Armchair anthropologists of the Victorian Era rarely visited the lands

The answer MUST be B. This is a good example of a GMAT CR question, because it follows the basic tenet of CR questions: if you keep your eye on exactly what's being claimed, the answer comes directly out of it.

In this case, the claim in the argument is as follows:
1) Victorian anthropologists did not go countries and called people "savages"
2) Contemporary anthropologists did go, and use the term "indigenous people".
3) The term "indigenous people" is more "enlightened" than the term "savages."

So what's the missing connection? Well, the people who went to the countries use the more enlightened term. There is NO other difference mentioned between the two sets of anthropologists, so the right answer MUST hinge on this difference. B simply makes this connection, clearly and accurately, and must be right. To test it, use the negation test:


If this were true, then the argument would not be true, because neither group would be any more likely than the other to be "enlightened" (or, more accurately, to use a more "enlightened" term).

All the other choices distort the entities in the argument in various ways, usually by moving the term "enlightenment" to the wrong entities in the argument (Victorian anthropologists, "savages," etc.) It is only contemporary anthropologists who are "enlightened."
