#TFQOD #MBA #CAT2014 Check out our Last Years Question of the Day: Answer the following based on the passage given below. That the universe is made of matter is obvious. What bothers physicists is why. Their best theory of universal fundamentals, known as the Standard Model, suggests that equal amounts of matter and antimatter should have been produced in the Big Bang. Famously, however, matter and antimatter annihilate on contact and disappear in a puff of pure energy. The reason that did not happen must be that matter and antimatter are not, in fact, perfect opposites—and that something in the asymmetry between them allowed matter to prevail. What that something is, therefore, is a question of great interest. Several groups of experimenters are searching for it and two of them, working at CERN, near Geneva, and Fermilab, outside Chicago, have just announced their latest results. Which of the following is/are the assumption of the experimenters working at CERN, Fermilab etc.? A. Universe could not have existed if there were equity between matter and anti-matter. B. Our world could not have existed if matter and antimatter were perfectly balanced. C. There is an unknown and fundamental particle that caused eh Big Bang. D. The standard model does not explain the existence of matter sufficiently. OPTIONS 1) A and D 2) B and D 3) A, B and D 4) A, B, C and D
