Hi,
lets rephrase the PARA--
There has been no significant show fall in SF. but A rare combination of X and Y will result in significant rainfall.

lets see the choices

A. There has been no snow in San Francisco in 25 years.
Changes the scope. From significant snowfall to No snow

B. There will soon be a snowstorm in San Francisco.
again changes the SCOPE. from snowfall to snowstorm

C. San Francisco is ill-equipped to handle a significant snowfall.
Out of Context-- there is nothing mentioned about preparedness.

D. In some regions, Pacific rain rarely coincides with Canadian cold fronts.
Correct-- this combination, resulting in significant snowfall, has been mentioned as rare conjunction

E. It is not currently snowing in the Bay Area.
Out of context

D

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)

Which of the following do the statements above best support?

A. There has been no snow in San Francisco in 25 years.

We only know that rainfall is not significant since 1976 in SFO. Significant doesn't mean no snow. There this option is not supported by statements above.

B. There will soon be a snowstorm in San Francisco.

Well meteorologists are just predicticing that this conjuction will lead to a snowfall. But predictions may not come true. Not supported.

C. San Francisco is ill-equipped to handle a significant snowfall.

Whether SFO is ill-equipped is not mentioned. Not supported.

D. In some regions, Pacific rain rarely coincides with Canadian cold fronts.

We are given that this is a rare conjunction of a Pacific rainstorm and a powerful front of cold air blowing south from Canada. This option just rephrase this statement. Supported.

E. It is not currently snowing in the Bay Area.

We are given that "that(i.e. no significant snowfall since 1976) could be about to change". But we cannot say from this statement whether it is snowing or not in bay area. Not supported.


Should be D

If the case of rare coincidence is considered then clearly option D satisfies the condition.option A,B,C and partially or completely out of scope
