Which one of the following most logically completes

Answer choices, explained

  1. Unrelated to Goal6% picked this

    birds do not respond in a predictable manner to signals

    This doesn't sound anything like our author saying, "These studies don't provide compelling evidence that song-overlapping is aggressive". It sounds like a Necessary Assumption the author's premise contains. But the conclusion needs to arc back to the various studies, or to this "aggressive" interpretation of song-overlapping.

  2. Too Strong: no insight8% picked this

    receiver-response tests can provide no insight into

    This is way too strong an idea. The author is saying he doesn't fully trust receiver-response tests, but saying they have zero value is too harsh.

  3. Unproven vs. Proven Unlikely8% picked this

    song overlapping is likely not a signal

    This is tipping into the flawed territory of "Because your evidence sucked, we know you're wrong". The author is only establishing, "Your evidence was weak or nonexistent." So she's only allowed to conclude something moderate and agnostic like, "Your evidence definitely doesn't convince me that this is an aggressive behavior." But we have no evidence to argue that it probably isn't an aggressive behavior, as this answer is doing.

  4. Too Strong: no function1% picked this

    song overlapping has no communicative

    Remember to treat Logical Completion like it's Most Supported. The more conservative the language is, the safer an answer choice. This has very extreme language — song-overlapping has zero purpose. Our author hasn't made a case for such a strong claim.

  5. Correct77% picked this

    the conclusion of these studies is

    Why this is right

    This is our moderate, agnostic rebuttal. - Your evidence was insufficient. - We'll have to wait for better evidence than what you've got to decide whether that claim is true. - It would be premature to draw that conclusion based on the existing evidence. Etc.
