After reviewing this question several times, I don't see how it is not flawed. Passage and question directly below, and my thoughts on why the Q is flawed below them.
Whether the languages of the ancient American peoples were used for expressing
abstract universal concepts can be clearly answered in the case of Nahuatl. Nahuatl,
like Greek and German, is a language that allows the formation of extensive compounds. By the combination of radicals or semantic elements, single compound words
can express complex conceptual relations, often of an abstract universal character.
The tlamatinime (those who know) were able to use this rich stock of abstract terms
to express the nuances of their thought. They also availed themselves of other forms of
expression with metaphorical meaning, some probably original, some derived from
Toltec coinages. Of these forms, the most characteristic in Nahuatl is the juxtaposition
of two words that, because they are synonyms, associated terms, or even contraries,
complement each other to evoke one single idea. Used metaphorically, the juxtaposed
terms connote specific or essential traits of the being they refer to, introducing a mode
of poetry as an almost habitual form of expression.
For the following question, consider each of the choices separately and select all that
apply.
1. Which of the following can be inferred from the passage regarding present-day
research relating to Nahuatl?
A Some record or evidence of the thought of the tlamatinime is available.
B For at least some Nahuatl expressions, researchers are able to trace their
derivation from another ancient American language.
C Researchers believe that in Nahuatl
--------------------------------
The "correct" answers are A and B, but shouldn't it only be A? B does not work, because although the Toltecs were indeed an ancient american civilization, the passage itself, which is the only source of information we should be using, does not say so; it only says that certain commonly used metaphorical expressions in Nahuatl culture were "original", meaning indigenous to the Nahuatal, or "derived from Toltec coinages". Since we are only supposed to use the information given in the passage to make an inference, we would not be correct to infer, even if we may actually know, that the Toltecs were an ancient american and not an ancient chinese, european, etc culture.
Or if I'm wrong, what on earth am I missing? It does strike me as very odd that the official guide would contain an error like that...
