QUESTION TEXT: John works five days each week except…
QUESTION TYPE: Necessary Assumption
CONCLUSION: Last week, John must have worked as an insurance agent on Monday, Tuesday, Wednesday and Thursday.
REASONING: John works four days a week as an insurance agent and on Fridays he works as a Blacksmith. John works five days per week on weeks when there is no holiday and he takes no vacation. This week there were no holidays and John took no vacation.
ANALYSIS: The argument is assuming that John didn’t work on the weekend.
___________
- This is irrelevant. John took no vacation this week.
- The stimulus doesn’t say whether John has to work full days or not.
- There are no vacations or holidays last week. Irrelevant.
- CORRECT. The argument didn’t say that John only works weekdays. We can only conclude that John worked Mon, Tues, Wed and Thursday if he didn’t work on the weekend last week.
- The argument never said that John works as a blacksmith only on Fridays. He could also work as a blacksmith on Tuesdays, for example, after he leaves work at the insurance office.
Every condition is met, John would still be working five days each week, four in an insurance office, and as a blacksmith on Fridays.
