Question ID:PT90 S4 Q20 Passage:Paula:  Earthlike planets seem to be the rule rather than the exception, so there probably are intelligent beings on other planets. Furthermore, we can expect our radio telescopes to detect signs of such beings. Alien scientists would have basically the same understanding of mathematics and physics that humans have. Thus they would inevitably discover gravity, electromagnetism, and other fundamental physical phenomena and then develop technologies such as radio communication. Ashley:  That is like saying they would inevitably have the same legal or political systems that humans do. Our science, mathematics, and technology are unique outgrowths of our physiology, cognitive makeup, and environment. Using radio telescopes to search for intelligent life is a waste of time and money. Stem:The dialogue provides the most evidence that Paula and Ashley disagree with each other about whether Correct Answer Choice:AChoice A:it is probable that there are intelligent alien beings who have developed radio communication Choice B:it is probable that there are intelligent alien beings who have the same legal or political systems that humans do Choice C:our technology is influenced by our cognitive makeup Choice D:there is likely to be intelligent life on other planets Choice E:scientists should spend more time and money on the search for intelligent extraterrestrial life
