Scientists Recently Documented That Influenza Spreads Around The World GMAT Critical Reasoning

Question: 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

Answer: B
Explanation

(A) installing air filtration systems in the planes to kill any flu virus particles flowing through the filters. The given statement is incorrect because it is said that the infection can be spread by coughing and the flu virus can be transferred to any passenger in the closely packed environment before it reaches the air filtration system.

(B) requiring air travelers to receive flu vaccinations far enough in advance of the trip to provide protection against the disease. The given statement is correct because if the passengers will get the vaccination before traveling then they can save themselves from the infected persons traveling along with them.

(C) refusing to allow children, the elderly, or others who are especially vulnerable to flu to travel by air during a pandemic. The given statement is incorrect because the passage didn't explain which age group will be more vulnerable to the flu virus.

(D) requiring all air travelers to wash their hands before boarding a plane. The given statement is incorrect because it is clearly stated that the virus can spread through the cough but it is not stated that it can also transfer through hand-to-hand contact.

(E) conducting medical examinations during the boarding process to weed out passengers with flu symptoms. The given statement is incorrect because the given solution cannot be valid in every situation as there are some passengers who are infected but they have not developed any symptoms yet. So, they will not be able to weed out such passengers.
