Let's approach this Identify the Assumption question step-by-step:
1. First, let's break down the argument:
* Premise: The city plans to remove free parking spaces downtown to encourage public transportation use.
* Premise: Drivers who currently park for free would have to pay for parking.
* Conclusion: Many downtown businesses are concerned that their customer traffic would decrease significantly, leading to reduced sales.
2. We need to identify what assumption is necessary for this conclusion to be valid.
3. Let's evaluate each option:
A. Other incentives or conveniences are insufficient to keep the same number of customers visiting downtown businesses.
* This is a strong contender. It assumes that without free parking, other factors won't be enough to maintain customer traffic.
B. Downtown businesses depend solely on customers who drive and park downtown for the majority of their sales.
* This is too extreme. The argument doesn't assume that businesses depend "solely" on drivers, just that a significant portion of customers drive.
C. The primary reason for removing free parking is to generate additional revenue from paid parking spaces.
* This contradicts the given information, which states the reason is to encourage public transportation use.
D. Customers who currently use the free parking are likely to visit downtown businesses less often if they have to pay for parking.
* This is the core assumption of the argument. It directly links the removal of free parking to decreased customer traffic.
E. The city should provide additional public transportation options to compensate for the removal of free parking spaces.
* This is a suggestion, not an assumption required for the argument to be valid.
The correct answer is D. The argument assumes that customers who currently use free parking are likely to visit downtown businesses less often if they have to pay for parking. This assumption is necessary for the businesses' concern about decreased customer traffic to be valid.
While A is also a strong contender, D more directly addresses the link between paying for parking and reduced visits, which is central to the businesses concern
