Read the passage.The town council of Hopewell has proposed that the vacant lot at the end of Elm Street be converted into a parking lot. While this unused land may seem like a suitable location, the nearby residents have many objections. For example, the youth in nearby neighborhoods enjoy using the lot for recreation. Many pet owners appreciate the undeveloped land because it allows dogs a place to run. Adding cars and pavement to this cherished natural area would be a grave error. The town council should observe the lot and all its uses before taking action.

Gently and carefully, Wyke scraped the dirt until he found the three cables encased in black rubber and, he believed, pressurized by nitrogen, a common practice in the 1950s to keep moisture out of cables. He knew that once he cut through the rubber sheathing on the cables, the nitrogen would escape. The resulting drop in pressure would be detected by the Soviets. The engineers solved this potential problem by building a concrete barrier with a steel door to pressurize the tap chamber and separate it from the pre-amp room. (It turned out that the cables were not pressurized.)Wyke next attached wires to the exposed cable—probably with alligator clips—and began to draw power from the cables.
