Scientists recently documented that influenza spreads around the world more efficiently in the modern era due to commercial air travel. Symptoms of a pandemic-level flu are severe enough that the ill would likely cancel or reschedule air travel, but an infected person can travel across the globe before the first signs appear. Further, if symptoms develop while someone is still on a plane, the infected person's cough can spread the virus easily in the enclosed and closely packed environment.

Which of the following would best minimize the role air travel can play in the spread of influenza during a pandemic?
(A) installing air filtration systems in the planes to kill any flu virus particles flowing through the filters
(B) requiring air travelers to receive flu vaccinations far enough in advance of the trip to provide protection against the disease
(C) refusing to allow children, the elderly, or others who are especially vulnerable to flu to travel by air during a pandemic
(D) requiring all air travelers to wash their hands before boarding a plane
(E) conducting medical examinations during the boarding process to weed out passengers with flu symptoms

Went with B, for the following reason.

A) installing air filtration systems in the planes to kill any flu virus particles flowing through the filters. But happens if the infected person is already in the plane and starts coughing ?
(B) requiring air travelers to receive flu vaccinations far enough in advance of the trip to provide protection against the disease. This will ensure safety.
(C) refusing to allow children, the elderly, or others who are especially vulnerable to flu to travel by air during a pandemic. No mention of kids or elders
(D) requiring all air travelers to wash their hands before boarding a plane. We don't know that, not mentioned.
(E) conducting medical examinations during the boarding process to weed out passengers with flu symptoms. We know the symptoms takes long to appear.
