Answer 1

that the war would cost American lives

Step-by-step explanation:

Most Americans understood before their country entered World War I that the war would cost American lives.

Answer 2

None of the options here are good.

Step-by-step explanation:

American public opinion was divided and there were many views before the war.

The US joined the Allied effort, so nobody thought it could win alone.

Economic benefit was never a major thinking current in public opinion in the USA.

People didn´t expect their country to suffer so many casualties, but that a country will suffer causalties if it enter a war is obvious.

When the US entered WWI, the conflict had been going on for 3 years already, so people could not expect the war to be short-lived.
