In this task, you're given the title of a five-sentence story, the first four sentences, and two options for the fifth sentence as a and b. Your job is to pick the sentence option that does not connect with the rest of the story, indicating your choice as 'a' or 'b'. If both sentences are plausible, pick the one that makes less sense.

Title: Bank.. Sentence 1: One day I had to get money at an ATM. Sentence 2: I couldn't find one so I just went to the bank.

He told me that he would drive me home and we'd try again later. b. On my way home I called my mom and told her it went well.
