Hi there!
Naturalization is the process of giving citizenship to a foreigner of a country.
Hope this helped!~
The early 1800s saw the United States quickly grow in size. New immigrants and new land meant a bigger and stronger country.
You didn't really provide any options here but we can safely say that Alexander's army (if you're talking about the army of Alexander the Great) was alert because they were trespassing in foreign terain where they could be attacked at any time.
I'd say more likely B. As i've gotten older i've realized the sad truth that a lot of people don't learn from their mistakes. And even if cops were perfect there will still be those few people who decide not to listen.
