Final answer:
The underlined words should be written as 'Farmers and chefs around the world' to provide a more specific and credible support to the Slow Food movement.
Step-by-step explanation:
The underlined words should be written as 'Farmers and chefs around the world' so that sentence 2 has the right tone. The original sentence states that the Slow Food movement is supported by 'all kinds of people,' which is very general and vague. By specifying 'Farmers and chefs around the world,' it gives a more specific and credible support to the movement.
