Citizen: Our legislators need to act quickly to counter the effects of the recession, especially the present level of unemployment, which is the highest ever. We urgently need a major tax cut for our upper-income citizens. There would then be a correspondingly large increase in investment that would create new jobs. If this measure is not taken, investment will not grow.We see that the citizen has reasoned that, since there is a recession involving "the highest ever" level of unemployment, a major tax cut for upper-income citizens is needed. The citizen goes on to say that such a tax cut would result in a large increase in investment.
This passage doesn't work the way GMAT Critical Reasoning passages tend to work since there's no defined main conclusion with a clear supporting premise. Rather, the passage presents a set of related statements about a tax cut and an increase in investment.
The citizen's argument depends on the assumption thatThis question is an Assumption question, and the correct answer will state something that must be true for the argument to work.
Since the passage isn't quite like most GMAT CR passages, answering the question won't work quite the same as answering a GMAT Assumption question generally does. All the same, we can still find an assumption that's necessary for the argument to hold together.
(A) the recession in the citizen's country is the worst one in its historyThe argument doesn't depend on this choice. After all, even if the recession is not the worst one in the country's history, it still appears to be a major recession given the high rate of unemployment. So, it could still make sense that a tax cut that would stimulate investment is urgently needed.
Eliminate.
(B) the greater the tax cut given to a group of people, the more likely it is that members of that group will invest the moneyThis choice is tricky because it does appear that the citizen is assuming that a tax cut makes it more likely that upper-income citizens will invest money. So, this choice could appear to be state something upon which the argument depends.
At the same time, if we look at this choice carefully, we see that it's not quite what the argument needs.
For one thing, the argument is not about just any "group of people." It's about upper-income citizens specifically. So, the argument doesn't require an assumption about an nonspecific "group of people." The argument requires only information about "upper-income citizens."
Another issue is that the argument is about a binary choice: a major tax cut versus no tax cut. It's not about how making tax cuts bigger will make people more likely to invest. So, the argument doesn't require there to be some kind of correlation between the size of a tax cut and the likelihood that people will invest.
In other words, even if a tax cut that is "greater" than "major" won't make it even more likely that people will invest, the argument works.
So, the argument doesn't require it to be the case that "the greater the tax cut given to a group of people, the more likely it is that members of that group will invest the money."
Eliminate.
(C) upper-income citizens have invested more money in total than have lower-income citizensNotice that this choice is about what people "have invested"
in the past.
In contrast, the argument is about the
future effects of a tax cut. So, it doesn't require this statement about what people have done in the past to be true.
After all, regardles of whether, in the past, upper-income ciitzens have invested more than lower-income citizens, it could still be the case that a major tax cut would cause upper income citizens to invest.
Eliminate.
(D) upper-income citizens would use the money gained from the tax cut in ways that increase investmentThis choice is interesting.
After all, the citizen says, "Our legislators need to act quickly .... We urgently need a major tax cut for our upper-income citizens. There would then be a correspondingly large increase in investment that would create new jobs."
In saying that, the citizen is assuming that "upper-income citizens would use the money gained from the tax cut in ways that increase investment."
After all, if they would not use the money in ways that increase investment, then it doesn't make sense to conclude that, if there's a tax cut, "There would then be a correspondingly large increase in investment that would create new jobs."
Of course, in that case, it also doesn't make sense to say that a tax cut for upper-income citizens is urgently needed.
In other words, if this choice is not true, the citizen's argument falls apart.
So, this choice states an assumption on which the argument depends.
Keep.
(E) in the past, tax cuts for certain groups of people have tended to create new jobsNotice that, like (C), this choice is about the past, whereas the argument is about the future effects of a tax cut. So, the argument does not depend on this choice.
After all, even if there have never been tax cuts in the past or tax cuts have not resulted in job creation in the past, it could still be that, in this particular case, a tax cut for upper-income citizens would result in job creation.
Eliminate.
