In 1990, 80,000 pairs of Nike athletic shoes fell off a ship in the Pacific Ocean.
Ocean scientists were very interested when they heard about this. They asked
anyone who found a pair of these shoes to report the finding so they could learn
where the shoes landed. In all, 1,300 pairs of shoes were reported along the coast of
the United States and Canada. These reports gave the scientists important
information about
a. certain rare sea birds over the Pacific Ocean.
b. the movement of ocean currents.
c. how to get free shoes.
d. shipping routes in the Pacific Ocean.
