The first question asks of the united states dollar. It is green, which is verde in Spanish.
The second question asks of dimes and nickels, they are silver, it means plata but is AKA plateado
The third asks of our flag. It is red and white with a blue box in the top left corner that has 50 white stars.
The fourth question asks about the flag of Peru, it is mainly red and white, like the U.S.A's, except it also has a symbol in the middle with more colours like orange and green. I doubt the question is asking for these, though.
