Xavier Aptitude Test 2012 Solved Paper

DIRECTIONS (QS. 30-31) : Read the following passage and provide appropriate answers for the questions.
This is one of the unanswered questions that I want to explore. I believe that this is certainly one of the deeper questions about technology. Why do I say so? Without evolution technologies seem to be born independently and improve independently. Each must come from some unexplained mental process, some form of creativity or thinking outside the box that brings it into existence and separately develops it. With evolution, new technologies would be birthed in some precise way from previous ones, albeit with considerable mid-wifing, and develop though some understood process of adaptation. In other words, if we could understand evolution, we could understand the most precious of processes: innovation. But, let me define evolution before I proceed further. The word evolution has two general meanings. One is the gradual development of something as with the evolution of ballet or the English Madrigal. The other is the process by which all objects of some class are related by ties of common descent from the collection of earlier objects. The latter is what I mean by evolution.

I. In 1867, S. Colum Gilfillan, a sociologist traced the evolution of ships from the dugout canoe to the modern steamship of the day.
II. Many theories propose the existence of a technology in many forms. From these variations, some perform better and are selected for further use and development.
III. Till date the people who have thought hardest about the general questions of technology have only been social scientists. They have viewed technology from the outside as stand-alone objects without studying earlier technologies.
IV. Some technologies, e.g., the laser, the jet engine, the radar, the quick sort algorithm and locomotive just appear, or atleast they seem to just appear unlike novel biological species which are versions of earlier objects.
V. Radar descends from radio but you can vary 1930s radio circuits as radically you like but you will never get radar. Radar requires a different principle.
