Re: 770: V47 - Q50: Some experience & strategy [#permalink]
Hi
I'm trying to use your strategy to solve CR questions would you be able to apply the same for the below evaluate type question-
Thanks a lot in advance.

10 . Traverton’s city council wants to minimize the city’s average yearly expenditures on its traffi c signal lights and so
is considering replacing the incandescent bulbs currently in use with arrays of light-emitting diodes (LEDs) as the
incandescent bulbs burn out. Compared to incandescent bulbs, LED arrays consume signifi cantly less energy
and cost no more to purchase. Moreover, the costs associated with the conversion of existing fi xtures so as to
accept LED arrays would be minimal.
Which of the following would it be most useful to know in determining whether switching to LED arrays would be
likely to help minimize Traverton’s yearly maintenance costs?
(A) Whether the expected service life of LED arrays is at least as long as that of the currently used
incandescent bulbs
(B) Whether any cities have switched from incandescent lights in their traffi c signals to lighting elements other
than LED arrays
(C) Whether the company from which Traverton currently buys incandescent bulbs for traffi c signals also sells
LED arrays
(D) Whether Traverton’s city council plans to increase the number of traffi c signal lights in Traverton
(E) Whether the crews that currently replace incandescent bulbs in Traverton’s traffi c signals know how to
convert the existing fi xtures so as to accept LED arrays

Hi chị Van Dang,

Can you help me to understand thoroughly your strategy for CR by applying it to this question? I have tried on your method but failed. Thank chị so much ah!

In an experiment, each volunteer was allowed to choose between an easy task and a hard task and was told that another volunteer would do the other task. Each volunteer could also choose to have a computer assign the two tasks randomly. Most volunteers chose the easy task for themselves and under questioning later said they had acted fairly. But when the scenario was described to another group of volunteers, almost all said choosing the easy task would be unfair. This shows that most people apply weaker moral standards to themselves than to others.

Which of the following is an assumption required by this argument?
A. At least some volunteers who said they had acted fairly in choosing the easy task would have said that it was unfair for someone else to do so.
B. The most moral choice for the volunteers would have been to have the computer assign the two tasks randomly.
C. There were at least some volunteers who were assigned to do the hard task and felt that the assignment was unfair.
D. On average, the volunteers to whom the scenario was described were more accurate in their moral judgments than the other volunteers were.
E. At least some volunteers given the choice between assigning the tasks themselves and having the computer assign them felt that they had made the only fair choice available to them.

Linhtang The last time the OA appeared here was April 2017, so you probably won't get a response. Why not post the question in the CR forum? I am sure someone will be willing to help.

Cheers!
