Point at IssueDiff: Easy

Logic Breakdown

Passage Summary: Carolyn thinks a portrait has to look like the person, so DNA in a jar doesn't count. Arnold thinks DNA is the ultimate portrait because it's the literal blueprint of the human being.

Conclusion: Carolyn concludes the DNA fragments are not a portrait, while Arnold concludes they are a maximally realistic portrait.

Reasoning: Carolyn argues that a portrait must visually resemble the subject. Arnold argues that because DNA contains the instructions for the subject's creation, it is the most realistic representation possible.

Analysis: To identify the point at issue, we apply the Agree/Disagree test. Carolyn explicitly states that a portrait must bear a 'recognizable resemblance,' which the DNA fragments lack, so she would say 'No' to the object being a portrait. Arnold says 'I disagree' and calls it a 'maximally realistic portrait,' so he would say 'Yes.' The disagreement centers on whether visual resemblance is a necessary requirement for something to be considered a portrait. Look for an answer that pits Carolyn's visual requirement against Arnold's informational requirement.

Correct Answer
E
E captures the direct point of disagreement. Arnold explicitly claims it is a (maximally realistic) portrait. Given Carolyn’s criterion and the nature of the object, she is denying it’s a portrait. So one says yes and the other no.
