Sure, it makes sense to wonder what other troubles the businesses might have. Surely parking can't fix everything! However, it's important to note that the argument is about what MUST be done--in other words, what is necessary--rather than what will be sufficient to meet the goal of increasing economic growth. This distinction between sufficient and necessary comes up a fair amount in CR.

Consider a quick example: "You must obtain oxygen in order to live." Can we weaken that assertion by pointing out other things you need, such as food and water? No--oxygen is necessary, even if other things are, too. However, if I said "As long as you can obtain oxygen, you will stay alive," then I'm overlooking other things that you might need, and we can weaken the argument by pointing them out. If the mayor in our argument had said "If we build this ramp, we will save the businesses and have economic growth," then your objection would hold. But since they just said that they NEED the ramp to meet those goals, we don't have to consider other possible problems or needs.

Mayor: The financial livelihood of our downtown businesses is in jeopardy. There are few available parking spaces close to the downtown shopping area, so if we are to spur economic growth in our city, we must build a large parking ramp no more than two blocks from downtown.

The mayor's conclusion is the following:

if we are to spur economic growth in our city, we must build a large parking ramp no more than two blocks from downtown

Notice that the keyword "must" indicates that the mayor's point is that construction of a large parking ramp no more than two blocks from downtown is necessary for spurring economic growth.

The support for the conclusion is the following:

There are few available parking spaces close to the downtown shopping area

We see that the reasoning is basically that since, presumably, parking spaces are necessary for "the financial livelihood of our downtown businesses" and since "there are few available parking spaces close to the downtown shopping area," creating parking spaces through building a large parking ramp no more than two blocks from downtown is necessary for economic growth.

Which of the following, if true, most seriously weakens the mayor's reasoning?

This is Weaken question, and the correct answer will somehow weaken the support provided by the premise or cast doubt on the conclusion.

(A) The city budget is not currently large enough to finance the construction of a new parking ramp.

This choice weakens the case for the wrong conclusion.

The conclusion the correct answer must cast doubt on is that they "must" build a new parking ramp.

This choice casts doubt on the conclusion that they can finance the construction of a new parking ramp.

So, this choice has no effect on the case for the conclusion since information on whether they can finance the construction of a new parking ramp has no effect on the case for the necessity of a new ramp. In other words, a new ramp may be necessary regardless of whether they can construct one.

Eliminate.

(B) There are other more significant reasons for the financial woes of downtown businesses in addition to a lack of nearby parking spaces.

This choice is tricky because it indicates that construction of a parking ramp likely won't be sufficient for the city to achieve economic growth. So, if we aren't clear about exactly what the conclusion of the argument is, we may be tempted to choose this choice.

So, what's wrong with this choice?

The issue with this choice is that the conclusion is not that construction of a parking ramp will be be sufficient for the city to achieve economic growth. The conclusion is that the city must construct a parking ramp to achieve economic growth. In other words, the point is that a parking ramp is necessary for economic growth.

Even if there are other reasons for the financial woes, a parking ramp may be necessary for economic growth. Sure, other things may also be necessary for growth. Still, a parking ramp could be one of the things necessary for growth.

So, the fact that there are other reasons for the financial woes doesn't weaken the case for the conclusion that a parking ramp is necessary.

Takeaway: We need to be careful not to choose a choice just because it mentions an alternative cause of an effect or an alternative reason for a problem. While, in many cases, a choice that brings up an alternative cause weakens an argument, we always have to consider the specifics of the argument and conclusion we're dealing with when choosing an answer.

Eliminate.

(C) Building a parking ramp as much as four blocks from downtown would be sufficient to greatly increase the number of shoppers to downtown businesses.

This choice is interesting.

The reasoning of the argument is that, since there are few parking spaces, they "must" build a large parking ramp "no more than two blocks from downtown."

So, if this choice is true, and "a parking ramp as much as four blocks from downtown would be sufficient to greatly increase the number of shoppers to downtown businesses," we have a reason to doubt the conclusion.

After all, if a parking ramp "four blocks from downtown" would be sufficient to greatly increase the number of shoppers, then a ramp "no more than two blocks from downtown" may not be necessary.

So, this choice indicates that, even though there are few available spaces, it may not be necessary to build a ramp no more than two blocks from downtown.

Thus, this choice weakens the argument.

Keep.

(D) Explosive growth is most often associated with large suburban shopping malls, not small businesses.

We can eliminate this choice by noticing that the conclusion is not that, by constructing a parking ramp, they will achieve "explosive growth." Rather, the point of the argument is that, to achieve any economic growth, they need a parking ramp.

