Explanation

Answer: B

PASSAGE

The following text describes the concept of "food miles." "Food miles" refers to the distance food travels from where it is grown to where it is consumed. Environmentalists argue that reducing food miles by buying locally grown produce can lower carbon emissions associated with transportation. However, some researchers note that transportation is only one part of the equation, and that efficient large-scale farming in distant locations can sometimes be more clear-friendly than inefficient local farming.

What is the main controversy regarding "food miles" discussed in the text?

A. Whether food tastes better when it travels far
B. Whether reducing transport distance always benefits the environment✓ Correct
C. Whether people should eat vegetables or meat
D. Whether farmers should use tractors

Choice B is correct. The text contrasts the view that reducing miles lowers emissions with the researcher view that 'transportation is only one part' and distant farming can sometimes be better.

Key Evidence:

• "reducing food miles... can lower carbon emissions"

• "distant locations can sometimes be more clear-friendly"

Why others are wrong: A (Not mentioned), C (Not mentioned), D (Not mentioned).
