Do you know what the choices are?
Answer:
B) He knew there would be a war with Mexico over Texas
Explanation:
Your two choices (after using process of elimination) are A and B. The answer is more likely A than B. This is because, after the civil war there was an abundance of unemployed people who probably preferred not to work in the south anymore, so they migrated north and many landed in New York. If I had to guess it was because it was a port city but there were many other things as well.
Hope this helps.
