The authors of a recent article examined warnings of an impending wave of extinctions of animal species within the next 100 years. These authors say that no evidence exists to support the idea that the rate of extinction of animal species is now accelerating. They are wrong, however. Consider only the data on fishes: 40 species and subspecies of North American fishes have vanished in the twentieth century, 13 between 1900 and 1950, and 27 since 1950.
Which one of the following is the main point of the argument?
The main point of the argument can be found out by putting the whole argument on test with the statements presented in the options below. (A) There is evidence that the rate of extinction of animal species is accelerating.
Keep it.. As the presentation of the evidence was the main point which was contested in the argument. This option looks like a right choice.(B) The future rate of extinction of animal species cannot be determined from available evidence.
out of scope(C) The rate of extinction of North American fishes is parallel to the rate of extinction of all animal species taken together.
Looks like a trap. No where in the argument it is said that the rates are parallel, rather authors have declared that there is no evidence. # but we know there is(D) Forty species and subspecies of North American fishes have vanished in the twentieth century.
,Rephrasing an already presented information.(E) A substantial number of fish species are in danger of imminent extinction.
Yes they are, but where are the other animals. They must be taken into account if this argument is a conclusion
