निर्देश: गद्यांश को पढ़कर निम्नलिखित प्रश्न में सबसे उचित विकल्प को चुनिए।
प्राचीन भारत में शिक्षा, ज्ञान प्राप्ति का सबसे बड़ा स्रोत माना जाता था। व्यक्ति के जीवन को सन्तुलित और श्रेष्ठ बनाने तथा एक नई दिशा प्रदान करने में शिक्षा का महत्त्वपूर्ण योगदान था। सामाजिक बुराइयों को उसकी जड़ों से निर्मूल करने और त्रुटिपूर्ण जीवन में सुधार करने के लिए शिक्षा की नितान्त आवश्यकता थी। यह एक ऐसी व्यवस्था थी, जिसके द्वारा सम्पूर्ण जीवन ही परिवर्तित किया जा सकता था। व्यक्ति को अपने व्यक्तित्व का विकास करने, वास्तविक ज्ञान को प्राप्त करने और अपनी समस्याओं को दूर करने के लिए शिक्षा पर निर्भर होना पड़ता था। आधुनिक युग की भाँति प्राचीन भारत में भी मनुष्य के चरित्र का उत्थान शिक्षा से ही सम्भव था। सामाजिक उत्तरदायित्वों को निष्ठापूर्वक वहन करना प्रत्येक मानव का परम उद्देश्य माना जाता है। इसके लिए भी शिक्षित होना नितान्त अनिवार्य है। जीवन की वास्तविकता को समझने में शिक्षा का उल्लेखनीय योगदान रहता है। भारतीय मनीषियों ने इस ओर अपना ध्यान केन्द्रित करके शिक्षा को समाज की आधारशिला के रूप में स्वीकार किया। विद्या का स्थान किसी भी वस्तु से बहुत ऊँचा बताया गया। प्रखर बुद्धि एवं सही विवेक के लिए शिक्षा की उपयोगिता को स्वीकार किया गया। यह माना गया कि शिक्षा ही मनुष्य की व्यावहारिक कर्तव्यों का पाठ पढ़ाने और सफल नागरिक बनाने में सक्षम है। इसके माध्यम से व्यक्ति का शारीरिक, मानसिक और आत्मिक अर्थात् सर्वांगीण विकास सम्भव है। शिक्षा ने ही प्राचीन संस्कृति को संरक्षण दिया और इसके प्रसार में मदद की। विद्या का आरम्भ ‘उपनयन संस्कार’ द्वारा होता था। उपनयन संस्कार के महत्त्व पर प्रकाश डालते हुए मनुस्मृति में उल्लेख मिलता है कि गर्भाधान संस्कार द्वारा तो व्यक्ति का शरीर उत्पन्न होता है पर उपनयन संस्कार द्वारा उसका आध्यात्मिक जन्म होता है। प्राचीन काल में बच्चों को शिक्षा प्राप्त करने के लिए आचार्य के पास भेजा जाता था। शतपथ ब्राह्मण के अनुसार, जो ब्रह्मचर्य ग्रहण करता है। वह लम्बी अवधि की यज्ञावधि ग्रहण करता है। छान्दोग्योपनिषद् में उल्लेख मिलता है कि आरुणि ने अपने पुत्र श्वेतकेतु को ब्रह्मचारी रूप से वेदाध्ययन के लिए गुरु के पास जाने को प्रेरित किया था। आचार्य के पास रहते हुए ब्रह्मचारी को तप और साधना का जीवन बिताते हुए विद्याध्ययन में तल्लीन रहना पड़ता था। इस अवस्था में बालक जो ज्ञानार्जन करता था उसका लाभ उसको जीवन भर  मिलता था। गुरु गृह में निवास करते हुए विद्यार्थी समाज के निकट सम्पर्क में आता था। गुरु के लिए समिधा, जल का लाना तथा गृह-कार्य करना उसका कर्त्तव्य माना जाता था। गृहस्थ धर्म की शिक्षा के साथ-साथ वह श्रम और सेवा का पाठ पढ़ता था। शिक्षा केवल सैद्धान्तिक और पुस्तकीय न होकर जीवन की वास्तविकताओं के निकट होती थी।

TS TET Paper 2 Mock Test - 5 (Science and Mathematics) - Question 10

Direction: ​Read the given passages carefully and answer the question that follows.
Everything that men do or think concerns either the satisfaction of the needs they feel or the need to escape from pain. This must be kept in mind when we seek to understand spiritual or intellectual movements and the way in which they develop, for feeling and longing are the motive forces of all human striving and productivity – however nobly these latter may display themselves to us.
What, then, are the feelings and the needs which have brought mankind to religious thought and to faith in the widest sense? A moment’s consideration shows that the most varied emotions stand at the cradle of religious thought and experience.
In primitive people, it is, first of all, fear that awakens religious ideas – fear of hunger, of wild animals, of illness, and of death. Since the understanding of causal connections is usually limited on this level of existence, the human soul forges a being, more or less like itself, on whose will and activities depend the experiences which it fears. One hopes to win the favor of this being, by deeds and sacrifices, which according to the tradition of the race are supposed to appease the being or to make him well disposed to man. I call this the religion of fear.
This religion is considerably established, though not caused, by the formation of priestly caste which claims to mediate between the people and the being they fear and so attains a position of power. Often a leader or despot will combine the function of the priesthood with its own temporal rule for the sake of greater security, or an alliance may exist between the interests of political power and the priestly caste.

