Sample Questions
Use the following information to answer question 14.
Population ecologists Roman Biek and Mary Poss of the University of Montana have
been using the presence of a cougar virus (FIV) to track the cougars’ movement and
family history.
Researchers often look at an animal’s DNA to track genetic change, but in slowbreeding, long-lived animals such as cougars, changes occur at a much slower rate
than environmental changes. That’s where a virus like FIV can help.
FIV seems to have no negative effects on cougars, although it infects a large
proportion of individuals in wild populations. It is passed from mothers to kittens and
is most likely transmitted among other individuals through mating and fighting. Since
FIV DNA mutates quickly—changing its sequence about
one per cent per decade (1% per 10 years)—FIV is becoming a good indicator of the
cougars’ movements throughout the Rocky Mountains.

Use the following letter from World War II to answer question 74.
Sir:
Some recent work by E. Fermi and L. Szilard, which has been communicated to
me in manuscript, leads me to expect that the element uranium may be turned into a
new and important source of energy in the immediate future….I believe, therefore,
that it is my duty to bring to your attention the following facts and recommendations.
In the course of the last few months, it has been made probable—through the
work of Joliot in France as well as Fermi and Szilard in America—thus it may
become possible to set up nuclear chain reactions in a large mass of uranium, by
which vast amounts of power…would be generated. Now it appears almost certain
that this could be achieved in the immediate future.
This new phenomenon would also lead to the construction of bombs. A single
bomb of this type, carried by boat or exploded in a port, might very well destroy the
whole port together with some of the surrounding territory.
I understand that Germany has actually stopped the sale of uranium from the
Czechoslovakian mines which she has taken over. That she should have taken such
early action might well be understood on the ground that the son of the German
Undersecretary of State, von Weizsacker is attached to the Kaiser Wilhelm Institute
of Berlin, where some of the American work on uranium is now being repeated.
Yours very truly,
A. Einstein
