Q) The higher productivity rate of some Japanese companies relative to comparable US companies is due not to
their faster production lines, which are in fact slower in the Japanese companies, but to a greater amount of engineers and equipment per production worker.
(A) their faster production lines,
which are in fact slower in the Japanese companies, but to a greater amount of engineers and
(B) their faster production lines,
since they are in fact slower in the Japanese companies, but to a greater amount of engineers and
(C) faster production lines,
which are in fact slower in the Japanese companies, but to a greater amount of engineers and more
(D) the greater speed of their production lines,
since they are in fact slower in the Japanese companies, but to a greater amount of engineers and
(E) ) the greater speed of their production lines,
since production lines are in fact slower in the Japanese companies, but to a greater amount of engineers and more
What's wrong with c?
1. are " faster production lines" and " the greater speed of their productin lines" different in terms of meaning?
2. I think that "since production lines~"in e makes more sense than "which are in fact~" in c, but I am not sure
about "their" in e. In fact, this is the reason that I ruled out e.
Isn't it possible that "their" refers to either Japanese companies or American companies?
Am I thinking too much??
