UTET Paper 2 Mock Test - 7 (Science and Mathematics) - Question 3

If a previously learned task impedes a new task, which is being learnt. This transfer of learning will be:

Detailed Solution for UTET Paper 2 Mock Test - 7 (Science and Mathematics) - Question 3

If a previously learned task impedes a new task, which is being learnt. This transfer of learning will be negative transfer.
Transfer of learning is the process of applying or carrying over the knowledge, skills, habits, attitudes or other responses from one learning situation, in which they were initially acquired, to a different learning situation. 
Negative Transfer-

  • There are cases in which the previous learning interferes with subsequent learning.
  • In such cases, the carryover of knowledge or experience in one task interferes with further learning.
  • As a result of negative transfer, performance on one task may block performance on the subsequent task.
  • For example, a child’s experience in learning the plural of ‘house’ may inhibit his/her learning the plural of the word ‘mouse’. He/She may spell the plural of the word ‘mouse’ as ‘mouses’, instead of ‘mice’.
UTET Paper 2 Mock Test - 7 (Science and Mathematics) - Question 4

Which of the following statements is most appropriate about children making errors?

Detailed Solution for UTET Paper 2 Mock Test - 7 (Science and Mathematics) - Question 4

Children's errors are a window into how they think. They commit mistakes and learn in the process. These errors when committed by children and rectified by teachers/parents pave new way of learning, thinking, and doing things.

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

UTET Paper 2 Mock Test - 7 (Science and Mathematics) - Question 6

Knowing the naive conceptions that students bring to the classroom:

Detailed Solution for UTET Paper 2 Mock Test - 7 (Science and Mathematics) - Question 6

Naive Conceptions (also referred to as commonsense theory or folk theory) is a coherent set of knowledge and beliefs about a specific content domain (such as physics or psychology), which entails ontological commitments, attention to domain‐specific causal principles, and appeal to unobservable entities.

  • Teaching and learning are complements of each other.
  • Changes in teaching methods and techniques are required to make learning more effective.
  • As a teacher, it is very important to understand children's needs, curiosities, and problems.

By knowing the naive conceptions, the teacher can plan to make his teaching work more meaningful.
For example, if the child is comfortable reading and learning in the mother tongue if his concept is taught, then teaching can be made more meaningful for the teacher.
So, knowing the naive conceptions that students bring to the classroom, helps the teacher to plan to teach more meaningfully.

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

निर्देश: निम्नलिखित गद्यांश को ध्यान पूर्वक पढ़िए और विकल्पों में से उपयुक्त उत्तर चुनिए।
जाति-प्रथा को यदि श्रम-विभाजन मान लिया जाए तो यह स्वाभाविक विभाजन नहीं है क्योंकि यह मनुष्य की रुचि पर आधारित है। कुशल व्यक्ति या सक्षम श्रमिक समाज का निर्माण करने के लिए यह आवश्यक है कि हम व्यक्ति की क्षमता इस सीमा तक विकसित करें, जिससे वह अपने पेशे या कार्य का चुनाव स्वयं कर सके। इस सिद्धांत के विपरीत जाति-प्रथा का दूषित सिद्धांत यह है कि इससे मनुष्य के प्रशिक्षण अथवा उसकी निजी क्षमता का विचार किए बिना, दूसरे ही दृष्टिकोण जैसे माता-पिता के सामाजिक स्तर के अनुसार पहले से ही अर्थात गर्भधारण के समय से ही मनुष्य का पेशा निर्धारित कर दिया जाता है।
जाति-प्रथा पेशे का दोषपूर्ण पूर्वनिर्धारण ही नहीं करती, बल्कि मनुष्य को जीवन-भर के लिए एक पेशे में बाँध भी देती है, भले ही पेशा अनुपयुक्त या अपर्याप्त होने के कारण वह भूखों मर जाए। आधुनिक युग में यह स्थिति प्रायः आती है क्योंकि उद्योग धंधे की प्रक्रिया व तकनीक में निरंतर विकास और कभी-कभी अकस्मात परिवर्तन हो जाता है, जिसके कारण मनुष्य को अपना पेशा बदलने की आवश्यकता पड़ सकती है और यदि प्रतिकूल परिस्थितियों में भी मनुष्य को अपना पेशा बदलने की स्वतंत्रता न हो तो इसके लिए भूखे मरने के अलावा क्या चारा रह जाता है? हिंदू धर्म की जाति प्रथा किसी भी व्यक्ति को ऐसा पेशा चुनने की अनुमति नहीं देती है, जो उसका पैतृक पेशा न हो, भले ही वह उसमें पारंगत है। इस प्रकार पेशा-परिवर्तन की अनुमति न देकर जाति-प्रथा भारत में बेरोजगारी का एक प्रमुख व प्रत्यक्ष कारण बनी हुई है।

