UP TET Paper 2 Mock Test - 4 (Science and Mathematics) - Question 12

भाषा के बारे में सत्य कथन का चयन करो-

Detailed Solution for UP TET Paper 2 Mock Test - 4 (Science and Mathematics) - Question 12

सामान्यतया यह माना जाता है कि भाषा अभिव्यक्ति और संप्रेषण का माध्यम है, जिसकी सहायता से लोग एक-दूसरे तक अपनी बात पहुँचाते हैं। भाषा को मात्र संप्रेषण का माध्यम मानना, भाषा के प्रति संकुचित दृष्टिकोण है। वास्तव में भाषा की भूमिका इससे कहीं अधिक है।

UP TET Paper 2 Mock Test - 4 (Science and Mathematics) - Question 13

निर्देश: निम्नलिखित गद्यांश को ध्यानपूर्वक पढ़कर पूछे गए बहुविकल्पीय प्रश्न का उत्तर दीजिए।
चुनाव पूर्व सर्वेक्षण एवं एक्जिट पोल का लोकतन्त्र में क्या महत्त्व है? यह प्रश्न विचारणीय है। लोकतन्त्र रूपी वृक्ष जनता द्वारा रोपा और सींचा जाता है, इसके पल्लवन एवं पुष्पन में मीडिया की विशेष भूमिका होती है। भारत एक लोकतान्त्रिक राष्ट्र है।लोकतान्त्रिक राष्ट्र में नागरिकों को विशिष्ट अधिकार और स्वतन्त्रताएँ प्राप्त होती हैं। भारतीय संविधान ने भी अनुच्छेद 19 (i) के अन्तर्गत नागरिकों को अभिव्यक्ति की स्वतन्त्रता प्रदान की है, लेकिन जनता के व्यापक हित पर प्रतिकूल प्रभाव डालने वाली स्वतन्त्रता बाधित भी की जानी चाहिए।
भारत जैसे अल्पशिक्षित देश में इस प्रकार के सर्वेक्षण अनुचित हैं। देश की आम जनता पर मीडिया द्वारा किए जाने वाले चुनाव पूर्व सर्वेक्षण और चुनाव के तुरन्त पश्चात् किए जाने वाले एक्जिट पोल का भ्रामक प्रभाव पड़ता है। वह विजयी होती पार्टी की ओर झुक जाती है। आज भी सामान्य लोगों के बीच ये आम धारणा है कि हम अपना वोट खराब नहीं करेंगे, जीतने वाले प्रत्याशी को ही वोट देंगे।
वर्तमान में बाजारवाद अपने उत्कर्ष पर है और मीडिया इसके दुष्प्रभाव से अनछुआ नहीं है। यह कहना अतिशयोक्ति न होगी कि आज मीडिया भी अधिकाधिक संख्या में प्रसार और धन पाने को बुभुक्षित है। मीडिया सत्ताधारी और मजबूत राजनीतिक दलों के प्रभाव में भी रहता है। ये दल धन के बल पर लोक रुझान को अपने पक्ष में दिखाने में सफल हो जाते हैं और सम्पूर्ण चुनाव प्रक्रिया को ही धता बता देते हैं। इस प्रकार सत्ता एवं धन इन सर्वेक्षणों को प्रभावित करते हैं। इन्हें दूध का धुला नहीं कहा जा सकता। भारत जैसे लोकतान्त्रिक राष्ट्र में जहाँ जनता निर्वाचन प्रक्रिया के माध्यम से अपना मत अभिव्यक्त करती है, वहाँ इन सर्वेक्षणों के औचित्य-अनौचित्य पर विचार किया जाना चाहिए।
न्यायालय को यदि संविधान के अनुसार चलने की बाध्यता है, तो संसद को संविधान में संशोधन करने की शक्ति प्राप्त है। वह अपने अधिकारों का प्रयोग करके कोई सार्थक प्रयास कर सकती है।

Q. 'सम्पूर्ण चुनाव प्रक्रिया को ही धता बता देते हैं।'

UP TET Paper 2 Mock Test - 4 (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.

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. Which of the following is true as per the given passage?

Detailed Solution for UP TET Paper 2 Mock Test - 4 (Science and Mathematics) - Question 15

Reading the passage we find that:
'To do something in letter and spirit' means 'to follow the rules surrounding it and their intentions completely' and nowhere in the entire passage does the author ask the Japanese to practise consensus management. Thus, Option (A) is incorrect.
The last paragraph states: 'What's to admire about consensus management anyway? By its very nature, it's slow. It can never be daring.' Thus, Option (B) is also incorrect.
Nowhere in the passage does the author talk about 'India' or about 'Japan's army'. Which shows that Option (C) and (D) are incorrect.
Thus, it is clear that the first four options are factually incorrect as they completely disregard what's been said in the passage.

UP TET Paper 2 Mock Test - 4 (Science and Mathematics) - Question 16

While testing paragraph writing the teacher should ask the students to: 

Detailed Solution for UP TET Paper 2 Mock Test - 4 (Science and Mathematics) - Question 16

Writing is a creative and expressive skill, and asking students to generate their own ideas allows them to showcase their understanding, creativity, and ability to organize their thoughts in written form.

