7. A certain retailer promotes merchandise by using the following policy:
At all times there is either a “manager’s sale” or a “holiday sale” or both going on. All sales are run for exactly one calendar month. In any given month, if a manager wishes to clear out particular line of merchandise, then a managers’ sale is declared. If a holiday falls within the calendar month and there is excess merchandise in the warehouse, then a holiday sale is declared.
However, there is no holiday that falls within the month of August and, in that month, the warehouse never contains excess merchandise.
说明八月不可能有holiday sale
Which one of the following can be concluded from the passage?
(A) If a holiday falls within a given month and there is no extra merchandise in the warehouse that month, then a holiday sale is declared.
(B) If a holiday sale is not being run, then it is the month of August.
因果倒置
(A) If a manger’s sale is being run in some month, then there is no excess merchandise in the warehouse in that month.
没有谈到manager’s sale和excess merchandise的关系
(D) If there is not a manger’s sale being run some month, then there is holiday sale being run in that month.
从开头all times就可以推出来(D)
(E) If there is no excess merchandise in the warehouse, then it is the month of August.
不一定,只能推出八月没有holiday’s sale
