The passage is an example of deductive reasoning because:
The author is starting with a general topic and moving to more.
The author starts by saying that food prices have risen and ends by concluding that the poor will be the most affected by this occurrence. Deductive reasoning is also thought of as top-down logic, which means that one starts with the more general claims and works one's way down to specific claims. It differs from inductive reasoning, in which one starts with specific claims to reach a general conclusion. The author aims to be objective by stating facts rather than opinions and is not appealing to his audience's feelings.
