Sandra and Markus are both reporters for the Williamsburg

Gazette. They have hated each other since elementary school.

Each always tries to outdo the other in sports, grades, salary, and

other achievements. One day, their boss tells them they have to

work together to investigate a company some residents believe

has been polluting the local river. Sandra and Markus agree to

work as partners, but they fight almost every day on the job,

hiding leads from each other, conducting separate interviews

with the same person, and sabotaging each other's work.

Which scenario would make the best climax for this story?
