Read the passage.
Jeremy's mother had been a professor at the state university for as
long as he could remember. Each semester proceeded the same as
the last. She taught classes three days a week and had extended time
off in the summers, which enabled her to spend extra time with her
children. Jeremy loved his summers with his mother, who was
adventurous and fun-loving. This predictability made it all the more
surprising when Jeremy's mother announced one spring day that she
was applying for a job as a CEO of a well-known corporation.
