If Shyam is handicapped, he has trouble adjusting with the rest of the children in the class, then he tries to establish the adjustment in the class by bringing first place in the class. Which defense device is being adopted by Shyam?
Detailed Solution for REET Level 2 Mock Test - 10 (Science and Mathematics) - Question 4

Defense mechanisms are learned and designed to tackle self-devaluation, anxiety, and hurt and operate automatically at habitual levels. They typically involve measures of self-deception and distortion. Defense mechanisms are usually exercised in combination instead of singly and quite often they are combined with task-oriented behavior. To a great extent, they are necessary to soften failure, alleviate anxiety and hurt, and protect feelings of significance adequacy, and worth. Normally, they are adjustive reactions but sometimes they seriously interfere with the effective resolution of stress. Defense mechanisms may feature in a negative or a positive form.

Which of the following is not a trait (ability) of a creative child?
Detailed Solution for REET Level 2 Mock Test - 10 (Science and Mathematics) - Question 6

Creativity is a cognitive ability to produce something original by offering a fresh perspective. It is the ability possessed by people who are creative, persistent, and imaginative.
Creativity is related to divergent thinking which refers to a way of solving problems by more than one approach. It is goal-directed thinking which is unusual, novel, and useful and includes brainstorming and out-of-the-box thinking in it

  • Creative children are those who show high-performance capability in several areas such as artistic and creative work, leadership quality, keen power of observation, etc.
  • These children have divergent thinking and are very curious in nature that's why sometimes the classroom seems monotonous to them because they grab things fastly than of their age-peers.

Trait (ability) of a creative child:

  • Elaboration
  • Abstracting ability
  • Fluency & Flexibility
  • Originality & Novelty
  • Sensitivity of problems

Characteristics of Creative Children:

  • Perceive relation between impossible things.
  • Curious, extrovert, and ambitious in nature.
  • Think quickly and solve problems in a novel way.
  • Convert imaginative and original ideas into reality.
  • Use divergent and out-of-the-box thinking in different situations.
  • Try new things and risk failure in executing innovative ideas.

Accuracy refers to the ability to do anything without making any mistakes. it is the state of being precise and accurate. It is not necessary that every time the creative child will be accurate as it is natural for them also to make mistakes.
So, it could be concluded that 'Accuracy' is not a trait (ability) of a creative child.

निर्देश: गद्यांश को पढ़िए और नीचे दिए गए प्रश्न का उत्तर दीजिए।
प्रेम आत्मा का भोजन है, प्रेम परमात्मा की ऊर्जा है जिससे प्रकृति का सारा सृजन होता है। आध्यात्म जगत में प्रेम से ज्यादा महत्त्वपूर्ण कोई शब्द नहीं है। यही वह रसायन है जो आत्मा को परमात्मा से जोड़ देता है। जब आप प्रेम में उतर जाते हो तो प्रेम का प्रत्युत्तर अपने आप आना शुरू हो जाता है। आप सद्गुरु की आँखों में प्रेम से झांकते हो तो सद्गुरु की प्रेम ऊर्जा आपको ऐसे लपेटने लगती है कि आप मंत्रमुग्ध होकर उसी के हो जाते हो। सद्गुरु को पकड़ो। पकड़ने का अर्थ है – सबसे पहले वहां साष्टांग हो जाओ, झुक जाओ यानि अहंकार के विसर्जन का, प्रेम का, प्रीती का अभ्यास सद्गुरु के चरणों से शुरू करो।  एक बात और है – प्रेम करना नहीं होता, प्रेम तो स्वयं हो जाता है। लेकिन इस प्रेम के होने में बुद्धि सबसे बड़ी बाधा बन जाती है। बुद्धि सोच विचार करती है। तर्क वितर्क करती है, वह खुले ह्रदय से अनुभव नहीं करने देती है।  बुद्धि बंधन है, उसी से मुक्त होना है और उपलब्ध रहना है उन प्रेम के क्षणों में। प्रेम की भूल-भुलैया का जरा अनुभव तो करो, लेकिन बुद्धि से नहीं, ह्रदय खोलकर प्रेम का दिया बनो। प्रेम का अर्थ होता है – दूसरों को इतना अपना बना लेना कि कुछ छिपाने को बचे ही नहीं। एक कसौटी दे रहा हूँ आपको, जब आपको लगने लगे कि उससे छिपाने को कुछ भी नहीं रहा तब समझना कि आपको सच्चे अर्थों में प्रेम हो गया है। सद्गुरु ही एकमात्र व्यक्तित्व है जो निःस्वार्थ प्रेम करता है।  उसे आपसे कुछ पाना नहीं है। उसे तो अपना सब कुछ आपके ऊपर लुटाना है। उसके प्रति प्रेम करने में कठिनाई का अनुभव नहीं होना चाहिए। वह तो खूँटी है। उसी खूँटी से अभ्यास करो। ऋषियों ने कहा है, प्रकृति से प्रेम करो।  फिर धीरे-धीरे मनुष्य पर आओ। मनुष्य से आकर आप सीधे परमात्मा तक पहुंचोगे। ऋषियों ने पहाड़ों को पूजा, नदियों को पूजा, वृक्षों को पूजा, चाँद-तारों को पूजा। किसलिए? उन्होंने सन्देश दिया कि सारी पृथ्वी से प्रेम करो। विराट अस्तित्व ही परमात्मा है। सबके प्रति प्रेम से इतना भर जाओ कि आपकी लय, आपका संगीत, आपका छंद उस परमात्मा से जुड़ जाये।  जो-जो शरीर में है वह सब ब्रह्मांड में है। सारे धर्म इसी बात का विज्ञान हैं और कुछ नहीं। प्रेम की एक ही साधना है, एक ही संकल्पना है जिसके साध लेने पर आध्यात्म की सारी साधनाएँ प्रकट हो जायेंगी।

