Question

Difficulty: MediumNecessary Assumption

Industry Analyst: The widespread adoption of remote work over the last three years has caused a significant drop in the sales and profitability of formal business attire. Consequently, the recent decline in the overall profit margins of the retail clothing sector is a direct result of this transition to remote work.

For the analyst's conclusion to be properly drawn, it is necessary to assume that the transition to remote work did not generate a surge in casual clothing profits that completely offset the losses from formal business attire.

Answer: Answer

Answer

True
The statement accurately identifies a necessary assumption. By ruling out an offsetting factor (an increase in casual clothing profits), this 'defender' assumption protects the causal link between remote work and the overall sector decline.

Step-by-Step Solution

1
Identify the core argument, distinguishing between the premise and the conclusion.
Premise: Remote work caused a drop in formal attire profits. Conclusion: The overall profit decline in the retail clothing sector is a direct result of remote work.
Understanding the structural relationship between the specific evidence provided and the broader claim is required.
2
Apply the Negation Test to the proposed assumption.
Negated assumption: The transition to remote work DID generate a surge in casual clothing profits that completely offset the losses from formal business attire.
A logically necessary assumption is one that, if proven false, destroys the argument's conclusion.
3
Evaluate the impact of the negated assumption on the conclusion.
If remote work's positive impact on casual clothing profits canceled out its negative impact on formal attire profits, then remote work cannot be the cause of the OVERALL decline in the sector's profit margins.
Since the negated assumption invalidates the conclusion, the original assumption is strictly necessary.

Key Concept

Applying the Negation Test to identify defender assumptions that rule out alternate causes or offsetting factors.
