Well, personally I think cheating is wrong right of the bat, whether it be on a test or in a game. Although it is wrong, almost everyone has done it. In Mr. Ross's situation, I probably would have told on the student, because the way he was cheating, by taking advantage of that man, was just plain rude. (It really bugs me when people take advantage of other people).
If the situation was different, and I was a new student at the school, and the kid who was cheating was the most popular kid in school, then I probably wouldn't have told on the kid, in fear that I would not make any friends.

Animal Jail
There are several different animals whose domestication has been tried, and failed. Think zebras, cheetahs, grizzlies, etc. What are three different reasons a species might resist domestication? Explain, and give an example of each one. This section begins on the bottom of page 168.
There are three main reasons that a species might resist domestication, Diet, Growth Rate, and Problems with Captive Breeding.
Diet- When feeding an animal, the conversian of food biomass to the consumer's biomass involves an efficiancy of around 10%. Basically 10,000 pounds of corn can feed an animal, who's size is 10% of the amount of food they are consuming. To feed carnivores it is especially hard, because we would have to provide the animal with 10,000 pounds of meat to reach a size of only 1,000 pounds.
Growth Rate- Animals must be able to grow quickly. Two animals which would immediatley cross elephants and gorillas of the list. It would take at least 15 years for an elephant or gorilla's herd to reach only adult size.
Problems of Captive Breeding- To me, captive breeding is one of the greatest problems with domestication. Though we may not be aware of it, many animals are uncomfortable when having to mate under forceful conditions, or while being watched by groups of people. This was the main reason why we are not able to domesticate cheetahs. When captive, cheetahs have been known not to reproduce do to the methods of attracting mates. In the wild, the male would usually chasethe female for many days. The female would become sexually receptive and the two would mate. Being in a cage eliminates that routine.
