The passage characterizes the main finding of the 2015 sea otter survey conducted by the US Geological Survey as

• initially promising, because it shows that the southern sea otter will not become an endangered species.

• very significant, because it validates the recent efforts of sea otter conservation groups working along the California coast.

• ultimately inconclusive, because it does not incorporate data from sea otter population surveys conducted before 2010.

• somewhat misleading, because it does not make it clear that the southern sea otter population trends varied throughout the range.

Which choice provides the best evidence for the answer to the question... The passage characterizes the main finding of the 2015 sea otter survey conducted by the US Geological Survey as?

• The first sentence of the first paragraph (“The recovery … Survey”)

• The first sentence of the second paragraph (“There’s … program”)

• The fourth paragraph (“While … areas”)

• The fifth paragraph (“Since … years”)

A researcher wanted to know if there is an association between exercise and sleep for the population of 16-year-olds in the United States. She obtained survey responses from a random sample of 2000 United States 16-year-olds and found convincing evidence of a positive association between exercise and sleep. Which of the following conclusions is well supported by the data?

• There is a positive association between exercise and sleep for 16-year-olds in the United States.

• There is a positive association between exercise and sleep for 16-year-olds in the world.

• Using exercise and sleep as defined by the study, an increase in sleep is caused by an increase of exercise for 16-year-olds in the United States.

• Using exercise and sleep as defined by the study, an increase in sleep is caused by an increase of exercise for 16-year-olds in the world.
