Statements:\nA. Compared to two decades ago, India is producing a larger number of two-wheelers.\nB. The quality of these vehicles has also improved over that period.\n\nConclusions:\nI. India is exporting two-wheelers.\nII. India’s two-wheeler industry has made commendable progress.\n\nWhich conclusion(s) logically follow(s) from the statements above?

Introduction / Context:
This problem tests “statements and conclusions.” We must decide what necessarily follows from two given facts: output of two-wheelers has increased relative to two decades ago, and product quality has also improved. The candidate conclusions mention exports and overall progress of the industry.

Given Data / Assumptions:

• Statement A: Higher production of two-wheelers now than twenty years ago.
• Statement B: Quality of these vehicles has improved compared with the past.
• No explicit mention of exports, trade balances, foreign demand, or export policy.
• “Commendable progress” should be read as a reasonable synthesis of higher volume + better quality.

Concept / Approach:
Only conclusions that are compelled by the premises can be accepted. In logical reasoning, inferring “progress” from simultaneous and sustained improvements in output and quality is reasonable. However, inferring “exports” requires additional facts about international sales that are not provided.

Step-by-Step Solution:

Verification / Alternative check:
Construct two scenarios consistent with A and B: (a) No exports at all; (b) High exports. Both satisfy A and B, showing exports are not entailed. In both scenarios, output and quality gains indicate progress, supporting II.

Why Other Options Are Wrong:

Common Pitfalls:
Equating higher output with exports; assuming facts about foreign markets; rejecting reasonable synthesis (progress) when multiple performance dimensions improve.

Final Answer:
Only Conclusion II can be drawn.
