Read the passage and choose the best answer.
When Nick and Jane got their phone bill, they knew something was wrong. They couldn't understand why the new bill was over fifty dollars more than the old one. Then Nick saw the long-distance charges. There were ten calls listed to the town of Rosemont, several hundred miles away.
"But we don't know anybody in Rosemont," Jane protested. "Where is Rosemont, anyway? Besides, no one would have such a ridiculous phone number as 123-456-7890." Suddenly, they thought of their twin sons, who were just learning how to count. They must have been playing with pushbuttons on the dial. This turned out to be the right solution to the mystery of their phone bill.
