A. 1 Read the passage given below and answer the questions that follow it:Engineers seldom get the praise they deserve from the ordinary netán.Interesting stories for young people have been written about famousinventors, doctors, travellers and other notable people, but the names offamous engineers remain largely unknown except to students of technicalInstitutions. This is not because engineers have contributed less than thoseothers to the progress of mankind, but because the details of theirachievements are usually too technical to be understood by the ordinaryreader. A layman without some knowledge of technical terms, as well as someknowledge of physics and mathematics, would find it difficult to fullyappreciate the greatness of I.K. Brunel and the other famous engineers whoworked on the problems of the early railways - deciding on points like the basicboiler, the best type of rails, whether the sleepers should be of wood or metaland whether the rails should be 7 it apart (broad gauge) or 4 ft. 8 % in(standard gauge) or even less (narrow gauge). The result is that apart from oneor two people like James Watt and George Stephenson, who have been giventhe credit accorded to inventors, very little popular appreciation has gone toother engineers. Even less known or rather, less wondered at, are other featsof engineering such as the building of tunnels and bridges. We all know abouttunnels especially the railway tunnels which carry railways through hills, butnot many people realise that it is a very difficult task, demanding a lot ofthinking on the part of the engineers, to construct a tunnel in exactly the rightplace, going in exactly the right direction, and so strong that there is no dangerof tons of earth falling and burying the people using the tunnel. Bridges, whichwe use practically every day, are better known - so well known that it hardlyever occurs to us that each bridge is a challenge to the skill of the engineer,who has to study the nature of the site and the soil, the volume of water in theriver to be bridged, etc., before he finally sits down at his desk to work outtechnical problems such as the type of bridgeto be used, the precise design and weight of the arches and pillars, and thekind and amount of steel reinforcement to be used in the concrete, to name afew(A) Fill in the blanks with suitable words from the passage.i) Railway tunnels carry railwayshills.(i) The names of famous engineers remain largelyand(iii) Two well-known engineers associated with railways areand(iv) Feats of engineering include the building of(v) Broad gauge rails areapart(B) On the basis of the given passage, answer the following questions in brief(30 - 40 words each), in your own words as far as possible:(1) Why do ordinary people not appreciate the contribution of engineers?(it) What did the engineers have to keep in mind while working on theproblems of the early railways?(ill) What special difficulties are mentioned in connection with the making oftunnels?(iv) What sorts of facts does the bridge-builder need to know before he canbuild the bridge?(v) What is the main idea in the passage above?​
