The mayor boasts that the average ambulance turnaround time, the time from summons to delivery of the patient, has been reduced this year for top-priority emergencies. This is a serious misrepresentation. This “reduction” was produced simply by redefining “top priority.” Such emergencies used to include gunshot wounds and electrocutions, the most time-consuming cases. Now they are limited strictly to heart attacks and strokes.

Which one of the following would strengthen the author’s conclusion that it was the redefinition of “top priority” that produced the reduction in turnaround time?
(A) The number of heart attacks and strokes declined this year.
(B) The mayor redefined the city’s financial priorities this year.
(C) Experts disagree with the mayor’s definition of “top-priority emergency.”
(D) Other cities include gunshot wound cases in their category o top-priority emergencies.
(E) One half of all of last year’s top-priority emergencies were gunshot wounds and electrocution cases.
[Reveal] Spoiler: OA

IMO E

we are looking to strengthen conclusion ...even 5% strengthen would help ...in this case our conclusion is that "the redefinition of the term "top priorty" is the reason of the reduced time" --> to help with this conclusion we are provided with examples of heart attack, electrocution, etc


E) if "gunshot wounds and electrocution cases" were half of the cases. So there is a possibility that because we took these cases out, the overall time gets reduced because these were the cases that took the most time. Thus this somehow supports the conclusion better than others.

Why no A?
If the number of heart attacks and strokes declined this year; and these are actually the top priority cases, that somehow also strengthen the conclusion, does not it?
Thanks.

E

Assume that there were 200 "top priority emergencies" last year. Of that 200, 100 were gunshot wounds and electrocutions. Simply by removing gunshot wounds and electrocutions from the top priority category, would cut the turnaround time in half.

I agree with E for the above explanations.

Noboru, I would say that A in not good because what the argument focuses on is the fact that the mayor redefined the top priorities.
To strenghten the argument we need to continue to focus on this by showing how the fact that the top priorities emergencies no longer include the shotgun wounds and electructions had an impact on the decreased average time.
With A, we only show that the heart attacks and strokes declined, but this doesn't help without knowing about the shotgun wounds and electructions.

Hope this helps...

can you confirm OA?

E seems to be good 2.

But for A, suppose number of wounds had remained unchanged, and number of heart attack was increased. In this case it will strengthen the conclusion.
When they have limited 'Top Priority' to heart attack then why we have to only consider wounds?

How does it matter wounds changed or not? we have redefined our priorities.

E is better choice than A.
Although cases of heart attacks and strokes declined this year, we dont know how much the rate of decline can affect the turnaround time.
As in E, if half of the cases were reported from the scenarios that took maximum time and that are not included in top priority this year, then turnaround time will decrease irrespective of heart attacks and strokes cases reported this year.

(A) is clearly out, since the argument says "time reduction" for the "Top Priority Emergencies" in current year. As compared to the last year time consuming tasks like gunshots/ electro.. excluded in current year. So if these "time consuming tasks" occupy more than 50% of the jobs in last year than this certainly strengthen the conclusion that redefining (removing time consuming jobs) top priority does reduce the time.
E is correct answer!!!!

90 Seconds, probably not too quick for a 700. Cheers!

Re: The mayor boasts that the average ambulance turnaround time, [#permalink] New post 31 Dec 2013, 04:34
CONCLUSION- It is a serious misrepresentation that the average ambulance turnaround time has been reduced this year for top-priority emergencies.
premise- 1. This “reduction” was produced simply by redefining “top priority.”
2. Such emergencies used to include gunshot wounds and electrocutions, the most time-consuming cases. Now they are limited strictly to heart attacks and strokes.

WE ARE LOOKING AT AVERAGE TURNAROUND TIME...we have to prove that by redefining top priority cases the AVERAGE turnaround time reduces.... therefore, by reduction of gunshot and wound cases, average turnaround time for top priority cases has reduced....................

(A) The number of heart attacks and strokes declined this year...... turnaround time will not change.... wrong
(B) The mayor redefined the city’s financial priorities this year.... irrelevant
(C) Experts disagree with the mayor’s definition of “top-priority emergency......experts can continue to disagree..... wrong
(D) Other cities include gunshot wound cases in their category o top-priority emergencies.......why bother about what OTHERS do.....
(E) One half of all of last year’s top-priority emergencies were gunshot wounds and electrocution cases..... yes this will affect the average... which WILL REDUCE.....CORRECT....

Re: The mayor boasts that the average ambulance turnaround time, [#permalink] New post 31 Dec 2013, 08:10
My process:

(A) The number of heart attacks and strokes declined this year. - Do not have any correlations and do not strenghten at all - Incorrect
(B) The mayor redefined the city’s financial priorities this year. - Who cares? - Incorrect
(C) Experts disagree with the mayor’s definition of “top-priority emergency.” - Who cares? - Incorrect
(D) Other cities include gunshot wound cases in their category o top-priority emergencies. - Who cares? - Incorrect
(E) One half of all of last year’s top-priority emergencies were gunshot wounds and electrocution cases. - Correct

Clear E for me but this question seems strange...

For further analysis: One half of all of last year’s top-priority emergencies were gunshot wounds and electrocution cases : If the number of Gunshot would had been only 0.001% than the "redefinition" would had done any effects. But if it is 50%, than it had an effect.

Could we possibly have the OA?
