Statement:\nMr. X is planning to transform his old sweet shop into a fast-food joint.\n\nConclusions:\nI. Fast food is much more in demand than sweets.\nII. Diabetes is on the rise.

Introduction / Context:
The statement reports a business decision: converting a sweet shop into a fast-food outlet. We must not project market wisdom or public health trends unless the statement itself provides those links.

Given Data / Assumptions:

• One shop owner's plan to change format.
• No explicit market data or health statistics are given.

Concept / Approach:
Conclusion I generalizes demand (“much more in demand than sweets”). The decision could be driven by location, margins, competition, or personal preference; the statement does not justify a market-wide demand claim. Conclusion II speculates about diabetes trends; nothing in the statement references health concerns as a motive. Therefore neither conclusion follows.

Step-by-Step Solution:
1) From one decision you cannot infer a general demand hierarchy → I does not follow.2) No health rationale is provided → II does not follow.

Verification / Alternative check:
The conversion could even be experimental or lease-driven; either way, the premises do not entail I or II.

Why Other Options Are Wrong:
“Either/Both” assume causal links not in evidence; “Only I/Only II” likewise over-interpret.

Common Pitfalls:
Attributing market/health reasons to a decision without textual support.

Final Answer:
If neither I nor II follows.
