Thank you for your question. These types of questions - flawed parallel reasoning - do not necessarily call for diagramming for proper solution. On this question, for example, I would not diagram, but instead look carefully at the terms of the stimulus.

The flaw generalizes from part to whole - although the various goods sold at food co-ops may be generally cheaper than the same goods sold at grocery stores, this does not mean that overall it is more economical to shop at food co-ops.

Likewise, the correct answer choice here engages in the same flawed method of reasoning. Just because each part (each bicycle) has a certain quality does not mean that we can aggregate as has been done in this answer choice.

Hope this helps! Please let us know if you have any additional questions.

Hi! I'm still a little lost on this. If store (A) is a co-op and has the same items at a less expensive price than store (B) (C) or (D), why can't we extrapolate that it is more economical to shop there?

I could understand if it said it has some items cheaper, but it seems to indicate that all items are cheaper?

Thanks for any clarification!
