argument里面那个alternative explanations这个instruction。。。

argument里面这个instruction该如何破题呢？！
Write a response in which you discuss one or more alternative explanations
that could rival the proposed explanation and explain how your explanation(s)
can plausibly account for the facts presented in the argument.
跪求各位！ the proposed explanation 应该指的是文中的总解释，那么写作中写的 alternative explanations 应该针对原题中的总解释呢还是 某一个fact或者某一个evidence的alternative explanation呢？

shinian1987前辈在上面这个帖子里面提到：
“第104题（与32题稍微有点变动）：
Instruction：Write a response in which you discuss one or more alternative explanations that could rival the proposed explanation and explain how your explanation(s) can plausibly account for the facts presented in the argument.
提纲：1：事实.workers at our newly opened factory reported 30 percent more on-the-job accidents than workers at nearby Panoply Industries. 文中解释，员工疲劳和睡眠不足。其他解释：新开的厂可能招的是新员工，员工的操作熟练程度不够，公司的设备维护不到位，员工的生产安全意识不够。
2：事实，Panoply's superior safety record，文中解释：shorter work shifts, 其他解释：P公司的员工比较有经验，操作熟练，P公司的生产自动化程度高，很多比较危险的工作场合由机器人代替。”

那么，根据shinian1987前辈的意思就是 针对 fact和evidence的解释啦？
