Answer: A writer can look for whether a reason supports a claim when determining the relationship between them. Specifically, the writer should ensure that the reason provides logical support for the claim, such that it is relevant and believable. Additionally, the writer should consider whether the reason contains any potential problems or weaknesses that may weaken the overall argument. Finally, the writer should examine whether the reason requires any additional supporting evidence to strengthen the argument. While transition words can be helpful for indicating the relationship between ideas, they do not necessarily provide insight into the logical relationship between a reason and a claim.
