The correct answer is options 1 and 3.
Indeed, option 2 is an established fact (It was announced by POTUS Barack Obama on June 15, 2012). Option 4 is also an established historical fact (Nikola Tesla, Elon Musk, Wernher von Braun and the list goes on and on and on). Option 5 is a false claim as foreign nationals are defined by the US Congress as “an individual who is not a citizen of the United States or a national of the United States (as defined in section 1101(a)(22) of title 8) and who is not lawfully admitted for permanent residence, as defined by section 1101(a)(20) of title 8).
Finally, claim number 1 is debatable since it is clear that it is an extremely complex issue and Americans are quite torn on it for a myriad of reasons. Claim number 3 is also debatable since lots of contradicting information exist and many times such studies are biased in favor or against immigration.
