Directions (Q. 36-40) : Read the following passage carefully and answer the questions given below it.

Journalism combines writing with news gathering and interpretation. While the journalist’s work obviously varies from newspaper to newspaper and from magazine to magazine, all journalists are as much research workers, as they are writers. They cannot write their news or feature stories, unless they locate it and research them first. They must be able to read the in-between lines of the main source-news and interpret that. A great many stories hunt the journalist, who rejects most of them. he carefully sorts and sifts those, taking only a relatively very small proportion of news, may be, coming from an unexpected source. A successful journalist may gather news to the tune of 100 percent but he can use them for his profession only 3-5 percent. He must be able to see or forecast to himself, the news of tomorrow or the day after, from the news of tomorrow or the day after, from the news of today; because newspapers want advance news or advance warning to give a good, exclusive and exhaustive coverage to anything of interest. But a real ‘scoop’ is a very rare event. And bogus scoops also bring disrepute to the newspaper.

36. According to the passage, a journalist’s work includes

(a)  writing

(b)  news gathering

(c)  sorting out the news

(d)  All of the above

Answer: (d)

37. What, according to the passage, is the common characteristic of all journalists?

(a)  They all write for the newspapers

(b)  They all have to first probe into the news they gather

(c)  They all make an adventure to find a worthy news

(d)  They all can forecast future news

Answer: (b)

38. What is most important for a journalist?

(a)  He must be able to interpret the news correctly

(b)  He must know how to sort out the news

(c)  He must be able to write effectively

(d)  He must know how to gather the right news

Answer: (a)

39. What does the passage say about successful journalists?

(a)  They reject a major portion of the gathered news

(b)  They can use a relatively small portion of the news

(c)  Their news come from unexpected sources

(d)  They present advance news

Answer: (b)

40. What is the basic requisite for exclusive and exhaustive coverage of newspaper?

(a)  Forecast of tomorrow’s news from today’s news

(b)  Collecting the news of a ‘real scoop’

(c)  Selection of a small portion of the gathered news

(d)  Effective style of writing
