Answer:
B. LOGOS
Step-by-step explanation:
Logos is a mode of persuasion, often used in speeches or persuasive writings, that uses reason, details, facts or logic. The excerpt uses this way of persuading because it gives facts and numbers: "The library renovations will cost the communities $1000 to build" and it appeals to reason when asserting that even though it costs a lot, it will make profit in the long-term, which is a common rule in businesses that go well: they first required an investment (done wisely) in order to profit later. This way, the speaker convinces people that the cost of the renovations will be worth it.
