A.I. Explanation:

Option 1: "identifies simple ways to streamline our daunting fast- paced lifestyles."

Explanation: This option suggests that the book focuses on streamlining lifestyles, but the text emphasizes breaking down commitments into smaller tasks rather than simplifying lifestyles directly. The main idea is about making commitments manageable, not necessarily streamlining them.

Option 2: "attempts to break a seemingly overwhelming objectives into smaller achievable steps."

Explanation: This option accurately reflects the main idea of the text, which discusses taking a large commitment and dividing it into 365 smaller commitments. This aligns with the book's approach of making environmental actions more manageable and achievable.

Option 3: "suggests that major tasks should be undertaken in one unified program of action."

Explanation: This option contradicts the text, which advocates for breaking down commitments rather than undertaking them as a single unified program. The text emphasizes small, individual commitments rather than a comprehensive approach.

Option 4: "locates the key dates pertaining to the environmental movement."

Explanation: This option is incorrect as the text does not mention key dates or a timeline related to the environmental movement. Instead, it focuses on practical activities and commitments for going green.
