Statement: Sick people need medicine.\nConclusions:\nI) Healthy people do not need medicine.\nII) People keep medicine in their homes.

Introduction / Context:
The premise is a simple necessity claim about sick people. The conclusions attempt to extend it to healthy individuals and to a behavioral habit (home storage), which the premise does not address.

Given Data / Assumptions:

• Sick → need medicine.
• No claims about healthy persons or storage habits are provided.

Concept / Approach:
A statement about one subset (sick people) does not define the complement (healthy people). Some healthy people may take preventive or maintenance medication; some sick people may not store medicine at home. Thus neither I nor II is compelled.

Step-by-Step Solution:
1) Keep scope narrow: “sick people need medicine.”2) Reject extrapolations to healthy individuals (I) and to storage behaviors (II).

Verification / Alternative check:
Counterexamples exist for both I and II, showing they are not necessary conclusions.

Why Other Options Are Wrong:
Choosing I or II imports unstated assumptions.

Common Pitfalls:
Reading necessity for a class as exclusivity for others; inferring habits from needs.

Final Answer:
Neither conclusion follows.
