It is the powerful compound capsaicin that makes a chili pepper hot; a single drop that has no taste and odor is capable of detection by humans at one part per million.
A. a single drop that has no taste and odor is capable of detection
B. a single drop is detectable, though without taste and odor,
C. a single tasteless and odorless drop can be detected
D. single tasteless and odorless drops are capable of detection
E. single drops that have no taste or odor can be detectable

答案：C

求问，B为什么不对啊，有解释说：
Placing the modifier though without taste and odor between detectable and by humans introduces confusion and ambiguity about who can detect a single drop of capsaicin.
但我并不觉得这会造成会谁detect的困扰啊。/(ㄒoㄒ)/~~
另外，这句话的意思是什么呢？其实有点读不懂后半句，by humans at one part per million是什么意思呢？求NN解释

modifier 的金科玉律是修饰语要尽可能的靠经被修饰的部分

B 选项的这个结构让人觉得 without 修饰的是 Detectable; 而原句的intended meaning 是要修饰drop 的
其次， without taste and odor, 用法是错的，以下引用RON 的解释：

* it's nonsense to use a negative (such as not, without, few, etc.) with "x AND y", because we don't have any idea what that means.
e.g.,
i have no work and no money. --> clear meaning: i have neither of these things.
if i have no work or no money, my uncle can help me. --> clear meaning: if i have either #1 or #2, he can help.
i have no work or money. --> clear meaning: same as the first sentence.
BUT
i have no work and money. --> what does this mean? we don't know. it's basically a nonsense statement.

最后 one part per million 是百万分之一的意思
