#21 - Only engineering is capable of analyzing the nature of

[Capetowner]

Hi, Studytime,

Good job analyzing this stimulus. There is in fact an argument, even if it is not obvious. The claim the author is trying to substantiate is that the analogy itself is valid.

You are correct to correlate the parts of the facts in the premises to the similar concepts in the proposed analogy.

Engineering : analyzing nature of machine as a whole :: Physiology : analyzing nature of body as a whole

The remainder of the claim is that based on the claim that the fact that Physics and Chemistry cannot express the notion of purpose is sufficient to know that they cannot by themselves ascertain operational principles.

There is an implied equivalence here between "notion of purpose" and "operational principles."

This is the most salient gap in the reasoning, expressed as you noted in Answer Choice (C): "Notion of purpose in engineering has an analog in organisms"

This analog refers to "operational principles." This is indeed an assumption necessary for this argument to be valid.

SO there are 2 kinds of analogies then? The 2-part as with this one (a:c:d) and the one-part like with "life is like a box of chocolates" ?
