If tourists continue to visit Bridges National Park

Question

If tourists continue to visit Bridges National Park at the current rate, the fragile desert environment that the park seeks to protect will be irreparably harmed. The park's Director has put forth a proposal to charge visitors to the park a fee based on the number of hours spent in the park. This fee will induce tourists to limit their time in the park and thus protect the fragile desert environment.

Which of the following is an assumption made in drawing the conclusion above?

Which of the following is an assumption made in drawing the conclusion above?

B. Most tourists will easily be able to pay the fee even if they do not reduce the number of hours that they spend in the park.
C. The fee will not induce tourists to enter the park early in the morning before the fee collection station has opened and leave only after the fee collection stations has closed for the night. 
D. Protecting the fragile desert environment is an important issue for most visitors to the park.
E. Tourists who do not wish to pay the fee can visit the nearby Chasmland National Park.

A. Tourists will limit the amount of time they spend in the park by hiking only the shorter trails in the park.  Possible answer. But it does not take into consideration that the tourists might increase the time by resting or detailed sightseeing on these short trails.

B. Most tourists will easily be able to pay the fee even if they do not reduce the number of hours that they spend in the park.  Assumption out of scope.

C. The fee will not induce tourists to enter the park early in the morning before the fee collection station has opened and leave only after the fee collection stations has closed for the night.  Highly probable since the tourists can avoid paying the fee if they do so, thereby defeating the purpose of the new arrangement.

D. Protecting the fragile desert environment is an important issue for most visitors to the park.  Assumption is beyond scope.

E. Tourists who do not wish to pay the fee can visit the nearby Chasmland National Park.  Out of scope.

C
As it is the only loophole to the new entry fee policy, and the management would have to assume that that won't happen to believe in the efficacy of their new policy.

Srija221 · Answer

I did not understood how C is the correct answer choice?

Since the argument has stated that tourists will limit the number of hours they spend in the parks if a fee is introduced.So tourists are not likely to pay a high fee if they want to spend greater number of hours in the park or fee is an important factor for the tourists to determine wether they want to spend more hours.Whereas option C introduces additional premise.
Can anyone please explain it?

Hey, so yeah, the tourists should ideally limit their costs because they wouldn't want to pay more.

But what if people started entering the park before the toll booth opens, and start staying back until the toll booth is closed. If that were a possibility more people would start doing that to avoid paying the fee, and that would defeat the purpose of limiting hours spent by people.

So, if the plan were to be a success, the park authorities/management would have to assume that people won't do this.

C is the only option that presents a situation that the management would have had to assume would not arise for their plan to work.

Look at the other options.

A> Good, we want people to limit their time.  An effect, not an assumption. 
B> Weakening Statement
D>Maybe, the reason why people are fine with the new policy, but not an assumption
E> New park? Out of scope.

Hope this helps. 
 Kudos me please!

ArupRS · Answer

Srija221  Opton Aa actually weakens the conclusion by stating one possible reason which may fail the proposal. Whereas, in option C, provides a piece of information which binds the argument. 
An assumption is indeed an additional unstated premise.

Hi..

The park's Director plans to charge the number of hours of stay. So, A can even be an assumption that tourists will have shorter trails to avoid being charged more.

How can the OA be C??

Mona2019 · Answer

A states : Tourists will limit the amount of time they spend in the park by hiking only the shorter trails in the park.
the statement means how the tourists will be spending the limited time in the park.
It does not concern . as long as the timing is followed.

Yesul · Answer

The conclusion is  "The fee is effective in reducing tourists' time in the park and thereby protect the environment"

Choice A:The reason why the answer is not A is because it does not really have to be true for the conclusion to be true. 
Whether they pay the fee or not, they can reduce the time or they don't need to. The answer choice doesn't explain the effectiveness of the fee on reducing tourists' time.

Choice C: If you negate the answer choice C, then the making people to pay the fee becomes ineffective.

napolean92728 · Answer

The  correct answer is (C)  The fee will not induce tourists to enter the park early in the morning before the fee collection station has opened and leave only after the fee collection stations has closed for the night.
Let's analyze the argument:
 
 Premise: Tourists at current visitation rates will harm the desert environment 
 Proposed solution: Charging a fee based on hours spent in the park 
 Conclusion: This fee will induce tourists to limit their time, thus protecting the environment

For this conclusion to be valid, we need to assume that tourists won't find ways to circumvent the fee while still spending the same amount of time in the park. Option C identifies a critical assumption - that tourists won't game the system by entering before and leaving after fee collection hours, which would undermine the entire purpose of the hourly fee.

Why are the other options incorrect: 
 (A)  The argument doesn't require assumptions about which trails tourists will choose. The conclusion only depends on tourists reducing their overall time in the park, not how they spend that time.
 (B)  This weakens the argument. If tourists can easily afford the fee without reducing their time, the fee won't achieve its purpose of protecting the environment.
 (D)  Whether tourists care about protecting the environment is irrelevant. The fee is meant to change behavior regardless of tourists' environmental values - it's an economic incentive, not an appeal to values.
 (E)  The availability of alternative parks isn't necessary for the hourly fee to be effective in reducing time spent at Bridges National Park. The argument is specifically about how the fee will affect behavior at this particular park.
