Question

A company switches to a 4-day workweek and observes no productivity drop. Leaders claim the schedule is efficient. Which assumption is needed to support the leaders' claim?

• A. Productivity was measured accurately and comparably before and after the change.
• B. Employees prefer longer weekends due to higher tendency to burnout in longer weeks.
• C. Office rent decreased after the switch since people were only coming in for four days.
• D. Competitors already use a 4-day workweek.

Hint:

For assumption questions, identify what must be true for a conclusion to hold; often it’s a premise that is unstated but necessary.

Answer 1

The Correct Option is A

Step 1: Understand the claim — Leaders assert efficiency based on observed productivity.
Step 2: Identify necessary assumption — For the claim to hold, productivity measurements must be accurate and comparable across both schedules.
Step 3: Evaluate options — Only (a) directly supports the conclusion; other options are irrelevant to productivity measurement.
Step 4: Conclusion — Option (a) is correct.
