There has been no significant snowfall in San Francisco since 1976, but that could be about to change: meteorologists are predicting that the rare conjunction of a Pacific rainstorm and a powerful front of cold air blowing south from Canada will lead to the region’s first significant snowfall in over 25 years.
Which of the following do the statements above best support?
A. There has been no snow in San Francisco in 25 years.
B. There will soon be a snowstorm in San Francisco.
C. San Francisco is ill-equipped to handle a significant snowfall.
D. In some regions, Pacific rain rarely coincides with Canadian cold fronts.
E. It is not currently snowing in the Bay Area.
Hi
VeritasKarishma,
I was stuck between answer choice D and E. Although answer choice 'E' seemed clearly wrong after a little more investigation, I selected D. But answer choice 'D' says -
In some regions, Pacific rain rarely coincides with Canadian cold fronts. -
In this scenario can we still assume that "In some regions" are still referring to some regions in San Fransisco. I felt this is a little ambiguous.
No significant snowfall in SF in 25 yrs
The rare conjunction of a Pacific rainstorm and a powerful front of cold air from Canada will lead to the region’s first significant snowfall in over 25 years.
So SF will see significant snow.
We are looking for an inference. Something that must be true according to argument above. Hence, the correct option should bring in no new information.
A. There has been no snow in San Francisco in 25 years.
The argument talks about "significant" snow.
B. There will soon be a snowstorm in San Francisco.
We don't know whether there will be a "snowstorm". We only know there will be "significant" snow.
C. San Francisco is ill-equipped to handle a significant snowfall.
Out of scope. No idea.
D. In some regions, Pacific rain rarely coincides with Canadian cold fronts.
Correct. We definitely know that in SF Pacific rain rarely coincides with Canadian cold fronts. So we can say that in "some regions" this happens. We already have one example where it happens. "Some" means "at least one".
Option (D) is true as per our argument.
E. It is not currently snowing in the Bay Area.
We don't know. The argument talks about "significant" snow. It could be currently snowing in SF but a little bit only.
Answer (D)
