Summary
The author concludes that there will be more local cases of flu infection this year than there were last year. Why? Because on top of the flu strains that were present in the area last year, we have a new strain that has infected people this year.
Missing Connection
There’s a difference between the number of cases of flu infection and the number of flu strains. The premises establish that there’s a greater number of flu strains that have infected people this year compared to last year. But this doesn’t tell us that the number of infections is higher, because we might have fewer cases of various individual flu strains.
To prove that the overall number of cases is higher this year, we want to know that, for the strains of flu that were present last year, there hasn’t been a decline in the number of cases of infection. That way, the additional cases from the new strain would guarantee that the overall number of cases this year is higher than last year.

a
Effective approaches have ████ █████████ ██ ████ ████ ███ ███████ ██ ███ ████ ████ ███████ ████ █████
(A) doesn’t establish anything about the number of cases of flu infection. So it doesn’t establish that the number of cases this year is higher than the number last year.
b
It is rare ███ ███ ███████ ██ ███ ██ ███████
(B) doesn’t establish anything about the number of cases of flu infection. So it doesn’t establish that the number of cases this year is higher than the number last year.

(C) doesn’t establish anything about the number of cases of flu infection. So it doesn’t establish that the number of cases this year is higher than the number last year.
d
The new strain ██ ███ ██ ████████ ██ ██ ████ █████████ ████ ███ ███████ ██ ███ ████ ████ ███████ ████ █████
(D) doesn’t establish anything about the number of cases of flu infection. So it doesn’t establish that the number of cases this year is higher than the number last year. The danger presented by a strain does not clearly imply anything about the number of infections for that strain.
e
There will be ██ ███████ ████ ████ ██ ███ ██████ ██ █████ ██ ███ █████████ ███ ██ ███████ ████ ████ ███████ ████ █████
(E) establishes that the number of cases of flu infection this year due to the strains that were present last year will not go down. So if there are additional cases from the new strain, then the overall number of cases this year must be higher than last year.
