Citizens of Parktown are worried by the increased frequency of serious crimes committed by local teenagers. In response, the city government has instituted a series of measures designed to keep teenagers at home in the late evening. Even if the measures succeed in keeping teenagers at home, however, they are unlikely to affect the problem that concerns citizens, since most crimes committed by local teenagers take place between 3pm and 6pm.

Which of the following, if true, most substantially weakens the argument ?

(A) Similar measures adopted in other place have failed to reduce the number of teenagers in the late evening

(B) Crimes committed by teenagers in afternoon are mostly small thefts and inconsequential vandalism

(C) Teenagers are much less likely to commit serious crimes when they are at home than when they are not at home

(D) Any decrease in the need for police patrols in late evening would not mean that there could be more intensive patrolling in the afternoon

(E) The schools in Parktown have introduced a number of after school programs that will be available to teenagers until 6pm on weekday afternoons

P1: people worried by increased serous crimes committed by teenagers.
P2:Teenagers were forced to stay in home in late evenings
C:they could not control because most crimes are committed between 3-6.

in oder to weaken the conclusion we need to show a small flaw in the conclusion drawn.

remember the word serious crimes is used in the P.that word plays the crucial role here.

If we succeed to show that serious crimes are committed @nights or minor crimes are committed between 3-6 we win.

Which of the following,if true, most substantially weakens the argument ?

1) Similar measures adopted in other place have failed to reduce the no of teenagers in the late evening
This info is of no importance.

2) Crimes committed by teenagers in afternoon are mostly small thefts and inconsequential vandalism Bingo!!

3) teenagers are much less likely to commit serious crimes when they are at home than when they are not at home
this needs few more assumptions to be true.

4) Any decrease in the need for police patrols in late evening would not mean that there could be more intensive patrolling in the afternoon out of scope

5) The schools in parktown have introduced a number of after school programs that will be available to teenagers until 6pm on weekday afternoons
So What? on Weekends wat will happen

The arguement here describes a plan by city government to stop "serious" crimes teenagers commit and thereafter, the argument criticizes the plan as "most" crimes commited by teenagers are in afternoon.
Please emphasize on the word "serious" used in favour & "most" used to oppose. If any option proves that "most" crimes committed are not serious, then the government plan will still hold true as its main purpose is to decrease "serious" crimes.

Hence option B is the best choice among others.

Conclusion: they are unlikely to affect the problem that concerns citizens, since most crimes committed by local teenagers take place between 3 p.m. and 6 p.m.

Reasoning: The incorrect answers are ones that strengthen the answer choices or others that are neutral. Weakening the conclusion must attack the conclusion so as to prove that it's not likely crimes are committed between 3 pm to 6 pm (with the series of measures instituted)

A. Similar measure adopted in other places have failed to reduce the number of teenagers on the streets in the late evening Wrong - opposite answer; we need why the measures work. It's certainly a trap answer.

B. The crimes committed by teenagers in the afternoon are mostly small thefts and inconsequential vandalism. Correct - "serious" modifies the crimes, whereas the "small" and "inconsequential" modify most of the crimes that occur from 3pm to 6pm.

C. Teenagers are much less likely to commit serious crimes when they are at home than when they are not at home. Wrong - Neutral. Indeed teenagers can't commit serious crimes when they are at home.

D. Any decrease in the need for police patrols in the late evening would not mean that there could be more intensive patrolling in the afternoon. Wrong - opposite answer. This is opposite because the answer must weaken the conclusion that the measures are likely to succeed.

E. The schools in Parktown have introduced a number of after-school programs that will be available to teenagers until 6 p.m. on weekday afternoons. [color=#ed1c24]Wrong - this does not properly weaken the conclusion because we don't know if the teenagers will attend /color]

IMO B

+1 for B

Conclusion of the argument : they(the steps) are unlikely to affect the problem that concerns citizens.

The Key player in the conclusion is "the problem", which is defined in the first sentence of the argument => Citizens of parktown are worried by the increased frequency of serious crimes committed by local teenagers

B weakens the argument by suggesting that crimes that would be committed by teenagers would not be serious crimes.

PREMISE: Increased frequency of SERIOUS crimes committed by local teenagers.
PREMISE: City introduced "curfews" to keep teenagers at home at night.
PREMISE: Most crimes committed by local teens occur between 3pm and 6pm.
CONCLUSION: Curfew unlikely to reduce SERIOUS crimes committed by local teens.
Aside: I added SERIOUS, because we're told that citizens are worried about the increase in SERIOUS crimes.

