Although many people would not believe it,
the mosquito is actually the most dangerous
animal in Africa. While the bite of the black
mamba is invariably lethal when untreated,
this dreaded snake kills only a few dozen
people per year. Hippopotami, with their
immense strength and foul dispositions, kill
hundreds of people per year in rivers and
lakes, but the mosquito is still more
dangerous. Mosquitoes bite hundreds of
millions of people in Africa every year, and
they infect over a million each year with
malaria, a disease that is often fatal.
Which of the following questions would be
most useful in evaluating the claim made
above regarding the mosquito?

A. Could a person survive an attack by a
black mamba if that person received
prompt medical attention?
B. What criteria are used to determine which
animal is the "most dangerous" animal?
C. Could the incidence of mosquito bites be
decreased through the judicious use of
pesticides and insect repellent?
D. Does malaria kill more people per year in
Africa than tuberculosis?
E. How does the percentage of people who
survive hippopotamus attacks in Africa
each year compare with the percentage of
people who survive mosquito bites?
