Universities have long been instrumental in generating knowledge and ideas. But in an increasingly globalized world, and in the face of rapid scientific change, they will need to think about a set of new challenges and how best to prepare their students for the coming decades. Universities will need to teach a new kind of literacy, in which global awareness will play an important role. They also need to deal with the dilemmas posed by the accelerating pace of change brought on by scientific and technological advances. We are on the brink of once-in-human-history progress in combating disease through the application of modern science. Doctors will have at their disposal blood tests that will tell you with substantial predictive power how long you will live and from what diseases you are likely to suffer. The Internet and the application of information technology may well represent the most profound change in the way knowledge is disseminated since the printing press. We are close to understanding the first second of the history of the cosmos.According to the passage, universities are under an obligation to ensure that their students ----.Deselect Answer have the chance to work alongside foreign students are equipped to deal with the changing conditions of the coming decades are introduced to international perspectives in every area of study are taught not specific facts as much as broad ways of thinking all have a good grounding in science and technology None Q. 18 One point that is given considerable emphasis in the passage is ----.Deselect Answer the need of all students to get acquainted with foreign cultures and global issues that the universities have a commitment to the pursuit of truth for its own sake that the universities are in a position to further greater global integration the incredible speed with which knowledge is increasing that universities must stick to the values that have made them successful in the past None Q. 19 It is clear from the passage that science and the application of science ----.Deselect Answer will not help to further global awareness is largely confined within the universities has grown so complex that it is beyond the understanding of all but a very few cannot go on advancing at this rate is opening up startling new possibilities None Q. 20 The writer of the passage seems convinced that the current rapid developments in science and technology ----.Deselect Answer will be accompanied by new problems cannot go on much longer will bring more harm than good are largely concentrated in the field of medicine are beyond the grasp of most people in most countries None Q. 21 The phrase, “once-in-human-history progress” is saying ----.Deselect Answer we cannot expect or, indeed, hope for such progress ever to happen again this is only the first of many spurts of progress this is the first instance of a widespread application of science there has never been such progress ever before and there may not be again this is the highest possible peak of progress None Q. 22 Fact 1: Some pens don’t write.
