I believe the correct answer is: The two paragraphs provide
details about the solution that the previous paragraph introduces.
In this excerpt from “A Cooking Revolution: How Clean Energy
and Cookstoves Are Saving Lives” written by Chef Jose Andres, author uses the
one-sentence paragraph ("It's also why I'm proud to support an effort to
bring clean cookstoves and fuels to millions of people in developing countries")
as the base for the introduction of the solution, after which he places these
paragraphs to provide the details to the solution.
