Some studies of migrating animals measure how far the animals travel in a year by fitting individuals with GPS tracking collars. Other studies track annual round-trip distance (RTD), which is equal to double the distance separating the two habitats a population migrates between each year

A researcher argues that since GPS records all of an animal’s movements, using the GPS method to track a population would result in significantly higher recorded travel distances than using the RTD method would. For example, it’s very likely that the distance reported for the __________

Which choice most effectively uses data from the table to complete the example?

• A.

  caribou would be greater than 2,155 kilometers if the RTD method had been used.

• B.

  caribou would be less than 3,807 kilometers if the RTD method had been used.

• C.

  white-eared kob would be less than 400 kilometers if the GPS method had been used.

• D.

  white-eared kob would be greater than 3,807 kilometers if the GPS method had been used.
