Analyze Logical Inference: Rajan & Sajan Scenario

This question asks to identify the logically valid inference from the given scenario involving Rajan and Sajan's project work.

Scenario Breakdown

• Rajan's unhappiness is noted when Sajan chooses to work independently.
• Sajan clarifies his choice by stating a preference for working alone.

Evaluating Inferences

We need to find which statement is directly supported by Rajan's reaction and Sajan's explanation:

• Option 1: Rajan's unhappiness about Sajan working alone doesn't necessarily mean Rajan exclusively prefers group work. His unhappiness relates specifically to Sajan's decision.
• Option 2: There is no information suggesting Rajan and Sajan were placed in a group unwillingly.
• Option 3: Sajan's statement highlights his preference for independent work. This contradicts the idea that he was giving in to Rajan.
• Option 4: Rajan's unhappiness is a reaction to Sajan working alone. This reaction strongly implies Rajan had expected or believed they would work together. Sajan's explanation addresses this perceived deviation from their presumed plan.

Valid Inference Conclusion

Rajan's emotional response (unhappiness) stems from a mismatch between his expectation and the reality of Sajan working solo. Therefore, the most logical inference is that Rajan anticipated a collaborative effort.
