Final answer:
Jasper is concerned with two aspects of quality while considering a lawn mower: reputation, which is informed by customer reviews, and service, which includes manufacturer-provided maintenance and repair.
Step-by-step explanation:
The aspects of quality that Jasper is considering while reading reviews and thinking about maintenance are reputation and service. Customer reviews on websites and blogs are an aspect of quality called reputation. These reviews help potential customers evaluate the product based on the experience of others, which contributes to the perceived trustworthiness and credibility of the product and the firm behind it. On the other hand, Jasper's concern about the maintenance of his lawn mower and his belief that the manufacturer is the ideal choice for maintenance and repair speak to the aspect of quality he is looking for, which is service. This includes after-sales support, availability of parts, and expertise in repair and maintenance offered by the manufacturer.
