Question in-ord
In order to create the Global Positioning System (GPS), scientists had to develop an accurate mathematical model of Earth’s shape that accounted for various forces, such as tides. blank it was mathematician Gladys West who wrote the computer program that could perform these necessary calculations.

Answer explanation
Choice A is the best answer. "Ultimately" logically signals that West’s completion of the computer program was the conclusion of the process described in the previous sentence, in which scientists working on GPS sought to develop a mathematical model of Earth.
Choice B is incorrect because "in other words" illogically signals that the information about West’s program is a restatement of the information about the scientists’ efforts to develop a mathematical model of Earth. Instead, West’s program was the conclusion of those efforts. Choice C is incorrect because "secondly" illogically signals that West’s completion of the computer program was merely the next step in the scientists’ efforts to develop a mathematical model of Earth. Instead, West’s program was the conclusion of those efforts. Choice D is incorrect because "in addition" illogically signals that West’s completion of the computer program was merely additional information related to the scientists’ work on GPS. Instead, West’s program was the conclusion of the scientists’ efforts to develop a mathematical model of Earth.
