Around 1900, fishermen in the Chesapeake Bay area landed more than seventeen million pounds of shad in a single year, but by 1920, overfishing and the proliferation of milldams and culverts that have blocked shad migrations up their spawning streams had reduced landings to less than four million pounds.
(A) that have blocked shad migrations up their spawning streams had reduced landings to less
(B) that blocked shad from migrating up their spawning streams had reduced landings to less
(C) that blocked shad from migrating up their spawning streams reduced landings to a lower amount
(D) having blocked shad from migrating up their spawning streams reduced landings to less
(E) having blocked shad migrations up their spawning streams had reduced landings to an amount lower

答案B
OG的解释是 from more than...to less than...的平行结构

但是four million pounds还有前面的seventeen million pounds不应该是可数名词吗？可数名词之前不是应该用fewer吗！！！

可数名词	many	few	fewer	fewest	number	numerous	as many as
不可数名词	much	little	less	least	amount	great	equal

这个表有问题吗！！？

T T 自己捞一把诶。

感觉和这个很像，但是这里用less是因为主要的名词是production，是一个不可数名词。上面那题怎么都找不到一个这样的名词，简直纠结
OG16-12 题:
In 1979 lack of rain reduced India’s rice production to about 41million tons, nearly 25 percent less than the 1978 harvest.

我是用排除法做的，顺便问一下为什么要用having been啊！！
