[A] The next logical step is to automate the physical process of cutting
the diamond, and Dr Holden seems to have found the ideal partner. He is talking
to Calibrated Diamonds. a company based in Johannesburg, South Africa. about
combining his optimisation techniques with an advanced laser-cutting system.
Traditionally, diamonds are cut and polished using other diamonds. But m recent
years, lasers have been introduced to make rough cuts and m carry, out
"bruting", the bevelling process used to give diamonds their
characteristic sharp-edged shapes. John Bond. the founder of Calibrated
Diamonds, says his laser-cutting method can make much more precise cuts and can
even polish diamonds, though he is reluctant to explain how it works. He
believes that combining his laser-cutting with Dr Holden’s software, and
automating the whole process, could both reduce waste dramatically and cut the
turnaround time from months to days. "Currently, people are losing up

[填空题]The next step ______ (take) when the new program is worked out.
[单项选择](1) Gerald Feinberg, the Columbia University physicist, once went so far as to declare that "everything possible will eventually be accomplished." Well, that of course left only the impossible as the one thing remaining for daring intellectual adventurers to whittle away at Feinberg, for one, thought that "they"d succeed even there."
(2) It was a point worth considering. How many times in the past had certain things been said to be impossible, only to have it turn out shortly thereafter that the item in question had already been done or soon would be. What greater cliche was there in the history of science than the comic litany of false it-couldn"t-be-dones; the infamous case of Auguste Comte saying in 1844 that it would never be known what the stars were made of, followed in a few years by the spectroscope being applied to starlight to reveal the stars" chemical composition; or the case of Lord Rutherford, the man who discovered the structure of the atom, saying in 1933 mat dreams of controlled nuclear fission were "moonshine." And those weren"t even the worst examples. No, the huffiest of all it-couldn"t-be-done claims centered on the notion that human beings could actually fly, either at all, or across long distances, or to the moon, the stars, or wherever else.
(3) There had been so many embarrassments of this type that about mid-century Arthur C. Clarke came out with a guideline for avoiding them, which he termed Clarke"s Law: "When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong."
(4) Still, one had to admit there were lots of things left that were really and truly impossible, even if it took some ingenuity in coming up with a proper list of examples. Such as. "A camel cannot pass through the eye of a needle." (Well, unless of course it was a very large needle.) On "It is impossible for a door to be simultaneously open and closed." (Well, unless of course it was a revolving door.)
(5) Indeed, watertight examples of the really and truly impossible were so exceptionally hard to come by that paradigm cases turned out to be either trivial or absurd. "I know I will never play the piano like Vladimir Horowitz," offered Milton Rothman, a physicist, "no matter how hard I try". Or, from Scott Lankford, a mountaineer "Everest on roller skates."Which of the following statements is TRUE
A. The author uses the case of a camel passing through the eye of a needle to prove his point that there are things impossible to accomplish
B. That a scientist cannot play the piano like one of the best pianists is not a proper illustration to prove that in science there are things impossible to accomplish
C. Scott Lankford challenges the idea that mountaineers can never climb the Everest on roller skates
D. People now laugh at their predecessors for denying the possibility of human flight
