Question
Statements:All planets are stars.All meteors are planets.No orbit is a star.Conclusions:I. All meteors are stars.II. No planet is an orbit.Conclusion I follows.Conclusion II follows.Either conclusion I or conclusion II follows.Both conclusion I and conclusion II follows.
Solution
Let's analyze the statements and conclusions one by one:
Statements:
- All planets are stars.
- All meteors are planets.
- No orbit is a star.
Conclusions: I. All meteors are stars. II. No planet is an orbit.
From statement 1 and 2, we can infer that all meteors are stars because all meteors are planets and all planets are stars. So, conclusion I follows.
From statement 3, we know that no orbit is a star. However, we don't have any information about the relationship between orbits and planets. Therefore, we cannot conclude that no planet is an orbit. So, conclusion II does not follow.
Therefore, only conclusion I follows.
