Joke of the Week: Car Privileges

A mother and father had just given their teenage daughter family-car privileges. On Saturday night she returned home very late from a party.

The next morning, her father went out to the driveway to get the newspaper and came back into the house frowning. At 11:30 AM the girl sleepily walked into the kitchen, and her father asked her, "Sweetheart, what time did you get in last night?"

"Not too late, Dad," she replied nervously.

Dead-panned, her father said, "Then I'll have to talk with the paperboy about putting my paper under the front tire of the car."

    (A) The deliberate degradation of the GPS signal 
    (B) The encryption of the P code transmissions
    (C) The licensing of all GPS receivers by the federal government
    (D) The shutdown of selected satellites by the control segment

Come back next week for the solution!
