Answer:
America
Step-by-step explanation:
Hello, given the topics 'Uncle Sam, U.S Constitution, Washington, ..."
We would deduce that out of the four choices, the best one would be America.
Veteran's day is a holiday observed in honor of those who have fought for American freedom; regardless if they are surviving or deceased. Therefore, if it were VD, the topics would perhaps describe the holiday and its purpose.
It would not be Apple Pie, considering the topics for this dessert would perhaps depict its taste or appearance.
Furthermore, it would not be Canada, considering Canada has different leaders and a somewhat differing past than the United States. What also eliminates Canada is the key idea 'US Constitution'.
Hence, it would be proved that the best choice is America.
Hope this helps.
