Q01Practice Question · অনুশীলন
A library argues: “Extending our opening hours into the evening will increase visits.” Which assumption is necessary for that prediction?
Learn the reasoning, not just the answer.
A little clarity goes a long way.
- A (All current visitors will stop reading at home.):The prediction does not require all visitors to change their reading habits; this is far stronger than necessary.
- B (The library will buy no new books.):Book purchases are not required or excluded by the argument about opening hours.
- C (Some people want to visit during the added hours and their visits will not merely replace existing visits.):Without some additional demand that produces net new visits, longer hours alone do not imply an increase in total visits.
- D (Every resident already owns a library card.):Potential new visitors could obtain cards later, so universal current membership is unnecessary.
KEY TAKEAWAY
Negate a proposed necessary assumption: if the prediction then loses its basis, the assumption is relevant.
