Even though apes are the only nonhuman creatures able to learn human language, no ape has ever used its human language skill-q to ask such philosophical questions as, "How am I different from all other creatures?" Therefore, philosophical thought is unique to humans.
The conclusion in the passage above relies on which one of the following assumptions?
Pr.1: Apes can learn Human language
Pr.2: But, Apes do not ask Philosophical questions.
Conc.: Therefore, Philosophical thought is unique to humans.
Pre-think: Our prethinking process says that author has assumed a connection or link between human language and expressing philosophical thoughts.
(A) Human language is unique to humans - Negating it implies that Human language is not unique or limited to humans, even that does not cancel the conclusion.
(B) Apes are incapable of thinking in human language - Even if they are capable of thinking in human language apart from learning it, we cannot say that they lack philosophical thinking process. It might be the case that they do not want to express them.
(C) Philosophical thought can be expressed only in human language - Seems correct. What if they express it in some other way such as by some kind of sign language or action or something like this.
(D) Speaking in human language is easier than thinking in human language - Even if it is difficult, they still can express it.
(E) It is more difficult to learn human language than to express philosophical questions - Same as D.
