A. tested that could eventually propel aircraft anywhere in the world within two hours or help
B. tested that could eventually have the capability of propelling aircraft anywhere in the world within two hours or to help
C. tested, eventually able to propel aircraft anywhere in the world within two hours, or helping

这道究竟是A还是E呢？？ E中的the capability to do与could意思重复么？A错是否因为that必须要紧跟修饰的名词呢？？
Q8:
A new hair-growing drug is being sold for three times the price, per milligram, as the drug’s maker charges for another product with the same active ingredient.
as
than
that
of what
at which
这道究竟时C还是D呢？？
我的理解是： 3 times the price of what the drug’s maker charges for. What是of的宾语，而现在句子中已经有了“another product”，所以和what的作用是重叠的。 |
