A.I. Explanation:

Option 1: "To replace traditional farming methods completely"

Explanation: The text does not suggest that urban farming aims to completely replace traditional farming methods. Instead, it focuses on how urban farming complements existing food systems by providing fresh produce in urban areas. This option misinterprets the text's intent.

Option 2: "To provide fresh produce and promote sustainability in cities"

Explanation: This option accurately reflects the main purpose of urban farming initiatives as described in the text. The text highlights that urban farming provides fresh produce to food deserts and promotes sustainability, making this the correct answer.

Option 3: "To increase the profitability of real estate investments"

Explanation: The text does not mention anything about increasing profitability for real estate investments. Instead, it emphasizes community engagement and sustainability, making this option irrelevant to the main purpose of urban farming.

Option 4: "To create large-scale employment opportunities"

Explanation: While urban farming may create some jobs, the text does not focus on employment opportunities as a primary purpose. It centers on providing fresh produce and promoting sustainability, thus making this option incorrect.
