PRACTICE QUESTION
Thursday, September 23rd, 2010
(For solutions, go to the HOME tab and scroll down.)
The questions are based on the following passage:
The ground is full of seeds that cannot rise into seedlings;
the seedlings rob one another of air, light and water, the
strongest robber winning the day, and extinguishing his
competitors. Year after year, the wild animals with which
5 man never interferes are, on the average, neither more nor
less numerous than they were; and yet we know that the
annual produce of every pair is from one to perhaps a
million young; so that it is mathematically certain that,
on the average, as many are killed by natural causes as
10 are born every year, and those only escape which happen
to be a little better fitted to resist destruction than
those which die. The individuals of a species are like
the crew of a foundered ship, and none but good swimmers
have a chance of reaching the land.
1. The “robber” in the first sentence is most like which of the following mentioned in the paragraph
A. wild animals
B. produce of every pair

2. The main point the author conveys is that
A. natural populations of animals in the wild increase in numbers exponentially
B. all members of a species are in violent competition with one another
C. in the struggle to survive, the fittest survive
D. members of one generation of a population are all more or less alike
E. man’s interference destroys the natural balance
