prep test 32 section 1 #18Until 1985 all commercial airlines completely replenished the cabin air in planes in flight once every 30 minutes. Since then the rate has been once every hour. The less frequently cabin air is replenished in a plane in flight, the higher the level of carbon dioxide in that plane and the easier it is for airborne illnesses to be spread.Q: which one of the follwing is most strongly supported by the information above?b) People who fly today are more likely to contract airborne illnesses than were people who flew prior to 1985..e) in 1980 the level of carbon dioxide in the cabin air on a two-hour commercial airline flightwas lower than it is today on a similar flight..(answer)Why not B is the answer?I think B is right inference..
the questions deals with level of CO2, not airborne illness. you cannot draw any conclusions about airborne illness and contracting one given the information. you can only draw conclusions about the level of CO2 before and after 1985.
