Answer:
The correct answer is B. Biofuels transferred over 100 million tons of cereals from plates to petrol tanks: to fill a 4 x 4 tank requires enough grain to feed a poor person for a year.
Explanation:
In Aristoletian rethoric, <u><em>Logos</em></u> refers to the world of logic and reason. The message is reinforced by reason. For this purpose, we use objective information and data, supporting the argument with numbers and statistics; making direct reference to research, studies, and experiments; showing provable facts.
In contrast, <em><u>Ethos</u></em> refers to the credibility of the speaker, and <em><u>Pathos</u></em> relies on the emotions generated by the message and choice of words.
From the provided options, A, C, and D appeal to Ethos by refering to experts, and to Pathos by using words and phrases with a strong emotional charge, such as "nightmare scenario," "thin edge between hope and hunger," and "a threat to global growth and social stability."
Option B, however, focuses on the facts related to biofuels, the amount of grain required to fill a tank, and its feeding capabilities. All of these are provable facts.
