Scientists recently documented that influenza spreads around the world

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.

Answer: B) requiring air travelers to receive flu vaccinations far enough in advance of the trip to provide protection against the disease.

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

Is it B?

I believe so because actions taken before the air travel would prevent such infections during the air travel

Option B

Minimise spread of flu - flue spreads if --> persons develop symptoms on the flight, or is still nascent and travels before symptoms - we don't have to worry after developing coz they won't travel

(A) installing air filtration systems in the planes to kill any flu virus particles flowing through the filters - maybe, but still till it reaches vents itis spreading
(B) requiring air travelers to receive flu vaccinations far enough in advance of the trip to provide protection against the disease - Yes
(C) refusing to allow children, the elderly, or others who are especially vulnerable to flu to travel by air during a pandemic - uhmm but it can still spread to other countries from the infected passager
(D) requiring all air travelers to wash their hands before boarding a plane uhmm no
(E) conducting medical examinations during the boarding process to weed out passengers with flu symptoms - but passage talks about people without symptoms

Manhattan Prep Official Solution:

(B).

You are presented with a paragraph of premises and asked to resolve the problem they present: how to minimize the spread of flu via air travel. The correct answer will need to rely specifically on the premises and will not require you to make any inferences or assumptions.

(A) The passage states that the infection can be spread by coughing. The flu virus, therefore, can reach the other passengers in the “closely-packed environment” before it enters any filters that might kill the virus.
 
(B) CORRECT . Vaccines provide significant protection against developing the virus (not 100% protection, but you are asked to “minimize” the impact of air travel, not eliminate it entirely). If all passengers are vaccinated against the virus, many of those who otherwise would have developed the disease will not, and, therefore, won’t spread it to others.

(C) Anyone can contract the virus and subsequently spread it; the mentioned populations are merely “especially vulnerable” to it. Infected people traveling to another place can infect children, senior citizens, and others who have stayed in their home regions.

(D) The passage states that the infection can be spread by coughing; while it may be true that the virus can also spread via hand contact, this information is not stated in the passage.

(E) The passage states that people who develop symptoms before travel begins likely would not make the trip; weeding out those with observable symptoms, then, won’t “minimize” the role of air travel because there aren’t that many people in this category. The larger danger is those who may be infected but have not yet developed symptoms.
