Show answer & explanation
Correct answer: C
All stars are moons, so at least some moons are stars; conclusion III follows. Some moons are suns and all suns are satellites, so those suns are satellites as well as moons; conclusion I follows. There is no definite link proving that any star is a satellite, so conclusion II does not follow. Therefore conclusions I and III follow.
