XD the entire sentence was already filled in for me, I didn't need to do anything! Should I report it?
It keeps marking me wrong and tells me I should have written "The population of the America...."
I believe it should be "the United States," to differentiate it from the rest of the two American continents.
I think loĝantaro could also be translated as inhabitants.
There is the more direct translation "loĝantoj" for "inhabitants" ☺
The "da" in here somehow threw me off, & with the way most of the rest of this program is written, I thought it wanted an "of".
Aŭ, laŭ la eksprezidanto Bush "pli ol tricent homoj"
Technically correct ;D
