文章:It would be wonderful to observe a singularity (an infinitely dense concentration of matter) and
obtain direct evidence of the undoubtedly bizarre
phenomena that occur near one. Unfortunately, in
most cases a distant observer cannot see the
singularity; outgoing light rays are dragged back by gravity so forcefully that even if they could start out within a few kilometers of the singularity, they would end up in the singularity itself.
题目:
6. Which of the following sentences would most
probably follow the last sentence of the passage?
(A) Thus, a physicist interested in studying
phenomena near singularities would
necessarily hope to find a singularity
with a measurable gravitational field.
(B) Accordingly, physicists to date have
been unable to observe directly any
singularity.
(C) It is specifically this startling phenomenon
that has allowed us to codify the scant
information currently available about
singularities.
(D) Moreover, the existence of this extra-
ordinary phenomenon is implied in the
extensive reports of several physicists.
(E) Although unanticipated, phenomena such
as these are consistent with the structure
of a singularity.
