An experiment conducted aboard Space Lab in 1983 was the first attempt to grow protein crystals in the low-gravity environment of space. That experiment is still cited as evidence that growing crystals in microgravity can increase crystal size: the authors reported that they grew lysozyme protein crystals 1,000 times larger than crystals grown in the same device on Earth. Unfortunately, the authors did not point out that their crystals were no larger than the average crystal grown using other, more standard techniques in an Earth laboratory. No research has yet produced results that could justify the enormous costs of producing crystals on a large scale in space. To get an unbiased view of the usefulness of microgravity crystal growth, crystals grown in space must be compared with the best crystals that have been grown with standard techniques on Earth.

1.It can be inferred from the passage that the author would find the Space Lab experiment more impressive if which of the following were true?
(A) The results of the Space Lab experiment could be
replicated in producing other kinds of crystals in
addition to lysozyme protein.
(B) The device used in the experiment produced larger
crystals on Earth than it did in space.
(C) The size of the crystals produced in the experiment
exceeded the size of crystals grown in
Earth laboratories using standard techniques.
(D)The cost of producing the crystals in space exceeded
that of producing them using standard laboratory
techniques.
(E) The standard techniques used in Earth laboratories
were modified in the Space Lab experiment due to the effects of microgravity.

我知道定位在这啊Unfortunately, the authors did not point out that their crystals were no larger than the average crystal grown using other, more standard techniques in an Earth laboratory.但是这句话取非不是就把前面的did not point去掉吗。。那不是no larger了这样和答案c相反啊求解@@@

是C啊，LZ，做reading要看上下文的，全文看完就知道 Unfortunately, the authors did not point out that their crystals were no larger than the average crystal grown using other, more standard techniques in an Earth laboratory 指的是作者迴避了宇宙生長的晶體其實並不比地球上用最好的技術生長的大這個事實。

我定位在最後一句的，To get an unbiased view of the usefulness of microgravity crystal growth, crystals grown in space must be compared with the best crystals that have been grown with standard techniques on Earth. 看這句就知道你所定位那句的語氣了。

不知道為什麼大家很喜歡“取非”這個方法，使用技巧應該建立在讀懂大致內容和語氣的基礎上的
