Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.
May 2, 2000 saw a great improvement in the accuracy of GPS. Tens of thousands of GPS receivers were instantly upgraded. An announcement from the White House meant everyone’s ability to pinpoint their location or their item’s location. On May 3, a GPS enthusiast named Dave Ulmer tested this accuracy by hiding a navigational target in the woods. He placed a black bucket containing a logbook, a pencil, videos, books, software, and a slingshot in the woods near Beavercreek, Oregon near Portland. Next, he shared the waypoint with the online community. Within three days, two different people used their own GPS receivers to find the container and wrote about their experiences. The original idea was simple, hide a container and note the coordinates with a GPS unit. The rules for participants include ‘Take some, leave some.’ Various ideas were suggested in place of ‘stash’ before ‘geocaching’ was settled on.
