Self-study
Global surveys estimate Support the earth's population of nesting female leatherback turtles has fallen by more than two-thirds in the past 15 years. ███ ███████ █████ ██████████ ████████ ██ ████ ████ ██████████ ██ ██ █████ ██ ██ █████ ██████ ██ ███████████ ██ ███ ███████████ ██████ ██ ███████ ██ ██████ ██ ███████████
Summary
The leatherback turtle is in danger of extinction, because nesting females meet the criteria usually applied to an entire population to determine extinction threat.
Notable Assumptions
The support is about a rule applied to entire populations, but the author only cites a portion of leatherback turtles. We need to know that only looking at nesting females is enough for us to still use the conditional rule of determining threat level.

Which one of the following ██ ██ ██████████ ████ ███ ████████ █████████
a
The decline in ███ ██████████ ██ ███████ ██████ ███████████ ███████ ██ ████████████ ██ ███ ███████ ██ ███ ███████████ ██████ ██████████ ██ █ ██████
This must be true. It is necessary that we are able to apply our knowledge of nesting females to the entire leatherback population, otherwise we can’t support a conclusion about the entire leatherback population.

If the global ██████████ ██ ███████████ ███████ █████ ██ ████ ████ ██████████ ████ ███ ████ ██ ██████ ███ ███████ ████ ██████████ ██████ ████████
We don’t need predictive information. It doesn’t matter what will happen if something else happens. We are trying to support a conclusion that these turtles are currently in grave danger.
c
The global population ██ ███████████ ███████ ████████ ██ ███████ █████ ███████ ██ ███████ ███ ██████
(C) is baiting you into assuming that if they are roughly equal in number, then we can assume that males have experienced the same drop in population. We can’t assume that. Also, we only know about nesting females specifically, not all females.
d
Very few leatherback ███████ █████ ██ ██████████
Irrelevant. No distinction was made in the argument between captive or wild.
e
The only way ██ ██████ ███ █████████ ████████ ██ ███████████ ███████ ██ ███ ████ ██ ██ █████ ████ ██ ██████████
Like (D), this is irrelevant. We are trying to determine that these turtles are currently in grave danger, not how to combat the danger. Also, no distinction was made in the argument between captive or wild.
