The Gym has a problem: Basic membership got too good (better equipment), so nobody wants to pay for Elite anymore.
The Plan: Make Basic membership annoying again (by restricting convenient times).
The Goal: Force people to Upgrade to Elite.
IMO The correct answer is (D).
Here is the breakdown:
The Logic of the Plan:
The Lever: We will take away "Convenient Time Slots" from Basic members.
The Expected Result: Basic members will value those time slots so much that they will agree to pay the extra money for Elite status.
The Necessary Assumption (The Bridge):
For this to work, the gym must assume that the "Pain of Inconvenience" is greater than the "Pain of Paying More."
If the members look at the restriction and say, "Eh, I'll just go at 9 PM to save $50," then the plan fails. The restriction must be a strong enough motivator to force the behavior change.
Option (D) states exactly this:
(D) Restricting access during convenient time slots will give basic members enough reason to upgrade.
The Negation Test:
Negation: Restricting access will NOT give members enough reason to upgrade (i.e., they will just accept the inconvenient times or quit).
Result: If it's not enough reason, they won't upgrade. The plan to "prevent the reduction in upgrades" fails immediately.
Why the others are incorrect
(A) Elite memberships are currently too expensive:
If this were true, the plan would definitely fail. (If they can't afford it, restricting times won't magically make them rich). The argument assumes the opposite: that they can afford it. Since (A) says they can't, it's a weakener, not an assumption.
(B) Prefer inconvenient slots anyway:
If most members like going at 2 AM (inconvenient), then restricting the 6 PM (convenient) slot does nothing. They wouldn't notice. They wouldn't upgrade. The plan would fail. The argument assumes this is False (that they do want convenient times). Since (B) says it is True, it creates a failure scenario.
(C) Will not switch to another gym:
While important, it is not as fundamental as (D).
Scenario: Even if they don't switch gyms (maybe this is the only gym in town), they might just stay Basic and work out late. If they do that, the gym fails to get the upgrades.
(D) is necessary because it forces the Upgrade. (C) only prevents the Exit, but preventing the exit doesn't guarantee the upgrade.
(E) Other gyms/Comparable equipment:
This relates to (C). Even if other gyms have better equipment, if the restriction at PulsePoint isn't annoying enough (D), people will just stay Basic at PulsePoint. The internal logic of the incentive matters more than the external market here.
Bunuel
PulsePoint Gym recently upgraded the equipment in the basic-members area so that it now matches many of the features previously available only in the elite zone. This makes the basic membership far more attractive and risks reducing upgrades to elite memberships. To prevent that, PulsePoint plans to restrict basic members from using the new equipment during the most convenient time slots, even though the facility has enough capacity to allow it.
Which of the following is an assumption on which the plan depends?
(A) Elite memberships are currently too expensive for most basic members.
(B) Most basic members prefer to work out during inconvenient time slots anyway.
(C) Basic members will not respond to the restrictions by switching to another gym.
(D) Restricting access during convenient time slots will give basic members enough reason to upgrade.
(E) Other gyms in the area do not offer comparable equipment.