(A) Similar measures adopted in other place have failed to reduce the number of teenagers in the late evening
Does this weaken the conclusion that the curfew is unlikely to reduce SERIOUS crimes committed by local teens.?
No. This premise actually STRENGTHENS the author's conclusion by suggesting that the curfew will be largely ignored.
ELIMINATE A

(B) Crimes committed by teenagers in afternoon are mostly small thefts and inconsequential vandalism
Does this weaken the conclusion that the curfew is unlikely to reduce SERIOUS crimes committed by local teens.?
YES!
If most afternoon teen crimes are NOT serious, then it's quite possible the SERIOUS crimes committed by teens occur at night, in which case the curfew just may help to reduce SERIOUS crimes.
KEEP B

(C) Teenagers are much less likely to commit serious crimes when they are at home than when they are not at home
Does this weaken the conclusion that the curfew is unlikely to reduce SERIOUS crimes committed by local teens.?
NO.
As it stands (when we ignore answer choice B), it SOUNDS like most crimes (serious and non-serious) occur from 3 - 6pm. So, any kind of late-night curfew will have no effect on crime.
ELIMINATE C.

(D) Any decrease in the need for police patrols in late evening would not mean that there could be more intensive patrolling in the afternoon
Does this weaken the conclusion that the curfew is unlikely to reduce SERIOUS crimes committed by local teens.?
NO. The conclusion is all about whether the teen CURFEW will reduce crime.
ELIMINATE D.

(E) The schools in Parktown have introduced a number of after school programs that will be available to teenagers until 6pm on weekday afternoons
Does this weaken the conclusion that the curfew is unlikely to reduce SERIOUS crimes committed by local teens.?
NO. The conclusion is all about whether the teen CURFEW will reduce crime.
ELIMINATE E

Cheers,
Brent

I think it is B because it cites the instances of small/petty thefts whereas the Paragraph quotes facts of Serious crimes.

Hi All

The answer is "B"..Reason as follows in the trail...

Quote:
Citizens of parktown are worried by the increased frequency of serious crimes committed by local teenagers. In response, the city government has instituted a series of measures designed to keep teenagers at home in the late evening. Even if the measures succeed in keeping teenagers at home, however, they are unlikely to affect the problem that concerns citizens, since most crimes committed by local teenagers take place between 3pm and 6pm

a)Similar measures adopted in other place have failed to reduce the no of teenagers in the late evening...Insufficient ,what kind of measures not elaborated between 3 pm and 6pm?..Incorrect

b)Crimes committed by teenagers in afternoon are mostly small thefts and inconsequential ...At least the Best argument making sense during the time frame 3pm to 6 pm

c)teenagers are much less likely to commit serious crimes when they are at home than when they are not at home..No relevance ...substatiate data unavailable to proove this.

d)Any decrease in the need for police patrols in late evening would not mean that there could be more intensive patrolling in the afternoon ..Police patrolling or roles is not the subject of the statement and is completely irrelevant.

e)The schools in parktown have introduced a number of after school programs that will be available to teenagers until 6pm on weekday afternoons...Specific mention of "weekdays" makes it a no go...had the term "weekdays" not been included this would have been the undisputed and best option among the 5...

I think the major problem for me here is that I do not understand what the actual argument is. It seems to me the final argument states that the government effort to reduce serious teenage crime will proof ineffective due to the fact that the majority of the crimes are commited during 3pm and 6pm, but it does NOT state the nature of these crimes (serious or not).

Now if I look at the correct answer, which states that crimes comitted during the evening are NOT SERIOUS crimes, Does that not mean that the government effort will proof ineffective, since serious crimes are NOT observed in the evening, and isn't the argument with which the passage ends strengthened by this statement????

PLEASE SOMEONE TELL ME WHAT I AM DOING WRONG

Here's how I would answer this weaken the argument question:
First, Summarize the main point - Increase in serious crimes by teens therefore current plan is to keep teens indoors at night.
Second, State the assumption -Most Serious crimes happen between 3pm and 6pm only/daytime
Goal - Destroy the assumption

Option A: Out of scope - similar measures adopted in other places is irrelevant to this argument
Option B: Correct - The crimes committed by teenagers in the afternoon are mostly small thefts and inconsequential vandalism - This destroys the assumption that most serious crimes are committed between 3pm and 6pm or daytime only.
Option C: Out of scope - Redundant information and also no mention of the actual time of day
Option D: Completely Out of scope
Option E: Warp answer - Kind of addresses a part of the argument but not fully because it only takes the weekdays into account

Hope this makes sense

Clearly B.
Since the parents are worries about the violent crimes commited by teenagers. There is no mention whether they have any issue with non violent crimes.
Problem with E : The afternoon programs ara available to students on weekdays.
1) will students avail such programs. These programs are not mandatory.
2) Programs are only available to students on weekdays : how about weekends?

E looks good.

The question says substantially weaken. E would weaken his claim a little bit. But we don't know how many kids will go to these things. B) Destroys it. If all the crimes committed in the afternoon are petty then clearly his argument that this plan won't do anything is destroyed. Since this plan may take kids off the streets later when they do serious crimes.

