Question

conrad is preparing a debate speech about how landfills are not sustainable, which he will use as his opening argument in an upcoming competition. what is the best introductory sentence for his argument? a. these days, people throw far too much trash away instead of mindfully recycling. b. the institute of the earth reports that american are not aware of their local landfills. c. you may not know that the average american produces seven pounds of trash per day. d. climate change shows us that burning trash is not a long - term solution to our trash problem.

Explanation:

The best introductory sentence needs to directly set up the argument that landfills are unsustainable by establishing a concrete, attention-grabbing fact about trash production that ties to landfill strain. Option A focuses on recycling, not landfills specifically. Option B centers on awareness, not landfill unsustainability. Option D discusses burning trash, not landfills. Option C provides a specific, striking statistic about daily trash output, which directly supports the need for sustainable waste management (and thus the unsustainability of landfills) by showing the sheer volume of trash that would end up in landfills.

Answer:

C. You may not know that the average American produces seven pounds of trash per day.
