LR Drill Set 1, Question 5

What we’re looking for

Working the answers

• A
  Correct

  Items bought at the store match load-bearing supports. Being returnable matches being essential. Pat's items match the walls. Everything bought at the store must be returnable, but some of Pat's items aren't returnable. Those particular items therefore weren't bought there. This is the same valid use of a rule: an item that lacks a required property cannot belong to the group that requires it.

• B

  This links two rules forward. Sandstone belongs to the sedimentary group, and everything in that group was formed by deposited particles, so sandstone was formed that way. That reasoning works, but it doesn't match ours. No separate group is shown to lack the required property. To match, we would need something like: some volcanic rocks aren't sedimentary, so those rocks aren't sandstone.

• C

  The second sentence gives us people who have the required properties, not people who lack them. Some licensed and bonded people aren't trustworthy, but those people might not be officers of this group. All the group's officers could be trustworthy while some other licensed, bonded people aren't. The original rules particular walls out of a group; C tries to transfer a fact about some members of a broader group to a narrower group.

• D

  This rules out the wrong property first. The lace items aren't slipcovers, whereas our walls aren't essential. Knowing that something isn't a slipcover doesn't tell us it isn't protective: a blanket could protect furniture too. To match, D would need to say some lace items aren't protective and therefore aren't slipcovers.

• E

  Some entertainment isn't worth serious attention, but all of those examples could be things other than plays. The answer never establishes that any plays belong to that disappointing group. To match the original, we would need some things worthy of attention that aren't entertainment, followed by the conclusion that those things aren't plays.
