In this task, you're shown a three-part story, with a beginning, middle, and ending. Your job is to slightly modify the middle part, so that the whole story becomes unlikely, improbable, or inconsistent. Generated sentences must minimally alter the given middle, with at most 4 new words added/existing words removed. Your sentence should be grammatically and syntactically correct. Also stick to the context of the given story. For example, if the story talks about "doctors", you can talk about "health" or "diagnosis", but don't mention "aliens". Avoid introducing any extra/irrelevant information, and use names instead of pronouns (e.g. he / she) wherever possible. Avoid simply negating the original middle, for example:  "She likes cakes." is changed to "She doesn't like cakes."

Example Input: Beginning: Julie decided to go for a hike. Middle: She lost track of time. Ending: She had to hurry to make it back before sunset.
Example Output: She found track of time.

Example Input: Beginning: Tom really wanted to learn to tap dance. Middle: Tom went to a dance school. Ending: Tom won the tap dancing competition and was very happy!
Example Output: Tom couldn't go to a dance school.

Example Input: Beginning: Yesterday was Mark's birthday. Middle: Everyone surprised him on his birthday. Ending: When he got to the party, he was very happy.
