Read the text trailer for the short story “4102 Elm Street.” Strange noises. Weird odors. No one seen going either in or out. Andrew knew something strange was going on in the house across the street, and he was determined to find out what it was. Armed with time, a map of the neighborhood, and a magnifying glass, Andrew set out to solve the mystery of 4102 Elm Street. Andrew had no idea what secrets he would find.

Which sentence would be most effective to add to the end of this trailer?

Even if Andrew did not discover any secrets at all, he decided to investigate because last summer was really boring.
In fact, only one thing was certain: This would either be the best summer of his life . . . or the worst.
Before he set out on his search, he decided to see if his best friend Oscar wanted to accompany him.
Luckily, in his search for answers, Andrew did not encounter any danger or come to any harm.
