Assume the statements are true.

Statements: No cloud is a star. Some stars are moons. All moons are planets.

Conclusions:

I. All moons being clouds is a possibility.

II. Some planets being clouds is a possibility.

Explanation

1. 01

   Some moons are stars, and no star is a cloud, so those moons can never be clouds. 'All moons being clouds' is impossible: I does not follow.

2. 02

   Planets that are not moons (or moons that are not stars) are unrestricted, so a picture where some planets are clouds obeys every statement. II follows.

3. 03

   Only II follows.