Q. परमात्मा क्या है?
Detailed Solution for REET Level 2 Mock Test - 10 (Science and Mathematics) - Question 9

गद्यांश के अनुसार, "विराट अस्तित्व ही परमात्मा है। सबके प्रति प्रेम से इतना भर जाओ कि आपकी लय, आपका संगीत, आपका छंद उस परमात्मा से जुड़ जाये।"
इसलिए, यह निष्कर्ष निकाला जा सकता है कि विराट अस्तित्व परमात्मा है।

कछुआ, मगर और शार्क के समान, गंगा की डॉलफिन एक अत्यंत प्राचीन जलचर है। औपचारिक रूप से इसकी खोज सन् 1801 में हुई थी। पहले यह दक्षिण एशिया, विशेष रूप से भारतीय उपमहाद्वीप में बहुत बड़े क्षेत्र में फैली हुई थी तथा बड़ी संख्या में पाई जाती थी। यह भारत, बांग्लादेश तथा नेपाल में कई नदियों में मिलती थी, किंतु वर्तमान समय में केवल गंगा, ब्रह्मपुत्र, मेघना और कर्णफुली में शेष बची। है। कभी-कभी यह चम्बल, घाघरा और सप्तकोशी नदियों में भी देखने को मिल जाती है।
गंगा की डॉलफिन भारत के सात राज्यों की चुनी हुई नदियों में मिलती है। ये राज्य हैं- असम, उत्तर प्रदेश, मध्य प्रदेश, बिहार, राजस्थान, झारखंड और पश्चिम बंगाल। यहाँ इसे गंगा, चंबल, घाघरा, गंडक, सोन, कोसी, ब्रह्मपुत्र आदि नदियों तथा इनकी सहायक नदियों में देखा जा सकता है। केवल ताज़े पानी की नदियों में रहने वाली यह डॉलफिन अकेली अथवा बहुत छोटे-छोटे झुंडों में रहती है। इसके झुंड में सदस्यों की संख्या प्रायः तीन से अधिक नहीं होती। सामान्यतया बच्चेवाली मादा डॉलफिन, अपने बच्चे के साथ विचरण करती हुई दिख जाती है

कौन-सा उपागम शिक्षार्थियों में संप्रेषणात्मक दक्षता उत्पन्न करता है?
Detailed Solution for REET Level 2 Mock Test - 10 (Science and Mathematics) - Question 13

संप्रेषणीय उपागम विशुद्ध रूप से भाषाई ज्ञान के विपरीत शिक्षार्थियों के बीच 'संवादात्मक क्षमता' (भाषा को प्रभावी व्यावहारिक उपयोग में लाने की क्षमता) विकसित करने का प्रयास करता है।
संप्रेषणीय दृष्टिकोण इस विचार पर आधारित है कि किसी भाषा को सफलतापूर्वक सीखना वास्तविक अर्थ को संप्रेषित करने के माध्यम से आता है।
जब शिक्षार्थी वास्तविक संचार में शामिल होते हैं, तो भाषा अधिग्रहण के लिए उनकी प्राकृतिक रणनीतियों का उपयोग किया जाएगा, और यह उन्हें भाषा सीखने और उपयोग करने की अनुमति देगा।
संप्रेषणीय उपागम भाषा शिक्षण की एक विधि है जो शिक्षार्थियों को वास्तविक संप्रेषण में प्रभावशाली ढंग से शामिल करता है।
यह एक शिक्षार्थी-केंद्रित उपागम है जो शिक्षार्थी को प्राकृतिक वातावरण में भाषा सीखने में मदद करता है।
यह लेखन कौशल और संचार के व्याकरण संबंधी पहलुओं पर जोर देने के बजाय सीखने के लिए वास्तविक संचार के महत्व पर प्रकाश डालता है।
भाषाई क्षमता से तात्पर्य किसी व्यक्ति की लक्ष्य भाषा का ज्ञान रखने और उसी के उपयोग को समझने की क्षमता से है।
इसलिए, हम यह निष्कर्ष निकाल सकते हैं कि संप्रेषणात्मक उपगम शिक्षार्थियों में संप्रेषणात्मक दक्षता उत्पन्न करता है।
अतः विकल्प (C) सही  है।

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.

