Passage

Passage A One function of language is to influence others’ behavior by changing what they know, believe, or desire. For humans engaged in conversation, the perception of the most common vocalization stimulus.

While animal vocalizations may have evolved because they can potentially alter listeners’ behavior to the signaler’s benefit, such communication is—in contrast to human language—inadvertent, because most animals, with the possible exception of chimpanzees, cannot attribute mental states to others. The male Physalaemus frog calls because calling causes females to approach and other Many animal vocalizations whose production initially seems goal-directed are not as purposeful as they first appear.

Passage B Many scientists distinguish animal communication systems from human language on the grounds that the former are rigid responses to is spontaneous and creative.

In this connection, it is commonly stated that no animal can use its communication system to lie. Obviously, a lie requires intention to deceive: to judge whether a particular instance of animal communication is truly prevarication requires knowledge of the animal’s intentions. Language philosopher H. P. Grice explains that for an individual merely a conditioned reflex: animals may use communicative signs but lack conscious intention regarding their use.

But these arguments are circular: conscious intention is ruled out a priori and then its absence taken as evidence that animal communication is fundamentally different from human language. In fact, the narrowing of the perceived gap between animal communication and human language revealed by recent research with chimpanzees and other animals calls that animals respond mechanically to stimuli, whereas humans speak with conscious understanding and intent.

Your task

Pin down exactly what the question asks about the passage — a detail, the author's view, the structure, or the main point — before looking at the choices.

Common trap

Answers that restate a true detail from the passage but don't answer the specific question being asked.

Winning move

Anticipate the answer in your own words from the passage, then find the choice that matches that prediction.

Answer choices

  1. Wrong Objection15% picked this

    They fail to recognize that humans often communicate without any clear idea of their

    Psg B wants to say that Psg A fails to recognize that non-human animals perhaps do communicate with some idea of their listeners' mental states.

  2. Out of Scope: credentials2% picked this

    Most of them lack the credentials needed to assess the relevant

    The author is never talking about people not having the expertise to assess experimental evidence. Psg B is saying that the assumptions that go into interpreting are faulty, but that isn't connected to a lack of credentials.

  3. Contradicted: well-known evidence animals lie5% picked this

    They ignore well-known evidence that animals do in fact

    In psg B it's acknowledged that many thinkers like Psg A would argue that no (non-human) animal can use its communication system to lie. Psg B never directly contradicts that, and it certainly doesn't suggest there's any well-known evidence to the contrary.

  4. Correct69% picked this

    They make assumptions about matters that should be

    Why this is right

    This captures the negative vibe. We can support "they make assumptions" from the line that "these arguments are circular: conscious intention is ruled out a priori". "a priori" is a Latin term (I guess) that means, roughly, prior to even entering this conversation / examining this data. It comes from the old Nature vs. Nurture debate. How much of our minds is programmed by innate things (a priori) and how much is acquired through experience (a posteriori). So that first sentence of B's last paragraph is saying, "They begin with an assumption that animals don't have conscious intention and then conclude from that absence that animal communication is very different from human communication". The "should be determined empirically" is somewhat just the logical opposite of a priori, but it is also reinforced by the fact that B brings up what recent research has told us. In short, B is like, "Shut up psg A. You're just assuming animals don't have intention, but check the research instead of your ego-reinforcing assumptions. The empirical research suggests there's not this huge gap in communcation."

    Skill tested: Author Opinion · how this choice captures the passage's function is the move to repeat next time.

  5. Too Strong: all8% picked this

    They falsely believe that all communication systems can be explained in terms of

    Psg B never accused thinkers like Psg A of believing that all communication systems can be explained in evolutionary benefits. Also, psg B would probably agree with this (assuming that they're both scientists who believe in the theory of evolution), so she wouldn't say that psg A falsely believes that communication can be explained via natural selection.
