This critical thinking question is from Chapter 12 in your textbook:

In May 1990, a container ship called Hansa Carrier encountered a storm in the North Pacific at about 48° north latitude, and lost 21 containers overboard, five of which contained 80,000 Nike shoes. The shoes carried serial numbers that identified them as being from the containers. By the end of 1990, shoes were washing up on Vancouver Island, British Columbia, and Oregon. By the winter of 1991, shoes were appearing on Hawaiian beaches.

Using Figure 12.11 in the textbook. Answer the following questions:

Which ocean currents were most likely to have transported the shoes?
