Its not D because the passage states: "Nor do individuals well understand the personal benefits of natural resources and ecological services"
In the passage it does not define either understanding is short term or long term for the personal benefits.
In option D it is adding information that is not being backed by anything in the passage, hence it is incorrect

A is correct as it states in the passage "[color=#2a2a2a]Moreover, individuals' willingness to pay for natural resources may depend on such factors as whether the expense is borne by all taxpayers or only by those individuals who pay user fees."

Hi,

The passage mentions "But calculating the economic value of ecological goods (natural resources) and services (such as wetland preservation or global climate control) is more difficult, since they may last indefinitely and are generally not traded in markets (no one owns the air or water). " Measuring the economic value of ecological goods and services is difficult does NOT mean they don't possess any value.

Therefore, E is crossed out since it distorts the meaning of the passage.

Question 1



Rishitkg
can someone explain why is option A correct for Q1
The last sentence is the key:

Quote:
Individuals' willingness to pay for natural resources may depend on such factors as whether the expense is borne by all taxpayers or only by those individuals who pay user fees.
A couple of sentences before that, we get this lovely thing:

Quote:
To determine the value of such goods and services, economists ask individuals what they would be willing to pay in a hypothetical market...
So in this context, "individuals' willingness to pay" and "economic value to individuals" are essentially the same.

So the last sentence tells us that the economic value of ecological goods and services (individuals' willingness to pay for natural resources) may be influenced by (or depend on) certain factors: specifically, whether the expense is borne by all taxpayers or only by those individuals who pay user fees. That's just a fancy way of saying: "Who's paying for this stuff?" In other words, "How are the costs of those ecological goods and services distributed?"

So choice (A) is actually very close to what's stated in the passage.

I hope that helps!

Hi, In Q1, Why not E? It is directly mentioned in RC.
Take another look at the language used in (E):

Quote:
E. The main obstacle to calculating the economic value of such goods and services is the indefinite length of time over which they may exist.
You're right that the indefinite length of some goods and services is mentioned as an obstacle to calculating their value, but is there any reason to believe that it's the MAIN obstacle? After all, we get plenty of other obstacles: the goods/services aren't traded in markets; consumers might not understand how they value the goods, and so on.

So that word "main" becomes highly problematic, especially when comparing it to another option that's indisputable. When you're down to two options, these are the kinds of subtleties you want to keep in mind.

Your takeaway: always reread your answers choices and look very closely at those modifiers to help you choose between a correct option and one that's close, but ultimately wrong for a very subtle reason.

I hope that helps!

It is possible that they might become less aware in the future too. The passage does not mention anywhere about the people's awareness increasing or decreasing overtime but only that the possible future changes may complicate the usage of the approach of using willingness to determine value of such types of goods.

According to conventional economic theory, the economic value of a good or service is determined by the extent to which individuals desire the good or service. For goods and services (such as groceries) that are soon "used up," and that are traded in well-functioning markets in which consumers understand the product and its benefits reasonably well, market valuations can readily be calculated. But calculating the economic value of ecological goods (natural resources) and services (such as wetland preservation or global climate control) is more difficult, since they may last indefinitely and are generally not traded in markets (no one owns the air or water). Nor do individuals well understand the personal benefits of natural resources and ecological services. To determine the value of such goods and services, economists ask individuals what they would be willing to pay in a hypothetical market-for example, the maximum fees that they would be willing to pay to use national parks. This approach is problematic not only because of individuals' imperfect understanding of the benefits to themselves but also because of its inability to address possible future changes in people's willingness to pay for ecological goods and services. Moreover, individuals' willingness to pay for natural resources may depend on such factors as whether the expense is borne by all taxpayers or only by those individuals who pay user fees.

The author of the passage would be most likely to agree with which of the following statements about ecological goods and services?

A. Their economic value to individuals may be influenced by how the costs of the good or service are distributed.
B. Their monetary value is usually overestimated by economists utilizing conventional economic theory.
C. Their economic value to individuals can best be determined by ascertaining the maximum fees that people would be willing to pay for such goods and services.
D. People may understand the short-term benefits of such goods and services better than they understand the future benefits of such goods and services.
E. The main obstacle to calculating the economic value of such goods and services is the indefinite length of time over which they may exist.



The passage states that ecological goods and services differ from the goods and services mentioned in the highlighted text in that ecological goods and services

A. have fewer lasting benefits
B. are not usually traded in markets
C. are more likely to be paid for through taxes
D. are less willingly paid for by consumers
E. do not have an economic value that can be calculated



The author of the passage mentions "possible future changes" in the highlighted text most likely in order to

A. caution against the assumption that taxes are the best way to pay for many ecological goods and services
B. cite a factor that could affect economists' calculations of the economic value of ecological goods and services
C. explain why some economists are attempting to develop new methods for calculating the monetary value of ecological goods and services
D. suggest that people are likely to become more aware of the personal benefits of natural resources and ecological services
E. point out that ecological goods and services are likely to become increasingly costly



Hello [b]SergejK MartyMurray @b_sudharsan @sajjad1994[/b]

Can someone please explain answer for Question 3? I opted for Option D here instead.

Thank you!
