    अब्दुल कलाम का जन्म 15 अक्टूबर 1931 धनुषकोडी गाँव (रामेश्वरम, तामिलनाडु ) में एक मध्यमवर्ग मुस्लिम परिवार में हुआ था। इनके पिता जैनुलाब्दीन न तो ज़्यादा पढ़ेलिखे थे, न ही पैसे वाले थे। इनके पिता मछुआरों को नाव किराये पर दिया करते थे। अब्दुल कलाम संयुक्त परिवार में रहते थे। परिवार की सदस्य संख्या का अनुमान इस बात से लगाया जा सकता है कि यह स्वयं पाँच भाई एवं पाँच बहन थे और घर में तीन परिवार रहा करते थे। अब्दुल कलाम के जीवन पर इनके पिता का बहुत प्रभाव रहा। वे भले ही पढ़े-लिखे नहीं थे, लेकिन उनकी लगन और उनके दिए संस्कार अब्दुल कलाम के बहुत काम आए। पाँच वर्ष की अवस्था में रामेश्वरम की पंचायत के प्राथमिक विद्यालय में उनका दीक्षासंस्कार हुआ था। उनके शिक्षक इयादुराई सोलोमन ने उनसे कहा था कि जीवन मे सफलता तथा अनुकूल परिणाम प्राप्त करने के लिए तीव्र इच्छा, आस्था, अपेक्षा इन तीन शक्तियो को भलीभाँति समझ लेना और उन पर प्रभुत्व स्थापित करना चाहिए। पांचवी कक्षा में पढ़ते समय उनके अध्यापक उन्हें पक्षी के उड़ने के तरीके की जानकारी दे रहे थे, लेकिन जब छात्रों को समझ नही आया तो अध्यापक उनको समुद्र तट ले गए जहाँ उड़ते हुए पक्षियों को दिखाकर अच्छे से समझाया, इन्ही पक्षियों को देखकर कलाम ने तय कर लिया कि उनको भविष्य में विमान विज्ञान में ही जाना है। कलाम के गणित के अध्यापक सुबह ट्यूशन लेते थे इसलिए वह सुबह 4 बजे गणित की ट्यूशन पढ़ने जाते थे. अब्दुल कलाम ने अपनी आरंभिक शिक्षा जारी रखने के लिए अख़बार वितरित करने का कार्य भी किया था। कलाम ने 1950 में मद्रास इंस्टीट्यूट ऑफ टेक्नोलजी से अंतरिक्ष विज्ञान में स्नातक की उपाधि प्राप्त की है। स्नातक होने के बाद उन्होंने हावरक्राफ्ट परियोजना पर काम करने के लिये भारतीय रक्षा अनुसंधान एवं विकास संस्थान में प्रवेश किया। 1962 में वे भारतीय अंतरिक्ष अनुसंधान संगठन में आए जहाँ उन्होंने सफलतापूर्वक कई उपग्रह प्रक्षेपण परियोजनाओं में अपनी भूमिका निभाई। परियोजना निदेशक के रूप में भारत के पहले स्वदेशी उपग्रह प्रक्षेपण यान एसएलवी 3 के निर्माण में महत्त्वपूर्ण भूमिका निभाई जिससे जुलाई 1982 में रोहिणी उपग्रह सफलतापूर्वक अंतरिक्ष में प्रक्षेपित किया गया था।

    Directions: In the following question, select the most appropriate option to fill in the blank from the given alternatives.

    Junk food is low in _________ components like fibre and antioxidants.
    Solution
    1. 'Protective' means 'capable of giving protection'.
    2. 'Protected' means 'kept safe or defended from danger or injury or loss,' hence fails to fit in the context.
    3. 'Protect,' the verb, is inappropriate as per the sentence.
    4. 'Protecting' refers to 'a shielding (or designed to shield) against harm or discomfort,' which is unfit for the sentence.
      The only adjective that can be used here for 'components,' to make the sentence meaningful, is 'protective.'

    Solution
    'Cannot' is the correct modal to be used here for expressing incapacity. Since the sentence is in the present tense, 'could not' is incorrect.
    Option 4 is incorrect as 'be' shall be followed by the third form of verb. Hence, it can't be correct with 'give.'

    As my train was not due to leave for another hour, I had plenty of time to spare. After buying some magazines to read on the journey, I made my way to the luggage office to collect the heavy suitcase I had left there three days before. There were only a few people waiting and I took out my wallet to find the receipt for my case. The receipt did not seem to be where I had left it. I emptied the contents of the wallet and the railway tickets, money, scraps of paper and photographs tumbled out of it, but no matter how hard I searched, the receipt was nowhere to be found.

    I explained the situation sorrowfully to the assistant. The man looked at me suspiciously as if to say he had heard this type of story many times and asked me to describe the case. I told him that it was an old, brown looking object no different from the many suitcases I could see on the shelves. The assistant then gave me a form and told me to make a list of the contents of the case. If they were correct, he said, I could take the case away. I tried to remember all the articles I had hurriedly packed and wrote them down.

    After I had done this, I went to look among the shelves. There were hundreds of cases there and for one dreadful moment, it occurred to me that if someone had picked the receipt up, he could easily have claimed the case already. Fortunately this had not happened, for after a time, I found the case lying on its side high up in the corner. After examining the articles inside, the assistant gave me the case.

    I took out my wallet to pay him. I pulled out a ten shilling note and out slipped my 'lost' receipt with it! I could not help blushing. The assistant nodded his head knowingly, as if to say that he had often seen this happen too!

    There weren't ____________ people waiting at the luggage office.
    Solution
    Correct Answer: very many

    'Many' is used for countable nouns. The blank qualifies the word 'people'. So, 'very many' is the right choice.
    The other words are not suitable here. 'Much' is used with uncountable nouns, 'lots of' is preferably used in a positive way.

    I explained the situation sorrowfully to the assistant. The man looked at me suspiciously as if to say he had heard this type of story many times and asked me to describe the case. I told him that it was an old, brown looking object no different from the many suitcases I could see on the shelves. The assistant then gave me a form and told me to make a list of the contents of the case. If they were correct, he said, I could take the case away. I tried to remember all the articles I had hurriedly packed and wrote them down.

    After I had done this, I went to look among the shelves. There were hundreds of cases there and for one dreadful moment, it occurred to me that if someone had picked the receipt up, he could easily have claimed the case already. Fortunately this had not happened, for after a time, I found the case lying on its side high up in the corner. After examining the articles inside, the assistant gave me the case.

    I took out my wallet to pay him. I pulled out a ten shilling note and out slipped my 'lost' receipt with it! I could not help blushing. The assistant nodded his head knowingly, as if to say that he had often seen this happen too!

    What is multiple cropping?
    Solution
    In agriculture, multiple cropping is the practice of growing two or more crops in the same piece of land in same growing season instead of one crop. It is a form of polyculture. It can take the form of double-cropping, in which a second crop is planted after the first has been harvested, or relay cropping, in which the second crop is started amidst the first crop before it has been harvested. Hence, option (2) is correct.
