I don't understand how this is a strengthen question. Could you please elaborate ? And if so, then how is B not strengthening one decision from John ?
Hi,
In short, John only cares about saving time and money when choosing a journey to work. He has found a new route that would take shorter (saves time), and John also estimates the new route will save on fuel (saves money). John has decided to try out the new route for the next two weeks. We are asked which of the below options would have an effect on this decision:
The daily journey from his home to his office takes John Bond on average an hour and thirty-five minutes by car. A friends has told him of a
different route that is longer in mileage, but will only take an hour and quarter on average, because it contains stretches of roads where it is possible to drive at higher speed.
John Bond's only
consideration apart from the
time factor is
the cost, and
he calculates that his car will consume 10% less gasoline if he takes the suggested new route. --> So the new route is a good option because John's considerations are time and money, and the new route is faster and cheaper. John decides to take the new route for the next two weeks as an experiment.If the above were the only other considerations, which one of the following may have
an effect on the decision John has made?
--> Note that the decision of the question is to "take the new route for the next two weeks as an experiment".(A) Major road work is begun on the shorter (in distance) route, which holds up traffic for an extra ten minutes. The project will take six months, but after it, the improvements will allow the journey to be made in half an hour less than at present.
No, the new road will be available in six months, and John has made a decision about the next two weeks. (B) There is to be a strike at local gas stations and the amount of gasoline drivers may purchase maybe rationed.
I do not think that rationing the gas available to drivers affects the attractiveness of the new route vs the current route. (C) John finds a third route which is slightly longer than his old route, but shorter than the suggested route.
YES. This third route is shorter than the new option he is about to test. It is longer than his current route (but so is the other one). If this third route is as fuel-efficient as the option he is about to test, and if it also has stretches where he can drive faster and save time compared to his current route, then this third route would be a better option than the one he is about to test. This in turn affects his decision of testing the route #2, because he would test route #3 instead. (D) The old route passes the door of a work colleague, who with out a ride, would have to go to work by bus.
We don't know if the colleague pays for part of the trip, so not very relevant... (E) None of the above.
