QUESTION TEXT: All of the cargo ships of the Blue Star Line are over…
QUESTION TYPE: Must be True
FACTS:
- Blue star ships are over 100 meters if they are cargo ships and under 100 if they are passenger ships. Most of the ships were built before 1980.
- All of the Gold Star ships are less than 100 meters and were built after 1980.
- Ships over 100 meters can’t dock at Port Tropica.
- S.S. Coral is docked at Port Tropica and is a cargo ship.
ANALYSIS: Only Gold Star has cargo ships shorter than 100 meters. So the S.S. Coral must be a Gold Star Ship. Since that’s the case, it must also have been built after 1980.
___________
- CORRECT. This has to be true because the Coral is a Gold Star ship. That has to be true because only Gold Star cargo ships are less than 100 meters long.
- We know this is false, since Blue Star cargo ships are over 100 meters.
- This doesn’t have to be true. We only know that Port Tropica has one cargo ship docked at it. There could be passenger ships too.
- We only know that cargo ships from the Blue Star Line can’t go to Port Tropica. Passenger ships might dock there.
- Not necessarily. We only know that most Blue Star ships were built before 1980. But some could be quite recent.
