A.I. Explanation:

Option 1: "To provide free workshops on gardening"

Explanation: While the text mentions that workshops on sustainable gardening practices are held every Saturday, this is not the primary goal of the Green Thumb Project. The workshops are part of the initiative but do not encapsulate the overall aim, which is to foster community engagement.

Option 2: "To bring the local community together"

Explanation: The text clearly states that the Green Thumb Project has brought the local community together like never before. This aligns with the main idea of the text, which emphasizes community involvement and shared purpose as the project's primary goal.

Option 3: "To bring the local community together"

Explanation: This option is identical to Option 2 and is also correct. The text highlights the project's success in fostering a sense of community, which confirms that bringing the local community together is indeed the primary goal.

Option 4: "To create educational programs for children"

Explanation: Although the text mentions plans for more educational programs, it does not specify that these programs are exclusively for children. Therefore, this option is too narrow and does not accurately reflect the primary goal of the project, which is broader in scope.
