Lyme disease is caused by a bacterium transmitted to humans by deer ticks. Generally, deer ticks pick up the bacterium while in the larval stage by feeding on infected white-footed mice. However, certain other species on which the larvae feed do not harbor the bacterium. If the population of these species increased, more of the larvae would be feeding on uninfected hosts, so the number of ticks acquiring the bacterium would likely decline.
Which of the following would it be most important to ascertain in evaluating the argument?
(A) Whether populations of the other species on which deer tick larvae feed are found only in the areas also inhabited by white-footed mice.
(B) Whether the size of the deer tick population is currently limited by the availability of animals for the tick's larval stage to feed on.
(C) Whether the infected deer tick population could be controlled by increasing the number of animals that prey on white-footed mice.
(D) Whether deer ticks that were not infected as larvae can become infected as adults by feeding on deer on which infected deer ticks have fed.
(E) Whether the other species on which deer tick larvae feed harbor any other bacteria that ticks transmit to humans
i somehow picked option D though i realize that ending of D is little dirty (the one i have bolded)
D :Whether deer ticks that were not infected as larvae can become infected as adults by feeding on deer on which infected deer ticks have fed.
my question is can D without that bolded part be contender . my logic is that if adult dear tick do get infected as carriers then no matter what we do to prevent its getting infected in larvae stage we still will find no decline in the humans getting infected
also i am not able to appreciate B as an answer
B: Whether the size of the deer tick population is currently limited by the availability of animals for the tick's larval stage to feed on.
what does animals refers to ? is it referring to the "other species"(the non infected one)
OR
is it referring to "infected" species
i guess its referring to "other species"
but how am i suppose to make such large leaps for something that has not been written ?.in 2 min time i thought D as much a contender as B
instructors plz help
thanks and regards
