OTET Paper 2 Mock Test - 7 (Science and Mathematics) - Question 5

किसी उत्पाद का इस्तेमाल करके उपभोक्ता भी बाजार में भागीदार बन जाता है। यदि उपभोक्ता नही होंगे तो किसी भी कंपनी का अस्तित्व नही होगा। जहाँ तक उपभोक्ता के अधिकार का सवाल है तो उपभोक्ता की स्थिति दयनीय ही कही जायेगी। इसको समझने के लिए आप वैसे दुकानदार का उदाहरण ले सकते है जो कम वजन तौलता है या वह कम्पनी जो अपने पैक पर झूठे वादे करती है। ज्यादातर मिठाई बेचने वाले कच्चे माल में मिलावट करके लड्डू या बर्फी बनाते है। कुछ वर्षो पहले मिलावटी सरसों तेल से फैलने वाली ड्रॉप्सी नाम की बीमारी आपको याद होगी। यदि आपने कभी ट्रेन से सफर किया होगा तो आपको पता होगा कि ट्रेन में बिकने वाले खाने पीने की ज्यादातर चीजे घटिया होती है। यहाँ तक की पैंट्री में मिलने वाला खाना भी घटिया क्वालिटी का होता है। भारत में मिलावट, कालाबाजारी, जमाखोरी, कम वजन आदि की पुरानी परम्परा रही है। 1960 के दशक से भारत में उपभोक्ता आन्दोलन शुरू हुए थे। 1970 के दशक तक उपभोक्ता आन्दोलन केवल आर्टिकल लिखने और प्रदर्शनी लगाने तक ही सीमित था। लेकिन हाल के वर्षो में उपभोक्ता संगठनों की संख्या में तेजी से उछाल आया है।
विक्रेताओं और सेवा प्रदाताओं से लोगो में इतनी अधिक असंतुष्टि थी कि उपभोक्ताओं के पास अपनी आवाज उठाने के सिवा और कोई रास्ता नही बचा था। कई वर्षो के लम्बे संघर्ष के बाद सरकार को इसकी खैर लेने के लिए बाधित होना पड़ा और इसकी परिणति के रूप में 1986 में कंज्यूमर प्रोटेक्शन एक्ट (कोपरा) को लागू किया गया। एक उपभोक्ता को किसी उत्पाद के बारे में सही जानकारी पाने का अधिकार होता है। अब ऐसे कानून है जो किसी उत्पाद के पैक पर अवयवों और सुरक्षा के बारे में जानकारी देना अनिवार्य बनाते है। सही सूचना से उपभोक्ता को किसी भी उत्पाद को खरीदने के लिए उचित निर्णय लेने में मदद मिलती है। किसी भी उत्पाद के पैक पर खुदरा मूल्य लिखना भी अनिवार्य होता है। यदि कूई दुकानदार एमआरपी से अधिक चार्ज करता है तो उपभोक्ता उसकी शिकायत कर सकता है। एक उपभोक्ता को विभिन्न विकल्पों में से चुनने का अधिकार होता है। कोई भी विक्रेता केवल एक ही ब्रांड पेश नही कर सकता है। उसे अपने ग्राहक को कई विकल्प देने होगे। इस अधिकार को मोनोपोली ट्रेंड के खिलाफ बने कानूनों के जरिये लागू किया जाता है।

