Passage Summary: A store called Gahagan's sells a ton of plants, mainly to professional landscapers. They also sell garden tools, but those are mostly bought by regular people for their own yards.

Reasoning: The store sells a high volume of plants primarily to commercial landscapers, while it sells gardening tools primarily to individual home gardeners.

Analysis: In 'Most Strongly Supported' questions, we are looking for a small, safe inference rather than a grand conclusion. We have two distinct categories: plants (mostly commercial) and tools (mostly retail). If most plants are wholesale and most tools are retail, it is highly likely that the average home gardener shopping there is buying more tools than plants, or that the commercial buyers are responsible for the bulk of the plant volume. Avoid any answer that makes broad claims about all garden stores; stay focused strictly on Gahagan's data.
