### HideShow timer Statistics

In Acadia National Park, there is a large network of gravel carriage roads that are closed to vehicular traffic but open to a variety of other uses. In an attempt to substantially limit the damage that occurs to the carriage roads from overuse during the course of a year, park officials are imposing strict rules during the spring season. From March 15th to May 1st, when the roads are especially soft and more easily damaged, horses and bikes will be prohibited from all carriage roads, and walkers and runners will only be allowed on certain sections.

In assessing whether the park officials' plan to limit the damage to the carriage roads will be successful, it would be most useful to know which of the following?

A. Whether bikes and horses cause more damage to the carriage roads than walkers and runners do.
B. Whether snowmobilers are allowed to use the carriage roads during the winter months.
C. Whether a considerable percentage of carriage road usage occurs from March 15th to May 1st.
D. Whether some sections of the carriage roads are more susceptible to damage from overuse than others.
E. Whether a substantial percentage of visitors to the park ride their bikes on the carriage roads during their visit.

VERITAS PREP OFFICIAL SOLUTION:

This argument assumes that many people are actually using the carriage roads from March 15th to May 1st. What if virtually no one visited the park that time of year? Then this plan would do very little to prevent damage from overuse. Therefore the answer is (C) – if a large percentage of use occurs during this time period then it’s a good plan, and if a small percentage of use occurs during this time period then it’s a bad plan. The relative damage caused by bikes and horses versus runners and runners and walkers is not important (both are being limited and you don’t know the real difference in the limitation). Whether snowmobiles are allowed in winter does not relate to the efficacy of this specific plan – maybe only a few snowmobiles use the roads. (D) is pretty much given already in the stimulus and (E) is also not relevant as you don’t need to know how popular biking is in relation to the total population. Answer is (C).

We are asked to choose the option which is "most helpful" in evaluating the given argument. In this question, A is also helpful in evaluating the given argument but C is the MOST helpful because if the road is most used outside the specified period, then the plan falls apart.

I hope it helps

Why E is wrong?
If substantial percentage of visitors ride bikes then prohibiting them will be useful otherwise not.

I think, E doesn't address question: why the imposition only for spring season, even if 100% of visitors use their bikes?
OTOH, C hits the bulls eye.

Because in spring season, "the roads are especially soft and more easily damaged". So even if small percentage of carriage road usage occurs during March 15th to May 1st then also road will get damaged. So option C does not evaluate the conclusion.

Whereas in option E, if 100% of visitors use their bike and we prohibit them at that time of the year when roads are more susceptible then roads will not get damaged.

IMO, option C fits best if question stem omits soft and more easily damaged part from the argument.

Hi subhamgarg91

What if 100% of visitors use their bike, but nobody uses the carriage roads in the spring season? Does the plan still be useful in protecting the road? NO, even if the roads are soft. When there is NO use at all why worry about softness?

OTOH, if 90% of the usage of the carriage roads happens in the spring season, the plan justifies.. who cares what % of people use bikes (BTW 'horse' is not mentioned in the answer choice E, an indication of trap)

What do u think?

In assessing whether the park officials' plan to limit the damage to the carriage roads will be successful, it would be most useful to know which of the following?

For Evaluation Questions, I think, the best Strategy is the opposite of the one we use in DS. The correct Answer should give us 2 results - Plan Passes and Fails - both at the same time. Look at the solution to understand better.

A. Whether bikes and horses cause more damage to the carriage roads than walkers and runners do.
Yes, bikes and horses cause more damage; therefore, restricting them will limit the damage to the road - Plan Works.
No, bikes and horses do not cause more damage; however, restricting them Will limit the damage to the road. Not as much as restricting walkers and runners would but still, it would help - Plan Works.

Plan works both the times, meaning that this is not a good question to evaluate the plan.

B. Whether snowmobilers are allowed to use the carriage roads during the winter months.
Out of Scope. We don't know whether snowmobiles damage the road or not.

C. Whether a considerable percentage of carriage road usage occurs from March 15th to May 1st.
Yes, considerable percentage of carriage road usage occurs during this time period. Restricting bikes and horses will help - Plan Works.
No, carriage road is not used during this time period. Restricting bikes and horses will not help because people do not use that road in the first place - Plan Fails.

Plan works and fails with 2 different answers to the same question. This is the right option.

D. Whether some sections of the carriage roads are more susceptible to damage from overuse than others.
Out of Scope. More susceptible or Less susceptible, restricting the usage will help.

E. Whether a substantial percentage of visitors to the park ride their bikes on the carriage roads during their visit.

This is a trick option. Plan is to restrict Bikes and Horses while more data is requested only about the usage of Bikes.

Dear Umg,

In my opinion, option C is also not very convincing: the highlighted portion above has an error; it should be "carriage road is not considerably used during this time period", meaning the carriage roads will be used, but lesser (or "will not be used at all", but we cant assume this).

Combining the above information with "From March 15th to May 1st, when the roads are especially soft and more easily damaged" from the passage, we can see that the park officials' plan will limit the damage (or not, but we cant be certain of this).

Haha. I see what you just did here and hope that you see it too. If not, here is the thing..

To find the flaws in argument, it is our own sweet choice about the degree to which we test it. For instance, when I say that - Some Students out of 100 are girls - It is our choice whether we want to assume 1 of them is girl or all 100 of them are girls. This choice is dictated by the kind of argument.

So, in the example above, when you changed the words of my No statement, adding considerably, you changed the degree of "negativity" in the statement and hence the confusion popped up.

The reasons for me picking the extreme negative statement are:

1. "Considerably" is not a quantified word. 3 water glasses may hold a considerable amount of water for a Thirsty Human but for a Thirsty Camel, is would be a very small amount.
2. Argument does not state whether the roads are used at all during that period. So, you are assuming that they are used when you add the word "considerable".

I hope it makes sense.

In Acadia National Park, there is a large network of gravel carriage roads that are closed to vehicular traffic but open to a variety of other uses. In an attempt to substantially limit the damage that occurs to the carriage roads from overuse during the course of a year, park officials are imposing strict rules during the spring season. From March 15th to May 1st, when the roads are especially soft and more easily damaged, horses and bikes will be prohibited from all carriage roads, and walkers and runners will only be allowed on certain sections.

In assessing whether the park officials' plan to limit the damage to the carriage roads will be successful, it would be most useful to know which of the following?

A. Whether bikes and horses cause more damage to the carriage roads than walkers and runners do.

The comparison for damage between bike and horses vs walkers is irrelevant, because both parties do the damage and relative damage is not the theme of the argument.

B. Whether snowmobilers are allowed to use the carriage roads during the winter months.
Snowmobilers are not even in the argument..out of scope.

C. Whether a considerable percentage of carriage road usage occurs from March 15th to May 1st.
Correct choice to see if the plan to conserve the roads will succeed, we need to know if the roads are used substantially during this period.
if it was not so then the plan to conserve will not do very well,while if the roads are heavily used then the plan will work wonders.

D. Whether some sections of the carriage roads are more susceptible to damage from overuse than others.
we already know that some sections are open and some are not, knowing this will not help a lot to the overall plan.

E. Whether a substantial percentage of visitors to the park ride their bikes on the carriage roads during their visit.
this point is out of scope because we are not discussing the choice of transport for the visitors but whether if the impact of the transport modes can be minimized. because both bikes and walking damages the roads.