The problem with B is it says substantially weaken his argument. First of all the new plan by the schools is different from the city plan. So it's already out of the scope. E says very little about the new proposal and its effectiveness. B directly talks about it. If B is true then the plan may work

A. Similar measure adopted in other places have failed to reduce the number of teenagers on the streets in the late evening

This strengthens his argument that it won't work

B. The crimes committed by teenagers in the afternoon are mostly small thefts and inconsequential vandalism.

This one looks good for now. His conclusion is that most crimes happen between 3PM and 6PM and therefore unlikely to help concerned citizens. However, this sells all the crimes are small so this is a good answer.

C. Teenagers are much less likely to commit serious crimes when they are at home than when they are not at home.

This conclusion if true is fine but it doesn't weaken the authors argument that most crimes happen between 3-6PM. So he says fine it will work from 7-10PM but it won't work from 3-6 when they are not at home. So it is out of the scope. It restates what we know.

D. Any decrease in the need for police patrols in the late evening would not mean that there could be more intensive patrolling in the afternoon.

Notice the weird use of not after "would." Also GMAT doesn't like weak language like "there could be." Clearly this could doesn't substantially weaken his argument. It does weaken but not substantially cuz of weak language. Also the weird negative may mean not at all.

E. The schools in Parktown have introduced a number of after-school programs that will be available to teenagers until 6 p.m. on weekday afternoons.

This is probably the second best answer. GMAT doesn't like you to assume to much. So we have no data if the students will attend or anything. So this weakens a little bit. Also, one would think the students committing the crimes wouldn't attend these programs anyways.

so the answer is B, E is the second closest

(A) Similar measures adopted in other place have failed to reduce the number of teenagers in the late evening -- out of scope
(B) Crimes committed by teenagers in afternoon are mostly small thefts and inconsequential vandalism --- good contestent for weaken
(C) Teenagers are much less likely to commit serious crimes when they are at home than when they are not at home -- strengthen the argument
(D) Any decrease in the need for police patrols in late evening would not mean that there could be more intensive patrolling in the afternoon --out of scope
(E) The schools in Parktown have introduced a number of after school programs that will be available to teenagers until 6pm on weekday afternoons --- it doesnt talk about weekend.

I think only B is weakening the argument since that time no serious crime is being committed, hence measure will be effective.

A. Similar measure adopted in other places have failed to reduce the number of teenagers on the streets in the late evening

This rather strengthens her argument that the new measure will not reduce the crime.

B. The crimes committed by teenagers in the afternoon are mostly small thefts and inconsequential vandalism.

This choice seems good to me. According to the argument, the town is worried about the "serious" crimes committed by teenagers in the evening. The choice (B) states that the crimes committed by teenagers are "small and inconsequential." Therefore, the "serious" crimes committed by teenagers are in the late evening. This situation is favorable for the new measure to prohibit teenagers from going out in the late evening.

C. Teenagers are much less likely to commit serious crimes when they are at home than when they are not at home.

This choice does not weaken her argument. She claims that the new measures will not reduce the crime because the most crimes are committed from 3 p.m. and 6 p.m. while the teenagers will be kept at home by the new measures only after 6 p.m.

D. Any decrease in the need for police patrols in the late evening would not mean that there could be more intensive patrolling in the afternoon.

The measure may work well if the police had more intensive patrolling (from 3 p.m. to 6 p.m.) because of the decrease in the need for police patrols (in the late evening). The choice (D), however, states otherwise.

E. The schools in Parktown have introduced a number of after-school programs that will be available to teenagers until 6 p.m. on weekday afternoons.

Teenagers who might commit serious crimes may not join the activities. Even if they do, it works only on weekdays.

Conclusion: The police program will not affect the increased frequency of serious crimes committed by local teenagers

Premise: most crimes take place between 3pm and 6pm
Prem2: The plan is to keep teenagers at home in the late evening

Weaken the conclusion

A - what is true of other places may not be true of this place. Incorrect.
B -
Afternoon = 12pm till sunset (typically 6pm)
Evening =part of the day between end of afternoon and night
Late evening = into the night

B is correct as it says that since most crimes occur between 3pm and 6pm are not serious, the serious crimes could either be committed in the morning or the evening, so potentially the plan will have its desired affect.

B is correct.

C is incorrect as it says that since most serious crimes are comitted outdoors the citizens still have cause for concern that serious crimes will increase since most of the crimes are comitted in the late afternoon.
We would need to spin more of a story than B to determine when exactly the serious crimes would be committed.

D is incorrect - it appears to strengthen the argument as D says that police patrol resources won't be re-routed to reduce crimes taking place between 3 and 6pm, so there is still cause for concern that serious crimes occur here.

E is incorrect - we don't know whether teenagers will take up these programs to start. Second, if the schools have already introduced the program --as indicated-- but the crimes are still taking place, then this program is obviously failing