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.

Q. What is the central idea behind the passage?
Detailed Solution for REET Level 2 Mock Test - 10 (Science and Mathematics) - Question 17

The author tries to convey that consensus management is impractical, especially in a free enterprise system. Even the Japanese pretend to follow it but they actually don't. No one can actually follow it in order to become a superpower.
"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 to emulate something I don't think really exists."
A general agreement regarding something sounds great, but it is impossible to practise it as it would result in anarchy or a state of disorder. 
So, it can be concluded that consensus management exists more in theory than practice. The phrase 'in theory' is used to say that something seems to be true or possible as an idea but may not actually be true or possible.
Other options are rejected because Option (A) is an integral message of the passage but cannot be stated as the central idea of the passage. Option (B) and (D) are factually incorrect.

Friction: Friction is an opposing force that comes into play when the body is actually moving (slide or roll) or even tries to move over the surface of another body.

The presence of irregularities between the two surfaces in contact causes friction. 
Cause of Friction:
Friction is a evil because it cause of loss of energy and wear and tear of surfaces.

  • Soles of shoes wear out
  • We feel heat when we rub our hands.
  • Lighting a matchstick
  • Working of an eraser
  • Coming down a Kid’s slide
  • Holding onto objects

Detailed Solution for REET Level 2 Mock Test - 10 (Science and Mathematics) - Question 25

Ecosystem: 

  • All organisms such as plants, animals, microorganisms, and human beings as well as the physical surroundings interact with each other and maintain a balance in nature.
  • All the interacting organisms in an area together with the non-living constituents of the environment form an ecosystem.

Autotrophs are organisms that can produce their own food, using materials from inorganic sources by using basic energy sources such as sunlight.

  • Plants are the main example of autotrophs, using photosynthesis.
  • Some autotrophs, such as green plants and algae, are phototrophs, they convert electromagnetic energy from sunlight into chemical energy in the form of glucose. So, Spinach, Tomato, Banana are also examples of autotrophs.

Mode of Nutrition:

Autotropic: The mode of nutrition in which organisms make food themselves from simple substances is called autotrophic (auto = self; trophos = nourishment) nutrition. Therefore, plants are called autotrophs. Ex- Plants, Tress, algae, etc.
Heterotrophic: Animals and most other organisms take in ready-made food prepared by the plants. They are called heterotrophs (heteros = other).

  • Holozoic: Animals who take in solid food and breakdown it inside their body like animals, amoeba, etc. comes under the holozoic mode of nutrition.
  • Parasitic: Parasites live inside or outside the other organism (host) and get their nutrition from the host. Ex - Ticks, Cuscuta (dodder), mosquito, etc.
  • Saprophytic: In this mode of nutrition the organisms take in nutrients in solution form from dead and decaying matter is called saprotrophic nutrition. Ex- Fungi grows on pickles, leather, etc.

Hence, Carbon dioxide and water, sunlight, chlorophyll all are correct.

The project method has been developed based on certain principles. Which of the following is incorrect in terms of its principles?
Detailed Solution for REET Level 2 Mock Test - 10 (Science and Mathematics) - Question 29

The project method attempts to allow the student to solve problems with as little teacher direction as possible. The teacher is seen more as a facilitator than being the one to deliver knowledge and information.
Students in a project method environment should be allowed to explore and experience their environment through their senses and, in a sense, direct their own learning by their individual interests. Very little is taught from textbooks and the emphasis is on experiential learning, rather than rote and memorisation. A project method classroom focuses on democracy and collaboration to solve 'purposeful' problems.

What is immaterial for an fuse wire?
Detailed Solution for REET Level 2 Mock Test - 10 (Science and Mathematics) - Question 30
  • Its specific resistance: A material with higher resistance will heat up more quickly, leading to faster melting of the fuse in case of overcurrent.
  • Its radius: A thinner wire (smaller radius) will heat up and melt faster than a thicker one for the same material and current, making the fuse more sensitive.
  • Its length: A longer wire has more resistance than a shorter one (for the same material and cross-sectional area), and therefore it will heat up more quickly.
  • Current flowing through it: The fuse is designed to melt (or "blow") when a certain current threshold is exceeded. This is the fundamental operating principle of a fuse.
  • However, if we had to choose the least important factor from the ones you listed, it would be the length of the fuse wire.
  • In practical applications, fuse wires are usually very short, so while the length does technically affect the resistance (and therefore the heating), its effect is likely to be much smaller compared to the other factors.
  • Still, this doesn't mean length is completely immaterial; it's just potentially less critical in most cases.
