Using technology as new as space-age fabrics and as ordinary as common dry-cleaning chemicals,
scientists and historians, in their attempt at cleaning and preserving the American flag that flew over
Fort McHenry in Baltimore
in 1814, are hoping that it will then last another 200 years.
(A) and as ordinary as common dry-cleaning chemicals, scientists and historians, in their attempt at

(B) and as ordinary as common dry-cleaning chemicals, scientists and historians are attempting to
clean and preserve the American flag that flew over Fort McHenry

解释说A错误是因为in their attempt at cleaning…名词表达方式不及动词attempt有效。正选B
A和B相比最多只能说是不好，但是B和原句意思不一样，完全改变意思，这也可以？
还有个说法说A这么用的话，后面的IT就会指代不明，为什么了，我感觉挺明白的~(A) and as ordinary as common dry-cleaning chemicals, scientists and historians, in their attempt at
