Think about convincing someone to donate blood to patients. Try writing three different analogies for that. Let's start by writing a generalization together; then, just try out a few different analogies from the generalization. Don't worry whether they all work, but be ready to analyze WHY they do or don't.

The correct answer to this open question is the following.

These are the three different analogies.

1.- "If people donate blood you are probably not only saving a human's life but an entire generation."

I think this sentence is good and could work because the meaning is that if every single one of us donates blood, we can help give life hope to thousand or millions of people who can breed the next generation on Earth.

2.- "If you donate blood is like mother nature sharing its waters to grow plant and threes. She gives them life."

This analogy has to do with how mother nature takes care of every living sentient on the planet, the way we could take care of other people in need, by donating blood.

3.- "Donating blood is like the Sun shining its rays of light over the Earth. It guarantees life for all."

This analogy tries to create awareness in that we could be "the sun" for other people who needs or "rays of life" or our living hope by donating blood.

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.
