Each of the following, if true, would weaken the

Answer choices

  1. Weakens9% picked this

    Anthropologists rely on inadequate translation techniques to investigate the values of cultures that use languages different

    Wow, right out of the gate, attacking the evidence rather than the reasoning. This weakens by making the anthropological study seem to have bad (inadequate) data. This hurts the argument by calling into question whether anthropologists have successfully determined that distinct cultures differ in their moral codes. After all, the anthro's are relying on inadequate translation techniques.

  2. Correct61% picked this

    As a result of advancing technology and global communication, we will someday all share the same culture

    Why this is right

    This doesn't help us argue that the anthropologists have given us bad data, nor does it help us argue that "even if each culture is distinct, there might still be some shared values". This is talking about a hypothetical world in which we "all share the same culture". It's irrelevant what would be true in that sort of world, since the author's conclusion is only about a world in which "there are distinct cultures".

    Skill tested: Weaken · how this choice captures the argument's function is the move to repeat next time.

  3. Weakens11% picked this

    Although specific moral values differ across cultures, more general moral principles, such as “Friendship is good, ” are

    This allows us to argue that even though each moral code is different, there are shared moral values. It's saying "the uniqueness of moral codes comes from their specifics, but there are more general principles/values that are common to all cultures".

  4. Weakens6% picked this

    The anthropologists who have studied various cultures have been biased in favor of finding differences rather than

    Just like (A), this weakens by hurting the credibility of the argument's evidence. This hurts the argument by calling into question how much we should trust anthropologists' studies saying that distinct cultures differ in their moral codes. After all, the anthro's doing these studies have been biased in favor of finding differences.

  5. Weakens13% picked this

    What appear to be differences in values between distinct cultures are nothing more than differences in beliefs about how to live

    This allows us to argue that even though each moral code is different, there are shared moral values. It's saying "the uniqueness of moral codes comes from how people interpret the best way to live in accordance with certain values, but all cultures are still coming from a starting point of shared values."
