GMAT PREP CR40

This one seems Evil.

IMO B though not sure

I would go with C)

The argument is more three trailer trucks should be employed.

C) says that most accidents have been between trucks and other vehicles. So by increasing the three trailers trucks there is no guarantee that the accidents will reduce.

IMO B

One more for B !!

between trucks can be any two trucks !!

more experienced drivng the single and double trailer can decrease the accidents !!

vishu

B

argument asserts that trucks are safer. B says its the driver who is safe, not the truck. weakening achieved.

another vote for B

B is the answer as it puts the 'cause' and 'effect' in the right perspective and the other way around to seriously weaken the inference quoted from the argument.

I dont know why you guys think B should be answer.

B is actually in forms is strengthening the argument.

More experienced drivers - better driving

Accidents are caused either by drivers or due to weather conditions. If there is no weather involvement, it means triple trailer trucks would be safer.

The argument says larger trucks i.e. triple trailer trucks cause less number of accidents as compared with single or double ones.

Conclusion: triple trailer trucks should be used to reduce the number of highway deaths.

Lets see other options.

A) - smaller roads restrict large trucks - if roads cannot permit large trucks then companies will be forced to use single or double trailers - ANSWER IMO


B) Check the above reasoning

C) - few collisions are between trucks - out of scope - we are talking about deaths in general

D) - this could be the answer, had it mentioned specific information about single or double trailers

E) - this also strengthens the argument - highest load of the single trailer would still be less than the lowest load of the triple trailer.


OA?

Kindly post the OA with spoiler tags

parallel chase,
suppose you have 100 drivers who drive large trucks and if u have more large trucks, ur small truck drivers will not be able to drive as they are not xprienced.So, more accidents and B weakn the argument. So, IMO B.

may be the drivers of the very large trucks are very experienced which is why they cause less accidents. so if the use of large trucks large increases, road accidents would decrease. this would support the plan and not weaken it

IMO B.

My reasoning is same as Vivek's.

You can't increase the number of the best drivers in a country. If you increase the number of triple trailer trucks then many low quality drivers will shift to triple trailer trucks, and that could increase the number of accidents. Also, the option shows that problem is not trucks but something else.

OA plz? It's a very good question; I would like to see the answer and official explanation also.

there are 2 assumptions in your reasoning

1) the number of small truck drivers are same as large truck drivers

2) small truck drivers wont be given special training to drive the large truck drivers.

Now, there must be some reason why large trucks are driven by the best drivers ~ safe drivers

any thoughts.

care to post the OA poonam?

i agree with PC, changing my answer to A now.
