I need to identify an example of an illusion in the passage below and explain it: Ben was a tireless worker. He was in the office everyday by 7 AM, and usually didn’t leave until we’ll after sundown. At 27, he was the youngest department head in the company’s history and was well on his way up the corporate ladder. Then one night he came home to find that his wife and his children were gone. Suddenly, his career didn’t seem so important anymore.
