23. Farm animals have certain behavioral tendencies that result from the evolutionary history of these species. By imposing on these animals a type of organization that conflicts with their behavioral tendencies, current farm-management practices cause the animals more pain and distress than do practices that more closely conform to the animals’ behavioral tendencies. Because the animals tend to resist this type of organization, current practices can also be less efficient than those other farm-management practices.

If the statements above are true, which one of the following can be properly inferred from them?

(A) Some of the behavioral tendencies of farm animals can be altered by efficient farm-management practices.

(B) In order to implement efficient farm-management practices, it is necessary to be familiar with the evolutionary history of farm animals.

(C) In order to create farm-management practices that cause less pain and distress to farm animals, a significant loss of efficiency will be required.

(D) Farm-management practices that cause the least amount pf pain and distress to farm animals are also the most efficient management practices.

(E) Some changes in farm-management practices that lessen the pain and distress experienced by farm animals can result in gains in efficiency.

答案：E
