A.I. Explanation:

Option 1: "To organise community fairs and educational events"

Explanation: While the project does culminate in a community fair and includes educational components, these are not the primary goals. The main focus is on increasing the bee population, not merely organizing events.

Option 2: "To educate residents on planting wildflowers"

Explanation: Although educating residents is part of the initiative, it specifically relates to the importance of bees and biodiversity rather than solely on planting wildflowers. Thus, this option is too narrow.

Option 3: "To increase the local bee population"

Explanation: The text clearly states that the primary aim of the Green Ribbon Project is to increase the local bee population by planting wildflowers. This goal is emphasized as the main focus of the initiative.

Option 4: "To involve schools in environmental initiatives"

Explanation: While local schools are participating in the project, the primary goal is not to involve schools but to increase the bee population. This option misrepresents the main objective of the project.
