LSAT Practice — Analytical Reasoning

Questions 1-4 are based on the following information:

Quantum, a specialty restaurant, is open for business every Monday through Saturday but is closed Sundays. Lunch is the only meal served on Mondays, Tuesdays and Thursdays. Dinner is the only meal served on Wednesdays, Fridays and Saturdays. The restaurant's floors are polished and its plants are watered only on days that Quantum is open for business, according the following schedule:

  • Plants are watered two days each week, but never on consecutive days and never on the same day that floors are polished.
  • Floors are polished on Monday and two other days each week, but never on consecutive days and never on the same day that plants are watered.

Question 4

Assume that floors are polished on consecutive instead of nonconsecutive days but that all other scheduling policies are unchanged. For how many of the six days can it be determined both whether plants are watered and whether floors are polished?

  1. two
  2. three
  3. four
  4. five
  5. six

Explanatory Answer

Given that floors are polished on Monday, based on the question's assumptions floors must also be polished on Tuesday and Wednesday — i.e., on three consecutive days. Since plants are not watered on consecutive days (that policy is unchanged), they must be watered on Thursday and Saturday. Neither task is performed on Friday. The correct response is (E).