Q. अधिकारों के मामले में भारतीय उपभोक्ताओं की स्थिति कैसी है?

विनम्रता का यह कथन बहुत ठीक है कि विनम्रता के बिना स्वतंत्रता का कोई अर्थ नहीं। इस बात को सब लोग मानते हैं कि आत्मसंस्कार के लिए थोड़ी बहुत मानसिक स्वतंत्रता परमावश्यक है – चाहे उस स्वतंत्रता में अभिमान और नम्रता दोनों का मेल हो और चाहे वह नम्रता ही से उत्पन्न हो। यह बात तो निश्चित है कि जो मनुष्य मर्यादापूर्वक जीवन व्यतीत करना चाहता है उसके लिए वह गुण अनिवार्य है, जिससे आत्मनिर्भरता आती है और जिससे अपने पैरों के बल खड़ा होना आता है। युवा को यह सदा स्मरण रखना चाहिए कि वह बहुत कम बातें जानता है, अपने ही आदर्श से वह बहुत नीचे है और उसकी आकांक्षाएँ उसकी योग्यता से कहीं बढ़ी हुई हैं। उसे इस बात का ध्यान रखना चाहिए कि वह अपने बड़ों का सम्मान करे, छोटे और बराबर वालों से कोमलता का व्यवहार करे, ये बातें आत्म-मर्यादा के लिए आवश्यक हैं। यह सारा संसार, जो कुछ हम हैं और जो कुछ हमारा है – हमारा शरीर, हमारी आत्मा, - हमारे कर्म, हमारे भोग, हमारे घर और बाहर की दशा हमारे बहुत से अवगुण, और थोड़े गुण सब इसी बात की आवश्यकता प्रकट करते हैं कि हमें अपनी आत्मा को नम्र रखना चाहिए। नम्रता से मेरा अभिप्राय दब्बूपन से नहीं है जिसके कारण मनुष्य दूसरों का मुँह ताकता है जिससे उसका संकल्प क्षीण और उसकी प्रज्ञा मंद हो जाती है, जिसके कारण बढ़ने के समय भी पीछे रहता है और अवसर पड़ने पर झट से किसी बात का निर्णय नहीं कर सकता। मनुष्य का बेड़ा उसके अपने ही हाथ में है, उसे वह चाहे जिधर ले जाए। सच्ची आत्मा वही है जो प्रत्येक दशा में प्रत्येक स्थिति के बीच अपनी राह आप निकालती है।

OTET Paper 2 Mock Test - 7 (Science and Mathematics) - Question 10

बच्चे के विकास में मौखिक रचना क्यों उपयोगी है?

Detailed Solution for OTET Paper 2 Mock Test - 7 (Science and Mathematics) - Question 10

बच्चे के विकास में मौखिक रचना भाषा में प्रवाह प्रदान करता है, व्याकरण को सही करता है तथा आत्मविश्वास का निर्माण करता है। भाषा शिक्षण में मौखिक रचनाएँ बहुत लोकप्रिय रही हैं। विचार यह है कि शिक्षक और छात्र एक साथ काम कर रहे हैं ताकि इसे लिखने से पहले मौखिक रूप से एक कथा का निर्माण किया जा सके। पूरी कक्षा के साथ रचना के निर्माण की प्रक्रिया शिक्षक और छात्रों को तनावपूर्ण उपयोग से लेकर एकजुट तत्वों आदि तक विभिन्न प्रकार की भाषा वस्तुओं पर ध्यान केंद्रित करने की अनुमति देती है। एक बार जब बच्चा मौखिक रूप से अन्य आत्मविश्वास से संवाद करता है तो मौखिक रचना व्याकरण को बहुत प्रभावित करती है। इस तरह के अभ्यास करने के बाद उन्हें भाषा में भी निपुणता प्राप्त हो जाती है।

भाषा एक औजार है जिसका उपयोग निम्न रूप से किया जाता है:

  • जिंदगी के अनुभवों को साझा करने के लिए
  • भाषा जिंदगी से जुड़ने के लिए सहायक है  
  • भाषा जिंदगी को समझने के लिए उपयोगी है 
  • भाषा जीवन जगत को प्रस्तुत करने के लिए सहायक है 
  • जीवन संबंधी मनन और विचार शक्ति के विकास के लिए

अतः हम कह सकते है कि भाषा कठोरता से व्‍याकरणिक नियमों का अनुसरण करती है, कथन भाषा की प्रकृति के सम्‍बन्‍ध में उचित नहीं है।

  • Active participation means indulging in activity in such a way that the individual not only performs with full dedication but also takes complete responsibility for the actions.
  • A teacher in the third-grade classroom decided to give some tasks to the students after teaching them a poem. 
OTET Paper 2 Mock Test - 7 (Science and Mathematics) - Question 15

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.

