61 Game 2
Comments
For #11 on answer choice (C) how would it look if the jar was older than the tureen? I'm asking if there are two ways to go about this question - by using the "only if" language or by making the jar and therefore the necklace older than the tureen.
Well, if you make them both older, then you have rule two.
In order to know (C) isn't correct, we need to show that it can be true while the old rule is false.
The point is that the substitution doesn't just allow for the same possibilities as the old rule, but that it requires the same possibilities as the old rule.
For question 11, would you suggest using conditionals to symbolize both types of this rule when seeing if our prior work follows the new rules in the first step for solving substitution questions? Or, would you check the answer choice using only one of the conditional rules and rule both scenarios out in step two of our plan to save time?
