I am not sure this is a question, it is a statement.
I think that maybe people are saying different answers because there might have been many such laws. I will mention one example: the Diversity Visa Immigration: it means that people from Eastern Europe have a higher change of obtaining a visa due to a smaller population in the US than the western European Countries.
Ummmm....what's this for???
I think the correct answer from the choices listed above is option D. The tactic that Charles Townshend use to increase British control of the American colonies would be that created new taxes on the American colonists to raise revenue. Hope this answers the question.
I would say the answer is three (not 100% sure tho). It's definitely not 2 or 1