Since they may need a parking ramp regardless of whether constructing one would result in explosive growth, this choice has no effect on strength of the argument.

Eliminate.

(E) Some additional parking spaces could be added to the downtown area without the construction of a parking ramp.

For me, this choice is a little hard to eliminate. After all, if they can add parking spaces without construction of a parking ramp, then maybe they don't need to build one.

At the same time, since (C) clearly means that "a large parking ramp no more than two blocks from downtown" is not necessary, we can confidently choose (C) over this choice.

After all, the fact that "some" spaces could be added without construction of a large parking ramp does not clearly indicate that such a ramp is not necessary. "Some" spaces could be just a few more spaces.

I personally don't really like the fact that this question includes this choice because adding "some" spaces could be enough to solve the problem without "a large parking ramp," but the question is still gettable because what this choice means about the situation is unclear and (C) is such a clearly correct answer.

Eliminate.

Correct answer: C

So I chose B but after reviewing the answers I feel it is option C, my reasons are below:

Option B says that there are other more significant reasons for financial woes. Emphasis on "other" and "more". It means that this option also considers parking as one of the reasons for financial woes albeit one which has less impact. If we go through the question, it doesn't say that parking is the only option to improve financial condition. So, option B doesn't work.

Option C on the other hand has Conditional statement in the conclusion. Sufficient condition: if we are to spur economic growth in our city, Necessary condition: we must build a large parking ramp no more than two blocks from downtown. We can weaken a conditional statement, we can make sure that necessary statement doesn't occur. Option C mentions the parking can be 4 block away, which is in direct contrast to what was claimed in necessary condition.

Hence, option C

Choice B feels like it weakens the argument - if parking isn't the main problem, why focus on it?
But that's not what the conclusion actually claims.

The mayor says we MUST build this specific ramp (large + within 2 blocks) or economic growth won't happen. Even with other problems, this could still be true. The real weakener needs to show we CAN achieve growth WITHOUT these exact conditions.

Passage Analysis

Mayor: The financial livelihood of our downtown businesses is in jeopardy.

The author is a Mayor here, stating that the downtown businesses are in financial danger.

There are few available parking spaces close to the downtown shopping area

Not many parking spaces are available close to the downtown shopping area. As I read this, I understand that this could be a contributing reason why the downtown businesses are not doing financially well.

so if we are to spur economic growth in our city, we must build a large parking ramp no more than two blocks from downtown.

The word so indicates a conclusion, so the author is concluding here on the basis of the previous statement. The conclusion is that to spur economic growth in the city, it is necessary to build a large parking ramp within two blocks from downtown.

It's very important to take a pause here to deeply understand what the conclusion is saying and how it is different from the following version.

V1: so building a large parking ramp no more than two blocks from downtown will spur economic growth in our city

Essentially, the difference between the given conclusion and the new version created is a difference between a necessary condition and a sufficient condition. What do we mean by a necessary condition?

A necessary condition is something that is necessary or required for something to be achieved. So if we say that X is necessary for Y, it means that X is required for Y, or in other words, you cannot have Y without X.

It's important to understand that a necessary condition is just saying something that is necessary or required. It does not say what else might be required. So if X is required for Y, we cannot say that if X happens, Y will happen because there may be other requirements for Y. But we can be sure that if X does not happen, Y will not happen because at least one of the requirements for Y has not been met.

Let's try to understand the meaning of a sufficient condition. A sufficient condition is something that is sufficient or enough for something else to happen. So if X is sufficient for Y, it means that X is enough for Y. In other words, if X happens, it is guaranteed that Y will also happen.

But let's say X does not happen, then what can we say about Y? In this case, we cannot say anything about Y, whether it will happen or not, because X is a guarantee for Y, but it is not saying that it is a requirement for Y. So if X does not happen, we know that one guaranteed way is not happening, but there could be other ways to make Y happen. We are not saying that it is the only way to make Y happen.

This is the difference between a necessary condition and a sufficient condition. The given conclusion is stating a necessary condition, whereas the version I have created is a sufficient condition.

In light of our discussion of necessary and sufficient conditions, we can understand that the given conclusion is essentially saying that building a parking ramp within two blocks of the downtown area is required to spur the economic growth in the city. In essence, the conclusion is saying that if you don't open a parking ramp within two blocks of the downtown area, economic growth will not be spurred. Also, it is important to understand that the conclusion is not saying that opening such parking space is enough to spur the economic growth in the city.

Deconstructing the Question

We are looking for an option that weakens the conclusion.

Options Evaluation

(A) The city budget is not currently large enough to finance the construction of a new parking ramp.

