Questions refer to the passage below.
"The island is divided into three sorts of men . . . Masters, Servants, and Slaves. The slaves and their posterity, being subject to their masters forever, are kept and preserved with greater care than the servants, who are theirs but for five years, according to the law of the island. So that for the time, the servants have the worse lives, for they are put to very hard labor, ill lodging, and their diet is very slight. . . .
"It has been accounted a strange thing, that the negroes, being more than double the number of Christians that are there . . . should not . . . become masters of the island. But there are . . . reasons that take away this wonder: one is, they [cannot] touch or handle any weapons; and that they are fetched from several parts of Africa who speak several languages, and by that means one of them understands not another."
