The cosmic microwave background is a uniform 2.7 Kelvin radiation that permeates the entire universe. Although it was postulated almost 50 years before, Penzias and Wilson discovered the cosmic microwave background accidentally in the 1970s. Working at Bell Labs, these two scientists were using a radio telescope to observe distant stars. They found, however, that no matter where they pointed their telescope they observed an approximately 3 Kelvin background signal. After convincing themselves that this signal was real and not some artifact of their instrument, they consulted with a team at Princeton University that had been searching for the cosmic microwave background. The Princeton team confirmed what Penzias and Wilson had found. Apparently, Penzias and Wilson had accidentally stumbled upon the oldest observable relic of the early universe.
3. According to the passage, with which of the following would the author most likely agree regarding the discovery of Penzias and Wilson?
(A) It was not as important as the signal for which they were originally searching.
The passage says that they simply stumbled on the microwave signal NOT that was more important what they looking for or not. No comparison.
(B) The telescope belonging to Penzias and Wilson was more sensitive than that of the Princeton team.
No information about the sensitiveness of the machine
(C) Penzias and Wilson would not have discovered the cosmic microwave background if it had been more than 3 Kelvin in temperature.
The passage cites that the waves were approximately 3 kelvin which means that they could be more than three or LESS than three NOt only bigger than three
(D) Penzias and Wilson did not initially understand the implications of their results.
Correct
(E) Penzias and Wilson did not believe that their signal was real when they took their discovery to the Princeton team.
The passage says EXACTLY the contrary.
After convincing themselves that this signal was real and not some artifact of their instrument, They believe.........
Hope now is clear
