Difficulty: Easy
Correct Answer: Only conclusion I follows.
Explanation:
Given data
Concept / Approach
 Subset chaining: If Actors ⊆ Girls and Girls ⊆ Beautiful, then Actors ⊆ Beautiful. The statement “Some Girls are Actors” requires existential import for Actors, which is not guaranteed by universal statements alone.
Testing conclusions
 C1: True by transitivity ⇒ Actors ⊆ Beautiful. C2: Not guaranteed; from universals alone, we cannot assert existence of Actors. 
Final Answer
 Only conclusion I follows.
