In this task, you're given the title and three arbitrary sentences out of a five-sentence story. You are also given three additional sentence options, a, b, and c, that may or may not belong to the story. Your job is to pick the two options that seamlessly connect with the rest of the story; note that the selected choices may fit into the story at any point. Indicate your selected choices in order, i.e., as 'ab'/'bc'/'ac' and not as 'ba'/'ca'/'cb'. If options are equally plausible, pick the ones that make more sense.

Title: He hit a hard pothole. The jolt made his airbag deploy. Sam sued the car company for his medical bills. Choices: a. Sam was driving down the road. b. She hit another car while trying to park. c. The airbag almost broke his nose.