Incorrect. This option says that the construction of a new parking ramp will require more money than the current city budget allows. Basically, this option is presenting a potential hurdle to financing the construction of a new parking ramp.

However, the presence or the absence of hurdles to build the parking ramp does not tell us whether the parking ramp is required to initiate economic growth in the city or not. So, this option has no impact.

(B) There are other more significant reasons for the financial woes of downtown businesses in addition to a lack of nearby parking spaces.

Incorrect. This option says that there are other, more important reasons or causes for the financial problems of downtown businesses—more important than the lack of nearby parking spaces. The option is acknowledging that the lack of nearby parking spaces is indeed a problem, but it is saying that there are more significant problems.

This option would have been a great weakener for the version we created; in other words, if the conclusion were saying that building a parking ramp will initiate economic growth in the city. In that case, this option would severely weaken that conclusion.

However, this option has no impact on the original conclusion because the original conclusion is just presenting one requirement for the economic growth in the city. Even if there are more important requirements or reasons, that does not cast a doubt on whether building a parking space is a requirement or not. For example, if I am saying that having a passport is necessary to travel outside the country, and somebody says that having a visa is much more difficult than having a passport to travel, that does not have an impact on my statement that having a passport is necessary. Having a passport remains necessary, even though there could be other requirements which may be more significant or more difficult to meet.

(C) Building a parking ramp as much as four blocks from downtown would be sufficient to greatly increase the number of shoppers to downtown businesses.

Correct. This option is saying that if you build a parking ramp even four blocks from downtown, that would be sufficient to greatly increase the number of shoppers to downtown businesses. In other words, this option says that building a parking ramp within two blocks is not really necessary. You can have economic growth by building the parking ramp even four blocks away.

So, this weakens the conclusion because it attacks the requirement of the ramp being within two blocks.

It is also important to understand that this option would have had no impact on the version of the conclusion that we created, because in that version, alternate ways to achieve the same outcome would not have an impact.

(D) Explosive growth is most often associated with large suburban shopping malls, not small businesses.

Incorrect. This option has no relevance to the conclusion. The argument is not getting into any distinction between large shopping malls and small businesses.

(E) Some additional parking spaces could be added to the downtown area without the construction of a parking ramp.

Incorrect. Let's consider the following variation of this option:

(E1) A significant number of additional parking spaces could be added to the downtown area without the construction of a parking ramp.

This variation would significantly weaken the conclusion. This is because, in this case, we are saying that we can have a lot of parking spaces without building a new parking ramp. This would indicate that the problem can be solved without building the ramp, which would decrease our belief in the conclusion that building the parking ramp is necessary for economic growth.

However, the original option E has negligible impact on the conclusion because it is saying some parking spaces. Now, some means "at least one." Essentially, this option is saying, "Well, at least one parking space can be added without building a ramp." One or two parking spaces doesn't really have much of an impact. So, this option E is incorrect.

Hi KarishmaB - if the Q stem said which most seriously weakens the plan - would A be the answer?
KarishmaB


Conclusion: To spur economic growth in our city, we must build a large parking ramp no more than two blocks from downtown.

The conclusion says that building a large parking ramp within 2 blocks is necessary to spur economic growth. Note here that we are not looking for a sufficient condition to spur economic growth. We are looking for a necessary condition - there could be other necessary conditions too. It doesn't matter to us. We need to say that building a large parking ramp no more than 2 blocks is not necessary.

A) The city budget is not currently large enough to finance the construction of a new parking ramp.

Irrelevant how it will be achieved. We need to find whether it is necessary or not.

B) There are other more significant reasons for the financial woes of downtown businesses in addition to a lack of nearby parking spaces.

As we discussed before, we are not saying that building parking space is sufficient. We are saying that it is necessary. There could be other things necessary too. So it doesn't weaken our conclusion.

C) Building a parking ramp as much as four blocks from downtown would be sufficient to greatly increase the number of shoppers to downtown businesses.

This tells us that we do not need to build it within 2 blocks. Even 4 blocks will work. So it weakens our conclusion. It clearly says "...to greatly increase the number of shoppers..." so it will spur economic growth.

D) Explosive growth is most often associated with large suburban shopping malls, not small businesses.

Irrelevant. We are not talking about "explosive growth".

E) Some additional parking spaces could be added to the downtown area without the construction of a parking ramp.

What impact "some additional parking" will have, we do not know.

Answer (C)

The question cannot be 'weaken the plan' because there isn't a plan per se. Mayor says that 'to spur economic growth, a parking ramp no more than 2 blocks from downtown is a must.' That is the ARGUMENT of the mayor. There is no 'let's make a ramp' discussion. If there were a plan, then yes the plan is weakened if it is not financially viable.
