PrepTest 53, Section 2, Question 9
Global surveys estimate the earth's population of nesting female leatherback turtles has fallen by more than two-thirds in the past 15 years. Any species whose population declines by more than two-thirds in 15 years is in grave danger of extinction, so the leatherback turtle is clearly in danger of extinction.

Which one of the following is an assumption that the argument requires?
The decline in the population of nesting female leatherback turtles is proportional to the decline in the leatherback turtle population as a whole.
If the global population of leatherback turtles falls by more than two-thirds over the next 15 years, the species will eventually become extinct.
The global population of leatherback turtles consists in roughly equal numbers of females and males.
Very few leatherback turtles exist in captivity.
The only way to ensure the continued survival of leatherback turtles in the wild is to breed them in captivity.
