Answer 1

The statement is false; high-voltage wires are held by insulating connectors but are not wrapped in insulating material.

Step-by-step explanation:

The statement that high-voltage wires that you see connected to tall metal-frame towers are held aloft by insulating connectors, and these wires are wrapped in an insulating material is false. While it is true that the wires are held aloft by insulating connectors, which prevent the electricity from traveling down the towers into the ground, the high-voltage wires themselves are not wrapped in an insulating material. Instead, they are intentionally left bare. The air surrounding the wires serves as a natural insulator. Moreover, insulating the wires would be impractical due to the high cost of insulation materials for such long distances and the difficulty in maintenance and heat dissipation.
