Is the following definition of dog reversible? if yes, write it as a true biconditional.. a dog is a mammal. (1 point). a) the reverse is false.. b) the reverse is true. an animal is a dog if (and only if) it is a mammal.. c) the reverse is true. an animal is a mammal if (and only if) it is a dog. d) the reverse is true. if an animal is a dog, then it is a mammal.

A) The reverse is false.

A dog is a mammal which means that is a vertebrate animal, is warm-blooded, the mammal females have mammary glands, and newborns can be nourished with the milk that comes out of those glans, etc.

However, in this sentence, a reverse would be just wrong because a mammal is not the definition of a dog. The class Mammalia includes a variety of animal species that have some common characteristics, like the mentioned above, and many others that are distinctive in their species. Some other mammals include cats, whales, elephants, horses, giraffes, camels, cheetahs, and beavers.

the speech this question is referring to is president kennedy's special message to the congress on urgent national needs, may 25, 1961

kennedy responds in a very direct and concrete way to those thinking that communism is a positive system:

"yet their aggression is more often concealed than open. they have fired no missiles; and their troops are seldom seen. they send arms, agitators, aid, technicians and propaganda to every troubled area. but where fighting is required, it is usually done by others--by guerrillas striking at night, by assassins striking alone--assassins who have taken the lives of four thousand civil officers in the last twelve months in vietnam alone--by subversives and saboteurs and insurrectionists, who in some cases control whole areas inside of independent nations." (kennedy)

president kennedy presents communism as cowardly, as a hidden and treacherous weapon that strikes from the shadows like thieves, he represents the system as not even being capable of showing and open and overt attack or confrontation. to finish up the response, he expresses that the system attacks even a country's idependence and freedom.
