Explanation:

Our day to day activities involves different level of strength and forve. High intensity activities are the ones which requires too much vigor and where a person feels breathless because of an increase in heart rate. For example: when we play football, our body constantly keep running from here and there consuming too much strength.

Moderate intensity activities are those which do increase our breathing and heart rate, but one can still be able to have a conversation and talk. Say for example: aerobics do increase our heart rate, but not to the point where we can't even talk.

Low intensity activities on the other hand are the activities which can be performed without much efforts. Casual walk, gardening, cleaning house are all low intensity activities.

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.