Q. What motivates man’s actions or thinking?

Detailed Solution for TS TET Paper 2 Mock Test - 5 (Science and Mathematics) - Question 10

According to the line mentioned in the passage, Everything that men do or think concerns either the satisfaction of the needs they feel or the need to escape from pain.

TS TET Paper 2 Mock Test - 5 (Science and Mathematics) - Question 12

Direction: Read the passage given below and then answer the questions given below the passage. Some words may be highlighted for your attention.
The big fuss about consensus management is an issue that boils down to a lot of noise about not much. The consensus advocates are great admirers of the Japanese management style. Consensus is what Japan is famous for. Well, I know the Japanese fairly well: They still remember Douglas MacArthur with respect, and they still bow down to their Emperor. In my dealings with them, I found that they talk a lot about consensus, but there's always one guy behind the scenes who ends up making the tough decisions. It doesn't make sense to me to think that Mr. Toyoda or Mr. Morita of Sony sits around in committee meetings and says, "We've got to get everybody in this organization, from the janitor up, to agree with this move". The Japanese believe in their workers' involvement early on in the decision-making process and in feedback from employees. And they probably listen better than we do. But you can bet that when the chips are down, the yen stops at the top guy's desk. So, we're wasting time trying toDirection: Read the passage given below and then answer the questions given below the passage. Some words may be highlighted for your attention.

Business structures are microcosms of other structures. There were no corporations in the fifteenth century. But there were families. There were city governments, provinces, and armies. There was the Church. All of them had, for lack of a better word, a pecking order.
Why? Because that's the only way you can steer clear of anarchy. Otherwise, you'll have somebody come in one morning and tell you: "Yesterday I got tired of painting red convertibles, so today I switched to all baby-blues on my own". You'll never get anything done right that way.
What's to admire about consensus management anyway? By its very nature, it's slow. It can never be daring. There can never be real accountability - or flexibility. About the only plus that I've been able to figure out is that consensus management means consistency of direction and objectives. And so much consistency can become faceless, and that's a problem too. In any event, I don't think it can work in this country. The fun of business for entrepreneurs, big or small, lies in the free enterprise system, not in the greatest agreement by the greatest number.

TS TET Paper 2 Mock Test - 5 (Science and Mathematics) - Question 19

Aerobic respiration is done by _______.

Detailed Solution for TS TET Paper 2 Mock Test - 5 (Science and Mathematics) - Question 19

Mitochondria: 

  • Mitochondria are membrane-bound organelles present in all eukaryotic cells' cytoplasm.
  • Typically it is sausage-shaped or cylindrical having a diameter of 0.2-1.0µm (average 0.5µm) and length 1.0-4.1µm.
  • Each mitochondrion is a double membrane-bound structure with the outer membrane and the inner membrane dividing its lumen distinctly into two aqueous compartments, i.e. the outer compartment and the inner compartment.
  • The inner compartment is filled with a dense homogeneous substance called the matrix.
  • The outer membrane forms the continuous limiting boundary of the organelle. The inner membrane forms a number of infoldings called the cristae

Mitochondria for aerobic respiration:

  • Mitochondria are the sites of aerobic respiration.
  • They produce cellular energy in the form of ATP, hence they are called ‘power houses’ of the cell.
  • A series of chemical reactions occur in the cytoplasm as breakdown products from food digestion find their way into the cell.
  • This allows some of the energy stored up in these items to be released and integrated into ATP, the cell's universal energy source (adenosine triphosphate).
  • The remaining molecular fragments from this phase then reach the mitochondria, where they are converted to carbon dioxide and water through a complex sequence of steps.
  • The energy that has been trapped in these fragments is converted into more ATP.
  • The cell can then use the ATP molecules generated in this way to provide the energy it requires to work.
  • To function, ATP is made up of ADP + P + energy.
  • The overall chemical reaction that occurs when glucose is broken down is:

C6H12O6 +  6O → 6CO2 + 6H2O +  ATP (energy)

Why is it easier to carry a bag with large and broad straps?

Detailed Solution for TS TET Paper 2 Mock Test - 5 (Science and Mathematics) - Question 30
  • The weight of a bag is the force with which it is pulled towards the earth.
  • The shoulder carries a bag that exerts a force that is equal to its weight.
  • So, using a large and wide strap of bags ensures that the same weight (Force) is transferred to the shoulder through the large area of the strap.
  • For the same force, pressure ∝ 1 / area. Hence, as the area increases the pressure produced is less.
  • Therefore, since the broad and larger straps of the bag have greater area, the pressure on the shoulder becomes less, making it easier to carry the bag.

Thus, from the above discussion, the correct answer is the pressure exerted by the bag decreases.
