The correct answer is D. Sentence 2 provides supporting evidence for the reason stated in sentence 1.
Explanation:
In writing, a claim refers to a statement or assertion the author aims to prove through multiple reasons and evidence. In this case, the main claim is that "the government should limit the amount of sugar in sugary drinks" and sentences 1 and 2 have been provided to support it. In the case of Sentence 1 "Consuming too much sugar can lead to dangerous medical conditions" this sentence is a reason that supports the idea of limiting the amount of sugar, while sentence 2 "For example, people may develop obesity, tooth decay, or adult-onset diabetes" provides evidence by using examples of the illnesses sugary drinks can cause. This means sentence 1 is a reason and sentence 2 provides evidence or it or that "Sentence 2 provides supporting evidence for the reason stated in sentence 1".
