The official explanation provided is as follows:

The argument claims the financial incentives motivated people to change, but no information is provided about people’s prior fitness habits. At the beginning of the year, an employee who already attends a lot of fitness classes would likely choose the variable plan because he or she would save money by doing so. The argument observes a correlation between the variable plan and fitness behavior. The executives concluded that the incentives of the variable plan caused the behavior. This choice weakens the executives’ conclusion by suggesting the opposite causal model: existing fitness behaviors could have caused employees to choose the variable plan in the first place.

Isn't the assumption made that employees who choose the variable plan is based on existing fitness behaviours too far-fetched? GMATNinja

This is a causation vs correlation question.
It could have been the case that majority of gym enthusiasts opted for the variable plan because they knew effective price for them will come around 90$. Not the other way around.

Candy Inc. offers two health insurance plans to its employees. Under the fixed plan, each employee pays $100 per month towards his or her health insurance premium. Under the variable plan, each employee pays $110 per month towards his or her health insurance premium and is entitled to a rebate of $20 in any month he or she attends 10 or more fitness classes at the company gym. Data from the company gym show that over the last year each employee in the variable plan attended an average of 12 fitness classes per month while each employee in the fixed plan attended an average of 6 fitness classes per month. Company executives claim these results demonstrate that even modest financial incentives can motivate people to change their fitness behavior.

Which of the following, if true, most seriously undermines the executives’ reasoning?

(A) Last year, Candy Inc. gave all employees wearable fitness tracking devices, and studies have shown that wearing such devices encourages increased activity levels. This option strengthens the argument. The increase in activity is because of the incentive (wearable fitness tracking device)

(B) Average healthcare costs per person were no lower for employees in the variable plan than for employees in the fixed plan.This option strengthens the argument. Average Healthcare costs are no lower. so this is not a reason to choose either plans.The statement strengthens the conclusion that financial incentive is the reason for change in fitness behavior and more over this option talks about healthcare cost that does not have impact on monthly charge of each plan

(C) Jogging for 30 minutes results in greater cardiovascular fitness benefits than does attending a fitness class. Out of scope

(D) Some employees in the variable plan did not attend enough classes each month to qualify for the rebate. We are not worried on SOME Employees

(E) Employees of Candy Inc. are allowed to select between the fixed and variable plans at the beginning of each year. This Option states that employee choose the plans at the beginning of year.
If I am an employee and fitness person, I will choose variable plan knowing that I will be using the gym regularly. So this weakens the conclusion that the financial incentive is the reason for change in fitness behavior. Moreover the employee can save some more money by not using private gym services

it is totally weird explanation to the ans. ins't it a too much assumption and if this can be assumed then why can't option A be assumed . Option A also provide the opposite causal model.

I eliminated all the options in this as I did not find a suitable weakener. :?

Conclusion- Company executives claim these results demonstrate that even modest financial incentives can motivate people to change their fitness behavior.
I do not agree with OE.

The argument claims the financial incentives motivated people to change, but no information is provided about people’s prior fitness habits.-- Agreed

At the beginning of the year, an employee who already attends a lot of fitness classes would likely choose the variable plan because he or she would save money by doing so.-- But how can we ignore the case that financial incentive motivated people to change their fitness behavior

E. Employees of Candy Inc. are allowed to select between the fixed and variable plans at the beginning of each year-- But it can also mean that financial incentive has motivated people to change their fitness behavior.

Choice (E) says only when employees choose the variable program.

While the fact that they choose the variable program in advance tends to indicate that they plan to attend the classes long before they actually do so, the fact that they choose the plan long before attending the classes is not a clear indicator of their underlying motivation for choosing the variable plan.

In fact, it could very well be the case that they both choose the variable plan and attend the classes partly because of the small financial incentive offered.

So, choice (E) has no effect whatsoever on the strength of the support for the argument’s conclusion, and this question has no correct answer.
Agree . Very unlikely to have such question in actual exam

MartyTargetTestPrep Hello expert, may I ask about A? I think A offers an alternative reason (wearable device) to motivate people to change their fitness behavior, but not the incentive (rebate) motivating people to change their fitness behavior. Can A weaken? Thanks

Why C is out of scope…. Maybe the employees are having physical activity for fitness outside the office space

Very tough question.
Imo E

The conclusion is that the financial incentives led to the more gym attendence.
We have to weaken that.
E says that Folks choose the plan at the starting of the year knowing very well everything.
So folk who choose fixed plan may very well be healthy so they don't want to pay extra for the plan. Other reason my that for variable plan folks want to recover their money in the form of rebate

Option (E) suggests that employees have the choice between the fixed and variable plans at the beginning of each year. If that's the case, it's possible that those who are already motivated to attend fitness classes might opt for the variable plan to take advantage of the rebate. This would mean that the higher attendance in the variable plan might not be due to the financial incentive itself, but rather due to the pre-existing tendencies of the employees who chose that plan.

In other words, if employees who were already more likely to attend fitness classes self-select into the variable plan, then the higher average attendance in the variable plan could be explained by this selection bias, not by the effectiveness of the financial incentive. This would undermine the executives' claim that the financial incentive caused the increase in fitness class attendance.

So, the assumption that people who are inclined to attend more fitness classes might choose the variable plan is based on the idea that individuals are likely to choose the plan that aligns with their behavior or intentions, which is a common consideration in situations where individuals have the option to select between different plans or incentives.