  • Paragraph writing is the process of composing a group of related sentences that focus on a specific topic or idea, presenting coherent and organized information to convey meaning and support a central theme or argument.
  • While testing paragraph writing, it is ideal for the teacher to ask students to express their own thoughts and ideas rather than copying from a textbook or relying on memorized content.
  • It also provides an opportunity for students to develop their critical thinking skills, language proficiency, and ability to communicate effectively.
  • By encouraging students to write their own thoughts, teachers can assess their writing skills, coherence, and ability to express themselves independently.

Hence, it is clear that while testing paragraph writing the teacher should ask the students to write their own thoughts.

UP TET Paper 2 Mock Test - 4 (Science and Mathematics) - Question 18

Direction: Read the following passage carefully and answer the questions that follow.
The morning of June 27th was clear and sunny, with the fresh warmth of a full-summer day; the flowers were blossoming profusely, and the grass was richly green. The people of the village began to gather in the square, between the post office and the bank, around ten o’clock; in some towns, there were so many people that the lottery took two days and had to be started on June 20th, but in this village, where there were only about three hundred people, the whole lottery took less than two hours so that it could begin at ten o’clock in the morning and still be through in time to allow the villagers to get home for noon dinner.
The children assembled first, of course. The school was recently over for the summer, and the feeling of liberty sat uneasily on most of them; they tended to gather together quietly for a while before they broke into boisterous play, and their talk was still of the classroom and the teacher, of books and reprimands. Bobby Martin had already stuffed his pockets full of stones, and the other boys soon followed his example, selecting the smoothest and roundest stones; Bobby and Harry Jones and Dickie Delacroix—the villagers pronounced this name “Dellacroy”—eventually made a great pile of stones in one corner of the square and guarded it against the raids of the other boys. The girls stood aside, talking among themselves, looking over their shoulders at the boys, and the tiny children rolled in the dust or clung to the hands of their older brothers or sisters.
Soon the men began to gather, surveying their own children, speaking of planting and rain, tractors and taxes. They stood together, away from the pile of stones in the corner, and their jokes were quiet, and they smiled rather than laughed. The women, wearing faded house dresses and sweaters, came shortly after their menfolk. They greeted one another and exchanged bits of gossip as they went to join their husbands. Soon the women, standing by their husbands, began to call to their children, and the children came reluctantly, having to be called four or five times. Bobby Martin ducked under his mother’s grasping hand and ran, laughing, back to the pile of stones. His father spoke up sharply, and Bobby came quickly and took his place between his father and his oldest brother.

Q. The people of the village began to gather in the square, between the post office and the bank, around:

Detailed Solution for UP TET Paper 2 Mock Test - 4 (Science and Mathematics) - Question 18

Detailed Solution for UP TET Paper 2 Mock Test - 4 (Science and Mathematics) - Question 21

100% pure gold = 24 carat
50% pure gold = 12 carat = Rs 30,000
∴ 22 carat cost = 30,000 ÷ 12 × 22 = Rs 55,000
Detailed solution
GIVEN:
24 carat gold is hundred percent pure gold.
Price of 50% pure gold is Rs. 30,000
So, price of 1% pure gold = Rs. 600
CONCEPT:
In 22 carat gold pure gold is 22 parts out of 24 parts.
CALCULATION:

Percent of pure gold in 22 carat gold =(22/24)×100% = 91(2/3)%
Since, price of 1% pure gold = Rs. 600
∴ Price of pure gold in 22 carat Gold  = Rs.600 × 91(2/3)%
⇒ Price of pure gold in 22 carat Gold = Rs. 55,000

At which stage of cognitive development does the child acquire mathematical knowledge using real objects?

Detailed Solution for UP TET Paper 2 Mock Test - 4 (Science and Mathematics) - Question 29

According to Piaget, the child acquires mathematical knowledge using real objects in the concrete operational stage. In order to teach mathematics during this stage, teachers use manipulatives to explore concepts such as place value and arithmetical skills. These manipulatives can include algebra tiles, geoboards, dice, etc. As students use the materials, they acquire experiences that help lay the foundation for more advanced mathematical thinking.

During an experiment, Neha dipped a strip of X metal in a Y solution. After some time, she observed the solution becomes blue and a shining grayish-white. Then, what would be X and Y?

Detailed Solution for UP TET Paper 2 Mock Test - 4 (Science and Mathematics) - Question 30
  • When the red-brown of a copper strip is placed in a colorless solution of silver nitrate, then a shining greyish-white deposit of silver is formed on the copper strip and a solution becomes blue due to the formation of copper nitrate.
    Cu + 2AgNO3  →  Cu(NO3)2 + 2Ag
  • In this case, displacement reaction occurs because copper is more reactive than silver.
  • Therefore, copper displaces the silver from the silver nitrate compound.

Thus, the correct answer is X- Copper and Y- Silver nitrate.
