The ................ go from Canada to the south of the USA.
(A) Great Lakes (C) Rocky Mountains
(B) Niagara Falls (D) Shetlands
My answer is (b).
Can you give me your answer please?
The Niagara Falls are on the border between the two, so they 'go from Canada to the USA' - but note that it says, "to the south of the USA." From the Canadian border to nearly the Gulf of Mexico?
Yes, it must be the Rockies.
