Milville business spokesperson: Snowmobiles brings many out-of-towners to Milville in winter months, to the great financial benefit of many local residents. So, economics dictate that we put up with the pollution

Environmentalist: I disagree. A great many cross-country skiers are now kept from visiting Milville by the noite an dpollution that snowmibiles generate

Enronmentalist reponds to the business spokesperson by doing which of the following?

a) Challenging an assumption that certain desirable outcome can derive from only one set of circumstances

b) Challenging an assumption that certain desirable outcome is outweighed by negative aspects associated with producing that outcome



I can't understand why the answer is A and not B??

I can't understand either dude! Too many typo's!
Please correct
Thanks

a) Challenging an assumption that certain desirable outcome can derive from only one set of circumstances .Correct First we need to identify the assumption by deducting Evidence & Conclusion of this stimulus.like this-

If Brings out-of-towners Then Financial benefit Happen
If Brings out-of-towners Then Pollution Happen
By deducting we can say that Financial Benefit is some how related to Pollution which the Environmentalist assumed.This is a Necessary assumption Question.

b) Challenging an assumption that certain desirable outcome is outweighed by negative aspects associated with producing that outcome. Outside the Scope of the information provided here

This question requires us to find the assumption made by the Milville business spokesperson.

The spokesperson says:
Premise: Out-of-towners bring pollution, but they also bring financial benefit.
Conclusion: So for financial benefit we must put up with the pollution.

To get to the assumption here just ask the question Why should we put up with pollution, is there no other alternative for financial benefit? and the assumption is: No there is no other alternative.

Answer A correctly states this assumption and the Environmentalist is challenging this assumption by providing alternate means of financial benefit.
