Taylor: Researchers at a local university claim that 61 percent of the information transferred during a conversation is communicated through nonverbal signals.
Taylor's Claims
1. Researchers at a local university claim that 61 percent of the information transferred during a conversation is communicated through nonverbal signals.
2. This claim is suspect
3. All such mathematically precise claims are suspect
4. Claims of such exactitude could never be established by science
Sandra's Responses
1. Does she argue that researchers didn't claim such a thing? No, she has no commentary about the local university study.
2. Does she argue this 61% claim is not suspect? No, she never directly talks about what share of conversation is conveyed via nonverbal signals.
3. Does she argue that some mathematically precise claims are not suspect? Yes, she is saying that many scientific disciplines obtain extremely precise results, which shouldn't be doubted just because they're precise.
4. Does she argue that claims of such exactitude can sometimes be established by science? Yes, she says that many scientific disciplines to obtain extremely precise results.
Evaluate
We can tell that Sandra isn't addressing the first sentence of Taylor's statements, since nothing she says overlaps with that claim.
She seems to really be addressing an underlying assumption of Taylor's second sentence. Taylor is saying that precise claims should be doubted because science can't establish claims of such exactitude.
Sandra is saying,
Goal
Let's look for an answer about whether or not science ever establishes extremely precise/exact claims, or about whether a claim being very precise is sufficient grounds to be suspicious of its truth.
