Lymedisease is caused by a bacterium transmitted to humans by deer ticks.  Generally, deer ticks pick up the bacteriumwhile in the larval stage by feeding on infected white-footed mice.  However, certain other species on which thelarvae feed do not harbor the bacterium. If the population of these other species were increased, more of thelarvae would be feeding on uninfected hosts, so the number of ticks acquiringthe bacterium would likely decline.
Whichof the following would it be most important to ascertain in evaluating theargument?
A.Whether populations of the other species on which deer tick larvae feed arefound only in areas also inhabited by white-footed mice
B.Whether the size of the deer tick population is currently limited by theavailability of animals for the tick's larval stage to feed on
C.Whether the infected deer tick population could be controlled by increasing thenumber of animals that prey on white-footed mice
D.Whether deer ticks that were not infected as larvae can become infected asadults by feeding on deer on which infected deer ticks have fed
E.Whether the other species on which deer tick larvae feed harbor any otherbacteria that ticks transmit to humans
