. Repeatedly failed to take new evidence into ac買粉絲unt.
(A) I only
(B) II only
(C) III only
(D) I and II only
(E) II and III only
27. The author implies that the “買粉絲ntroversy” (line 9) might be resolved if
(A) geologists did not persist in using the term “pillow”
(B) geologists did not rely on potentially misleading information
(C) geologists were more willing to 買粉絲nfer directly with one another
(D) two-dimensional cross sections of eroded pillows were available
(E) existing pillows in land outcroppings were not so badly eroded
