Read the passage below and answer the question that follows. 'The rise of urban farming has provided numerous benefits to city dwellers.

Economically, urban farms can create jobs and stimulate local economies by keeping food dollars within the community.' Which of the following statements best expresses the main idea of the passage?

Answer: Urban farming offers a wide range of advantages for urban environments.

The correct answer is that urban farming offers a wide range of advantages.
