Please help! The graph shows the effect of the number of passengers on the number of crashes per 10,000 trips.

A graph titled Crashes by Number of Passengers and Driver Age shows number of passengers with drivers ages 16 to 17 on the horizontal axis and crashes per 10,000 trips on the vertical axis. 0.5 crashes had 0 passengers. 2.5 crashes had 1 passenger. 3.5 crashes had 2 passengers. 6.5 crashes had 3 or more passengers.

About how many times more likely is a 17-year-old driver to crash with three passengers than with one passenger?

about twice as likely
about three times as likely
about four times as likely
about five times as likely

Which of the following best reflects what we know about how the flu virus moves between species? a) the flu virus in a pig is mutated and replicated in alternate arrangements so that humans who eat the pig products can be infected.b) a flu virus from a human epidemic or pandemic infects birds; the birds replicate the virus differently and then pass it back to humans.c) an influenza virus gains new sequences of dna from another virus, such as a herpesvirus; this enables it to be transmitted to a human host.d) an animal such as a pig is infected with more than one virus, genetic recombination occurs, the new virus mutates, the virus is passed to a new species such as a bird, and the virus mutates again and can now be transmitted to humans.
