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 every modern-style lamp in the display window is wooden, which of the following must appear in the window?
(A) a retro-style lamp with a grey shade(B) a modern-style lamp with a brown shade
(C) a traditional-style lamp with a white shade
(D) a retro-style ceramic lamp
(E) a traditional-style wooden lamp
Answer and Analysis
The correct response is (D). At least two of the seven lamps are modern in style. (The premise provides that each style is represented at least twice.) Accordingly, if every modern-style lamp in the window is wooden, then at least two of the seven lamps must be wooden. Given that at least four of the lamps are ceramic, you can conclude that at least one of those four ceramic lamps must be retro in style.