Q. भारत में जातिप्रथा बेरोजगारी का एक प्रमुख कारण किस प्रकार बन जाती है?

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

प्रस्तुत गद्यांश के अनुसार उपरोक्त सभी विकल्प उपयुक्त हैं क्योंकि गद्यांश में उपरोक्त सभी बातों को बेरोजगारी का कारण बताया गया है। इसलिए, विकल्प उपरोक्त सभी सही हैं। अन्य विकल्प असंगत हैं।
जातिप्रथा बेरोजगारी का कारण तब बन जाती है जब परंपरागत ढंग से किसी जाति-विशेष के द्वारा बनाए जा रहे उत्पाद को आज के औद्योगिक युग में नई तकनीक द्वारा बड़े पैमाने पर तैयार किया जाने लगता है। ऐसे में उस जाति-विशेष के लोग नई तकनीक के मुकाबले टिक नहीं पाते। उनका परंपरागत पेशा छिन जाता है, फिर भी उन्हें जाति-प्रथा पेशा बदलने की अनुमति नहीं देती। ऐसे में बेरोजगारी का बढ़ना स्वाभाविक है।

UTET Paper 2 Mock Test - 7 (Science and Mathematics) - Question 8

निर्देश: निम्नलिखित गद्यांश को ध्यानपूर्वक पढ़िए व प्रश्नों के उत्तर उपयुक्त विकल्पों द्वारा दीजिये- 
बारहसिंगा हिरण प्रजाति का बड़े आकार का शानदार वन्य पशु है। इस वन्य जीव को उत्तरप्रदेश की सरकार ने अपना राज्य पशु घोषित कर रखा है। दुर्लभ वन्य जीव होने के कारण इसे संकटग्रस्त सूची में रखा गया है। बारहसिंगा दुधवा राष्ट्र्रीय उद्यान, हस्तिनापुर अभ्यारण्य, असम के काजीरंगा राष्ट्रीय उद्यान और बंगाल के सुंदरवनों में भी पाया जाता है। मध्यप्रदेश के कान्हा राष्ट्रीय उद्यान में भी बारहसिंगा की दूसरी प्रजाति पाई जाती है। बारहसिंगा की कंधे तक की ऊँचाई 135 सेंटीमीटर होती है। इसका वजन लगभग 170 - 180 किलोग्राम तक होता है। यह प्रायः नम दलदली घास वाले क्षेत्रो में रहना पसंद करते है। बारहसिंगा प्रायः समूहों में पाए जाते है। इसके सींग 75 सेंटीमीटर लम्बे होते है। अधिकांश बारहसिंगो के सींगों में 10 से 14 तक शाखाएं होती है। अधिकतम 20 शाखाएँ वाले बारहसिंगा भी देखे गये हैं।

Q. इनमें से 'हिरन' किसका पर्यायवाची है?

UTET Paper 2 Mock Test - 7 (Science and Mathematics) - Question 9

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.

