Experts studying patterns of shark attacks on humans have noted that attacks tend to diminish when the water temperature drops below 65 degrees Fahrenheit. Until recently, researchers believed this was because sharks prefer warmer water, and thus are present in fewer numbers in colder water. However, new research shows that sharks are present in equal numbers in cold and warm water.

Which of the following, if true, best explains the apparent paradox?

(A) In general, humans prefer warm water.

(B) Sharks' keen sense of smell is enhanced in cold water.

(C) In the Pacific, shark attacks tend to occur more frequently in the daytime.

(D) Of the more than 200 types of sharks present in the ocean, only three attack humans.

(E) The average temperature of the earth's oceans is 55 degrees.
