Shark Attacks

by coolanubhav2002 » Sat Oct 27, 2012 3:01 am
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.

First of all please grey out OA..

B) dosn't resolve the paradox. It weekens the argument dosn't say why?
D and E are irrelevant
C says attack happens in day time..considering it to be warm for daytime.. if attack happens in day time then it dosn't give any evidence why?

A) says no of humans are more in warm water so even if no of sharks are same in both warm and cold water... more no of humans gives us the evidence that there is more likelihood of attack in day time

A should be correct.
