Idk how about you look the question up on what's called the internet:)
Explanation:
<em><u>A) is giving money the best way to help</u></em>
Refugees are those who seek refuge or help. They travel to other countries because they fear for their lives. They wanted to live in a place where their human rights are not violated.
Migrants are those who decided to seek employment elsewhere. They leave their places of origin to look for work abroad. They do not leave in fear of their lives.
Refugees and Migrants are not the same when it comes to their reason of leaving their places of origin. But they should be given equal opportunities to better their lives in the place they chose to settle in.
Because the Europeans had already been exposed to the diseases and had built an immunity to it, and the Native Americans hadn't, hope this helps
