Answer:
In the sentence - Riding a bicycle to work doesn't just conserve fuel, it also contributes to a person's physical and mental well-being. The thing that is wrong with this text and visual aid is that the image of the cars doesn't relate to the information about bicycles in the text. So, the correct answer is Option C.
Explanation:
The use of "doesn't just conserve fuel” is wrong in this sentence. When the sentence is emphasising on the benefits of cycling to work it must be framed accordingly. The structure of the sentence is wrong which gives an impression of cars in the beginning.
Rather it should be “riding a bicycle to work not only conserves fuel, but also contributes to a person's physical and mental well-being.” The use of "not only...but also" in a sentence helps in stating the real meaning. It clearly conveys that one of the benefits of cycling is conserving fuel.