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.
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.

Detailed Solution for OTET Paper 2 Mock Test - 7 (Science and Mathematics) - Question 17

The teacher is doing task-based language teaching.
The Task-Based Approach (TBA) has gained popularity in the field of language teaching since the last decade of the 20th Century. Task-based language teaching:- It is teaching where the planning and teaching depend on a task.

  • In this case, the teacher is asking to present a short presentation for a vacation. So, it is based on a particular task.
  • Task-based learning is especially conducive to group learning. Learning a language as a group is also a very important contributor to effective retention. Collaborating with others and becoming confident with the language within a group is a key step in acquiring that language.
  • Task-based learning uses a lesson structure that incorporates different activities to solve a task. The task can span the length of an entire lesson or, if it’s project-based learning, it can take up several lessons to complete.

Thus, it is concluded that a teacher asks students she plans a vacation they’re going to take together as a group, and then after coming from vacation they will do a short presentation about it to the class, or submit a written assignment or video explaining it. The teacher is doing Task-based language teaching.

Detailed Solution for OTET Paper 2 Mock Test - 7 (Science and Mathematics) - Question 20

The teaching of English must be done in a way so that reduces errors and compels students to use English in their daily life and gives them confidence and satisfaction while using the language. The main purpose of teaching a language in education is to make a child proficient in that specific language.

  • Fluency in English means that the child can use the basic skills of language which are listening, speaking, reading, and writing.  
  • One who can perform these basic skills properly and collectively with full accuracy and speed is said to be fluent in English.
  • Fluency is related to the one specific domain in a language whereas proficiency means that a person can collectively use all the language skills together and can smoothly use them in their life.
  • A person who is proficient is said to be fluent in a specific language. But it is not necessary that a person who is fluent will always be proficient in that language.
  • A fluent person can use a skill smoothly at a time but a proficient person can use all the skills together at a time. 
  • The teacher must create opportunities to use the language for communication among learners to develop their fluency and proficiency in English.
  • This can be done by conducting several language-based activities such as discussions, drama, dialogues, conversations, debates, questionnaires, etc.

Therefore, it is concluded that when a child has acquired all the language skills then he is said to be proficient in that language.

Find the remainder when 8317+5217+8417+5317 is divided by 68.

Detailed Solution for OTET Paper 2 Mock Test - 7 (Science and Mathematics) - Question 26

Given:
8317 + 5217 + 8417 + 5317 is divided by 68
Concept used:
an + bn is divided by (a + b) when n is an odd number.
Calculation:
8317 + 5217 + 8417 + 5317
= (8317 + 5317) + (5217 + 8417)
Here, n = 17 is an odd number
Also, 83 + 53 = 52 + 84 = 136
The whole number is divisible by 136
So, the whole number is divisible by 68  [∵ 136 = 68 × 2]
Since the whole number is divisible by 68 the remainder must be 0
∴ The remainder is 0.

OTET Paper 2 Mock Test - 7 (Science and Mathematics) - Question 27

If 4x2 + 12xy – 8x + 9y2 – 12y = (ax + by) (ax + by – 4), then the value of a2 + b2 is

Detailed Solution for OTET Paper 2 Mock Test - 7 (Science and Mathematics) - Question 27

4x2 + 12xy – 8x + 9y2 – 12y
= (2x)2 + 12xy – 8x + (3y)2 – 12y
= (2x)2 + 12xy + (3y)2 - 8x - 12y
= (2x + 3y)2 - 4(2x + 3y)
= (2x + 3y)(2x + 3y - 4) = (ax + by)(ax + by - 4)
