Let's decide a topic. What is the most important event or person in American history?

Does anyone have a good opinion?

What about the American president? If we know the president, we can understand the history easily!

Wow, that's a great idea!

Starting from the first president : George Washington ; Abraham Lincoln, the 16th ;

Franklin Roosevelt, the 32 nd ; John Kennedy, 35 th, and more.

There are many famous ones.

That's right! George Washington had led the victory in the revolutionary war and is known as

the father of the United States.

Lincoln was the one who ended slavery system in the American civil war.

And, there is a symbol of liberal democracy : John F. Kennedy.

Hmm. But over 40 presidents are just too many.

Is it really over 40? What a headache!
