The best addition to the rebuttal is this: 'In addition, nine of the twenty five top scientific breakthroughs in the last twenty five years came from space exploration'. This statement shows clearly that funds spent on exploration is not a waste at all and that humanity has benefited from space exploration as a result of scientific breakthroughs that had been recorded through it. The statement also implies that more benefits can still be derived from space exploration.
The answer should be C, "In addition, nine of the twenty-five top scientific breakthroughs in the last twenty-five years came from space exploration."
