Difficulty: Easy

Correct Answer: Only conclusion I follows

Introduction / Context:
Another transitivity check with attention to the direction of inclusion.


Given Data / Assumptions:

  • Woman ⊆ Cat.
  • Cat ⊆ Rat.


Concept / Approach:
Chain inclusions to get Woman ⊆ Rat (I true). II reverses inclusion and is not warranted.


Step-by-Step:
1) Woman ⊆ Cat and Cat ⊆ Rat.2) Hence Woman ⊆ Rat (I follows).3) “All rats are women” would require Rat ⊆ Woman, which is not implied.


Verification:
Consider many rats that are not cats; premises do not forbid them.


Final Answer:
Only conclusion I follows.
