The data supports which of the following claims?
A. No animal gained or lost more than 50% of its body weight in one week.
B. The dog’s weight throughout the study was always at least 2 kg greater than the cat’s weight.
C. At least one animal weighed more at the end of the study than at the beginning.
D. At least one animal reached its maximum weight during week 3 of the study.
E. Each animal’s weight first decreased, then increased, then decreased again during the study.

Official Explanation
The hamster ’s weight changed from nearly 6 kg in week 1 to just above 2 kg in week 2, a change of over 50% in 1 week, so (A) is not correct.
The dog’s weight parallels the cat’s fairly closely throughout the study and is usually about 2 kg greater than the cat’s, except in week 4, when their weight graphs move closer together, showing that (B) is not correct.
Each animal had a lower final weight than starting weight, so (C) is not correct.
An examination of the week 3 weights for the animals shows that the dog did reach its maximum weight in week 3, so (D) is correct.
The dog’s and cat’s weights did follow the “decrease-increase-decrease” pattern throughout the study, but the hamster ’s weight simply decreased then increased, so (E) is not correct.
