Hi
MartyMurray,
Can you please let me know why 1 is current issue of magazine & 2 is past issue of magazine?
And it is not the other way that is 1 as past issue of magazine & 2 as current issue of magazine?
Thanks in advance!
Let me try to address it.
1. We're told:
Quote:
All of those (the orders) that include a past issue of the magazine also include the current issue of the magazine.
So, can an order contain
a. only a past issue of the magazine?
No. Because all orders that include a past issue also include the current issue.
b. only a current issue of the magazine?
Yes. All orders that include a past issue will also include the current issue. But, an order with the current issue could be made without including a past issue.
Now, on to the statement.
Quote:
Statement: For the orders placed to the company today, if one employee were to package all of the orders that include a ___1___, that employee would also package all of the orders that include a ___2___.
First off, the statement is not:
If an order includes ___1____, the order would also include ___2___.The statement is not about an individual order. We need to figure out what else we can state about an employee who has packaged all of the orders that include a particular item (1).
Are the following orders valid? (For simplicity, I am going to ignore all the other items and focus only on magazines.)
Order 1: A past and the current issue of the magazine
Order 2: Only the current issue of the magazine
Order 3: Only a past issue of the magazine
Oder 1 is valid. An order can include both kinds of issues.
Order 2 is valid. An order can include only the current issue.
Order 3 is not valid. All orders that include a past issue will also include the current issue.
Now, say an employee were to package all orders that include a
past issue of the magazine.
Can we say that the employee would also package all orders that include
the current issue of the magazine?
No.
E.g. an employee may package order 1 (past and current issues both). But a different employee may package order 2 (only current issue).
But, say an employee were to package all orders that include a
current issue of the magazine.
Can we say that the employee would also package all orders that include a
past issue of the magazine?
Yes.
The orders that include a current issue of the magazine would be a superset of the orders that include a past issue of the magazine.
So, if an employee were to package all the current issue orders, the employee would also certainly package all the past issue orders.
Put another way, if an employee were to package the superset, the employee would also certainly have packaged the subset.
Answer:
1: Current issue of the magazine
2: Past issue of the magazine
