Point X shows where the shoes spilled into the ocean. James Ingraham used a computer program to predict where some of the shoes might reach shore and about how long it would take them. Dr. Curtis Ebbesmeyer is keeping a record of when and where people are actually finding the shoes. The scientists are comparing their information to learn more about ocean currents. Point on Map

A.2.4.1 1. Which detail from the passage supports the main idea? A The shoes were encrusted with barnacles and salt. B The cargo ship carried containers as large as train cars. C The shoes were washed ashore by reliable ocean currents. D The cargo included sneakers, sandals, and hiking boots. A.2.2.2 2. Read the following sentences from the passage. “He phoned beachcombers, including an Oregon artist, Steve McLeod. McLeod had collected information about when and where 1,600 shoes were found.” The word beachcombers probably means people who go to the beach to look for A places to sell food. B swimmers in danger. C interesting objects. D different kinds of birds. A.2.4.1 3. Dr. Ebbesmeyer learned that the shoes came from the Hansa Carrier by A using the identification numbers of the shoes. B following the currents that carried the shoes to shore. C asking for information from people in other countries. D developing a computer model to show how far the shoes drifted. !
A.2.5.1 4. Which is the best summary of the passage? A Containers fell overboard during a storm and spilled shoes. B Studying moving objects helps make computer models better. C Currents are like wide rivers in oceans and can infl uence weather. D Scientists are studying the drifting shoes to learn
!
A.2.2.2
5. The author writes that a computerprogram, or model, “simulates ocean currents.” The word simulates probably means A finds. B changes. C imitates. D measures. A.2.4.1 6. Dr. Ebbesmeyer believed the shoes scattered north and south because A large ships change the direction of ocean currents. B waves push floating objects in different directions. C ocean currents change direction close to the shore. D winds blow in different directions in winter and summer. A.2.6.1 7. The author most likely wrote this passage in order to A describe for the reader details about ocean storms. B persuade the reader to study objects lost from ships. C entertain the reader with a story about a ship in a storm. D inform the reader about scientists who study ocean currents.
