?Researchers agreed that the study of new treatments for heart attack patients was extremely important but more research was needed to determine that balloon angioplasty preceded with ultrasound was or was not any better for heart attack patients than the balloon procedure by itself.
?
A.A。 more research was needed to determine that balloon angioplasty preceded with ultrasound was or was not any better for heart attack patients than
B.B. more research was needed for determining whether or not balloon angioplasty preceded by ultrasound is any better for heart attack patients than is
C.C. that more research was needed to determine whether balloon angioplasty preceded by ultrasound is any better for heart attack patients than
D.D. that more research was needed to determine that balloon angioplasty preceded with ultrasound was any better for heart attack patients than
E.E. that more research was needed for determining that balloon angioplasty preceded by ultrasound is or is not any better for heart attack patients than is
答案是C。可是C里面whether后面的从句用的是is。这里并不是什么不可改变的事实，数据，为什么可以用is呢？

科学或通常事件的讨论，与发生时间无关系的事情，被称为general definitions. 应该用simple present.

但是，这只是researchers的讨论，并不一定是定理的。或者is和was都可以？我总是感觉is太过于牵强，不过只要is不是完全错的，就可以选了，其他的错的更厉害。

from RON

if you're talking about GENERAL TRUTHS, then youuse the present tense (regardless of the tense(s) in the surroundingcontext).
the only exception is for things that WERE general truths, but are no longer.in that case, of course, you'd use the past tense. (or, for things that WILL BEgeneral truths but aren't yet, you should use the future tense.)
e.g.
in 1628, william harvey discovered that human blood circulatesthrough the arteries and veins.
CORRECT
"discovered" --> past tense (since this happened in 1628)
"circulates" --> present tense (since this is a GENERAL TRUTH)

in 1628, william harvey discovered that human blood circulatedthrough the arteries and veins.
INCORRECT
this implies that blood doesn't circulate anymore in today's humans.

--

in this case, the principle in question (whether X isbetter than Y) is a general truth that isn't subject to a timeframe. therefore,it should be in the present tense.

我觉得讨论的是balloon angioplasty preceded with ultrasound 到底是不是比b a本身对于治疗心脏病人更好需要more research证明好不好的这个事实而不是曾经好现在不好

I still think "is" and "was" both work here, as the "a general truth" should be justified by common sense, to which the discussion among some researchers might not lend enough support.

同意LS，我觉得这里用时态作为split点不好，考试的时候你对某个东西到底是不是general definitions的判断一定很准吗？这本来就是众说纷纭的东西，所以除了显而易见的general definitions，比如地球绕着太阳转，其它的应该去找更明显的split点。。。。在这个语境下，C中的whether显然比D中的that好~ 而且我甚至觉得这里根本就不能用that，因为是要判断二者到底哪一个更好，不是要决定一个一定比另一个好。。。

D determine that..."表示"确定/判定"己有结果，要用determine whether来表示结果未确定；preceded with错误；determine的内容发生在主句agree之后，所以应该用agree向后推移的时态：一般现在时is，而不能用一般过去时was。
