Question

there are antennas and there are \antennae.\ satellite dishes installed on individual homes track television signals sent from satellites that are orbiting earth. these satellites are in the sky about 22,000 miles from earth. each satellite revolves around earth once every 24 hours, the same speed that earth turns. actually, the satellite keeps pace with earth. that is why a satellite dish placed on a home needs to be aimed only one time toward the satellite sending the signal. that is also why the dish is relatively small in size. the farther away the transmitting satellite, the larger the antenna that picks up the signal must be. if the satellite sending the signal were placed on the moon, the dish receiving the signal would have to be the size of a two - story house.
which assumption most likely motivated the author to write this passage?
space exploration is the primary driving force behind technological innovation.
increasing dependence on satellites will facilitate future space exploration.
people have become too complacent about technological advances resulting from space exploration.
human exploration of outer space will be made obsolete by the quality of information received from satellites.

Explanation:

The passage focuses on satellites and satellite - dishes, and how they are related to space exploration. It seems the author is interested in space exploration as the main driving force behind technological innovation related to satellites. The other options do not align as well with the overall theme of the passage.

Answer:

Space exploration is the primary driving force behind technological innovation.
