LR Question 15 Explanation

QUESTION TYPE: Flawed Reasoning
ARGUMENTS: Camille says that water saving faucets save less water than they claim.
Rebecca says that water saving faucets save water.
ANALYSIS: Rebecca totally blew it and failed to understand what Camille was saying.
Camille was saying something like “The manufacturers say you save 100 units of water. But actually, you only save 20 units of water.”
Rebecca: That’s not true! I save 20 units of water!
Rebecca utterly fails to address the claimed savings.
___________
- Neither person talks about cost of installation. They’re only arguing about water saved.
- CORRECT. Yup. Rebecca totally misses that Camille talked about whether you save as much as claimed. Saying “I saved some water!” doesn’t address how much the claimed savings were.
- Neither Camille nor Rebecca talked about possible inconsistencies across manufacturers. This is irrelevant.
- Customer satisfaction wasn’t addressed. The two of them are only arguing about the amount of water saved.
- This is a good assumption! If one faucet saves water, then putting the faucets in other places in the house would save even more water.
This has nothing to do with how much the manufacturers claimed you would save per faucet.

I don’t think your analysis is totally correct. Cost is being discussed. Camille states that “manufacturers of water-saving faucets exaggerate the amount of money such faucets can save”. The mistake is that Rebecca assumes that her lower water bills indicate savings in line with the manufacturers’ claims. A is thus a tricky answer choice. I would assume B is correct because Rebecca is explicitly basing her conclusion off her water bills rather than an a non-stated implicit assumption regarding faucet installation costs.
Thank, I should have written the cost of installation. They both talk about water costs but not install costs. I’ll update this.
Note: This is an old comment but I wanted to address the point.
