Final answer:
To determine the acceptability of reasoning by analogy using a representational analogy, you must assess the relevance of the similarities between the situations being compared and whether the analogy enhances clarity.
Step-by-step explanation:
In order for reasoning by analogy using a representational analogy to be acceptable, you must ask yourself whether the two situations being compared are truly analogous. This means considering whether the similarities between the situations are relevant to the argument being made. You should also assess whether the analogy helps make the point or argument more clear to you as the reader or listener.
