Read the following passage and answer
question numbers from 13 to 18 :
Often, as I (Nehru) wandered from meeting to
meeting, I spoke to my audience of this Indiaof ours, of Hindustan and of Bharata, the oldSanskrit name derived from the mythicalfounder of the race.
Sometimes as I reached a gathering, agreat roar of welcome would greet me : BharatMata Ki Jai – ‘Victory to Mother India’. I wouldask them unexpectedly what they meant by thatcry, who was this Bharat Mata, Mother India,whose victory they wanted ? My question wouldamuse them and surprise them, and then, notknowing exactly what to answer they wouldlook at each other and at me. I persisted in myquestioning. At last a vigorous Jat, wedded tothe soil from immemorial generations, wouldsay that it was the dharti, the good earth of India,that they meant. What earth ? Their particularvillage patch, or all the patches in the districtor province, or in the whole of India ? And soquestion and answer went on, till they wouldask me impatiently to tell them all about it. Iwould endeavour to do so and explain that Indiawas all this that they had thought, but it wasmuch more. The mountains and the rivers ofIndia, and the forests and the broad fields,which gave us food, were all dear to us, butwhat counted ultimately were the people ofIndia, people like them and me, who werespread out all over this vast land. Bharat Mata,Mother India, was essentially these millions ofpeople, and victory to her meant victory to thesepeople. You are parts of this Bharat Mata, I toldthem, you are in a manner yourselves, BharathMata and as this idea slowly soaked into theirbrains, their eyes would light up as if they had
made a great discovery.
