这是题目：
32) The following appeared in a memo from a vice president of Quiot Manufacturing.

During the past year, Quiot Manufacturing had 30 percent more on-the-job accidents than at the nearby Panoply Industries plant, where the work shifts are one hour shorter than ours. Experts say that significant contributing factors in many on-the-job accidents are fatigue and sleep deprivation among workers. Therefore, to reduce the number of on-the-job accidents at Quiot and thereby increase productivity, we should shorten each of our three work shifts by one hour so that employees will get adequate amounts of sleep.

Write a response in which you examine the stated and/or unstated assumptions of the argument. Be sure to explain how the argument depends on these assumptions and what the implications are for the argument if the assumptions prove unwarranted.

题目的instruction说"explain how the argument depends on these assumptions and what the implications are for the argument if the assumptions prove unwarranted"，
1、那到底该怎么解释这个argument是如何依赖于这些假设；
2、又该怎么解释当这些假设不成立时，这个argument的暗示是什么。
（话说那个implications是表示“暗示”吗？我一直没弄懂这个。）
可否就结合这个题目做做简单的点拨，拜托了，先提前谢一声！
