Because ethylene dibromide, a chemical used to fumigate grain, was blamed for the high rate of nerve damage suffered by people who work in grain-processing plants, many such plants switched to other chemical fumigants two years ago.  Since then, however, the percentage of workers at these plants who were newly diagnosed with nerve damage has not dropped significantly.  Therefore, either ethylene dibromide was wrongly blamed or else the new chemicals also cause nerve damage.
Which of the following is an assumption on which the argument depends?

既然2001年都用了过去时proved，那么它之前的1992年用过去的过去had 可以吖，为啥AB错？还有其它的点排除吗？
