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: They were trying to scare each other. There was a sudden knock at the door. It was Jenna's mother who had forgotten her keys. Choices: a. The girls were scared. b. Jena and Macie were telling ghost stories. c. Brett is totally wasted and has a great time.