Q. Explain: 'when the chips are down'.

Detailed Solution for UTET Paper 2 Mock Test - 7 (Science and Mathematics) - Question 9

When the author says: 'But you can bet that when the chips are down, the yen stops at the top guy's desk', he implies that when a difficult situation arises, the responsibility falls upon the person who is at the top/who has the most authority'.
Thus from the statement, we find that Option (A) perfectly explains the phrase.

UTET Paper 2 Mock Test - 7 (Science and Mathematics) - Question 12

Language errors should be corrected when the goal is______.

Detailed Solution for UTET Paper 2 Mock Test - 7 (Science and Mathematics) - Question 12

Error: When a learner can’t master on a language, he is vulnerable to make errors. Errors are nothing but grammatically incorrect word, phrase, sentence, or structure. During second language acquisition, it is seen that students generally commit errors. So, the following should be noted:

  • When the goal is learning, indeed the errors should be corrected.
  • At the time of speaking (when learning is over), errors can be avoided to avoid interruptions.
  • Those errors should be corrected which impedes the intelligibility of the message, or frequently repeated, or that causes unfavourable reactions.
  • It can be corrected directly or using the discovery form.

Hence, we conclude that errors should be corrected when the goal is learning.

UTET Paper 2 Mock Test - 7 (Science and Mathematics) - Question 13

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. Which one of the following words is the most similar in the meaning to the word "tiny" as used in the passage (Para 2)?

Detailed Solution for UTET Paper 2 Mock Test - 7 (Science and Mathematics) - Question 13
  • Tiny: very small or diminutive, minute.
    Example: He's from a tiny town that you've probably never heard of.
  • Bitsy: very small in size.
    Example: It's just a bitsy blister, but it's right on my heel so that I feel it every time I take a step.

​Thus, "bitsy" is the most similar in meaning to "tiny".

UTET Paper 2 Mock Test - 7 (Science and Mathematics) - Question 14

Directions: Identify the antonym of the underlined word in the following sentence.

UTET Paper 2 Mock Test - 7 (Science and Mathematics) - Question 16

When a child has acquired all the language skills then he is said to be _________ in that language.

Detailed Solution for UTET Paper 2 Mock Test - 7 (Science and Mathematics) - Question 16

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.

UTET Paper 2 Mock Test - 7 (Science and Mathematics) - Question 21

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

Detailed Solution for UTET Paper 2 Mock Test - 7 (Science and Mathematics) - Question 21

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.

UTET Paper 2 Mock Test - 7 (Science and Mathematics) - Question 22

UTET Paper 2 Mock Test - 7 (Science and Mathematics) - Question 23

If 20 percent of P is added to 40 percent of Q, then the resultant comes as 80 percent of Q. P is what percentage of Q? 

Detailed Solution for UTET Paper 2 Mock Test - 7 (Science and Mathematics) - Question 23

Given:
20% of P + 40% of Q = 80% of Q
Formula Used:
Percentages can be expressed as fractions or decimals. For example, 20% can be written as 0.2 or 1/5.
Solution:
20% of P + 40% of Q = 80% of Q
0.2P + 0.4Q = 0.8Q
0.2P = 0.8Q - 0.4Q
0.2P = 0.4Q
Now we can solve for P/Q:
P/Q = 0.4 / 0.2
P/Q = 2
This tells us that P is equal to 2Q.
P is 200% of Q.

UTET Paper 2 Mock Test - 7 (Science and Mathematics) - Question 24

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

How can we say science is always tentative?

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

The word Tentative means the possibility of a change and science is always considered as tentative as there are always different discoveries and inventions that prove better than existing principles or theories.

  • Most of the theories in science can be revised or improved or changed or sometimes abandoned whenever there is some discovery or new pieces of evidence discovered which counter with the existing principles or theories.
  • For example, the Geocentric theory was revised as the Copernican model displaced the geocentric model of Ptolemy that had prevailed for centuries, which had placed Earth at the center of the Universe.

Therefore, we can say that science is always tentative as the theories of science are revised when new things are founded.
