Communication Satellites by Carmen Atwell 2 Select the correct answer. Which evidence from the passage best supports the claim that before communication satellites existed, people could only send signals over short distances? OA. "Unlike other man-made satellites, communication satellites remain stationary, which allows them to transmit signals in that area." Today, it is hard to imagine a life where people are not surfing the Internet, watching television, or using their cell phones to call or send text messages. However, none of these activities were possible before the existence of communication satellites. These satellites have made it possible to watch television and use devices like laptops, tablets, cell phones, and more. Before the use of satellites, transmissions were difficult or impossible for long distances. Signals, which travel in straight lines, could not bend around Earth to reach a destination far away. Because satellites orbit Earth, signals are sent immediately into space and are then redirected to another satellite or are sent directly to their destination. Unlike other man-made satellites, communication satellites remain stationary, which allows them to transmit signals in that area. The area to which the communication satellite can transmit signals is called a satellite's footprint. Communication satellites are important for remote areas that do not have access to B. "The area to which the communication satellite can transmit signals is called a satellite's footprint." OC. "Signals, which travel in straight lines, could not bend around Earth to reach a destination far away." D. "Today, it is hard to imagine a life where people are not surfing the Internet, watching television, or using their cell phones to call or send text messages." Reset Next 1 53 © 2021 Edmentum.
