LSAT Practice Questions — Analytical Reasoning
Questions 1-3 are based on the following information:
Seven lamps are featured in a furniture store's display window. Each lamp is either ceramic or wooden and is paired with either a brown, white or grey shade. The display includes at least two lamps in each of three styles: traditional, modern and retro.
- At least four of the lamps are ceramic.
- If a lamp has a white shade, the lamp is ceramic.
- No wooden lamp is paired with a brown shade.
If two and only two ceramic lamps are paired with shades of the same color, which of the following must be true?
(A) One of the seven lamps has a brown shade.(B) Two of the seven lamps have white shades.
(C) Three of the seven lamps are wooden.
(D) Four of the seven lamps have grey shades.
(E) Five of the seven lamps are ceramic.
Answer and Analysis
The correct response is (C). We know that at least four of the seven lamps are ceramic. Assuming that two and only two such lamps have shades of the same color, the total number of ceramic lamps is limited to four (only three shade colors are available). Under this assumption, then, exactly three of the seven lamps would be wooden.
