This is an explanation of the first logic game from Section I of LSAT Preptest 30, the December 1999 LSAT.
A bakery will make one delivery consisting six loaves of bread. Each loaf is one of three kinds: oatmeal, rye, or wheat (O, R, W) and each is either sliced or unsliced (s, u). You must use the rules to determine the possible combinations of the bread loaves.
This is a grouping game. Numbers are the most important factor. We need six loaves of bread.
This game is unusual in that we can’t combine many rules to make deductions.
Instead, it’s essential to know the rules, and apply them on the questions. I recommend making a numbered list you can quickly refer to.
- Two kinds of loaves, at least.
- Less than four rye.
- Only sliced wheat.
- One unsliced oatmeal, always.
- The second unsliced loaf is rye.
(On an actual LSAT, I would shorten these. i.e. Unsliced Wheat ➞ Wu)
You’ll notice I changed the wording of the rules. It’s helpful on games to be able to refer to the same idea using different words.
The last rule is the most important. If we have more than one unsliced loaf, we have to have a rye loaf.
There are a couple of possibilities. Either:
- There is only one unsliced loaf (oatmeal) and five sliced loaves. Or,
- There is an unsliced oatmeal and an unsliced rye loaf, along with four loaves that are either sliced or unsliced.
You should try inventing a few scenarios that match the rules, if you’re not totally sure how this game works. It’s very open ended, there are hundreds of scenarios that fit the rules.
