Scenario Kenneth and Catherine Lohmann of the University of North Carolina

Multiple Choice

Scenario
Kenneth and Catherine Lohmann of the University of North Carolina explored the orientation or direction-finding abilities of loggerhead sea turtle hatchlings under varying magnetic conditions. Hatchlings were placed in a tank of water in a laboratory either in the natural magnetic field of the earth OR in a reversed magnetic field in which north and south were flipped. The researchers then measured the direction that the hatchlings swam. The experiments were carried out in the dark and at night since that is when most newly hatched turtles migrate from their sandy nests into the ocean.
-The results of the Lohmanns' experiments are most likely to be considered credible if

A) the Lohmanns are famous scientists.
B) the experiments were funded by a government grant.
C) the results were published in a peer-reviewed journal.
D) a great deal of time had been spent collecting hatchlings and running experiments.
