Some people have brought up cooking. Food preparation is a skill that students will use throughout their lives. For example, Youth Focus magazine reports that early culinary education is likely to help young adults live independently, reduce expenses, and even offer meals to friends and family. But the benefits of cooking classes go beyond learning to chop, mix, and sauté. In addition to building these skills, cooking lessons offer hands-on experiences that can help students understand other subjects such as nutrition, chemistry, and even math. Furthermore, classes can help break down boundaries by introducing students to foods from other cultures. Perhaps most importantly, though, cooking classes bring students together because they are fun -- and, of course, the results are delicious.

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.
