Answer:
One consistency in the text is "The balance beam is my favorite event to watch because it requires a great deal of focus."
Explanation:
The line "The balance beam is my favorite event to watch because it requires a great deal of focus." is inconsistent with the text because the story suddenly changes from 3rd person to 1st person. When writing a story about something, you shouldn't abruptly mention your opinion/belief on something, even if it's related to the story.
