CG TET Paper 2 Mock Test - 9 (Science and Mathematics) - Question 1

Which of the following stages of development is called as 'A unique stage of emotional development' by Cole and Bruce?

Detailed Solution for CG TET Paper 2 Mock Test - 9 (Science and Mathematics) - Question 1

Development: It is a broad term that includes a series of qualitative and progressive changes. These qualitative changes lead to the enhancement of various abilities and enable one to function effectively.

  • Emotions: These are the feelings generated as an effect of experiences, or relationships of an individual with others. They are instinctive reactions that come naturally to all and contribute to personal and social adjustments of an individual.

According to Cole and Bruce, childhood is a unique stage of emotional development.

  • Emotional development relies heavily on the process of socialization and proceeds in a stepwise manner.
  • Basic emotions such as fear, disgust, happiness, sadness, surprise, anger, and interest, are present since birth.
  • During childhood, mood tantrums are pretty common.
  • Toddlers have a tendency to have fast temper swings. While their emotions may be very intense, these emotions additionally have a tendency to be pretty short-lived.
  • One might be stunned at how an infant can go from screaming hysterically about a toy at one second to sitting in the front of the TV quietly looking at a favorite show simply moments later.
  • Children at this age are very possessive and have difficulty in sharing.

So, it could be concluded that 'Childhood' is called as 'A unique stage of emotional development' by Cole and Bruce.

Detailed Solution for CG TET Paper 2 Mock Test - 9 (Science and Mathematics) - Question 3

In a class individual learners differ from each other in terms of rate of development.
The rate of development of an individual child is different from that of another child. This principle is known as the ‘principle of individual differences’. For instance, some children may learn to walk in 8 months, while some may take more than a year to start walking. 
It is important for teachers to know variables such as physical characteristics, intelligence, perception, gender, ability, learning styles, which are individual differences of learners. An effective and productive learning-teaching process can be planned by considering these individual differences of students.

The digital revolution has indisputably reshaped our society, permeating virtually every facet of life. We live in a hyperconnected era, where the boundary between the real and virtual worlds is increasingly blurred. Though its benefits are myriad, it's worth pausing to consider the potential downsides of this digital immersion.
On the one hand, technology has democratized information, fostering global connectivity and accessibility. The internet, smartphones, and various digital platforms have empowered us with the ability to learn, communicate, and collaborate like never before. They have catapulted us into an era of unprecedented convenience and opportunity, where we can virtually traverse the globe with a simple click.
Yet, this digital immersion also comes with pitfalls. The unending influx of information can overwhelm our cognitive capabilities, leading to information overload. The constant bombardment of updates, notifications, and messages can disrupt our focus, leading to a condition known as "digital fatigue." Further, it's alarming to see the increasing prevalence of cyberbullying, privacy breaches, and disinformation campaigns, which have severe consequences on our societal harmony.
The digital revolution is a double-edged sword. It grants us unparalleled access to knowledge, yet it can also breed distraction, misinformation, and anxiety. We need to strike a balance, leveraging the best of what technology offers while mitigating its downsides. As we continue to navigate this digital landscape, it's crucial to remember that technology is merely a tool—it's how we use it that ultimately defines its impact.

CG TET Paper 2 Mock Test - 9 (Science and Mathematics) - Question 12

The knowledge can be stored in mind permanently, if it is gained through practical experience. This statement reflects the principle of_____.

Detailed Solution for CG TET Paper 2 Mock Test - 9 (Science and Mathematics) - Question 12

The Principle of Concreteness: This principle is based on the assumption that knowledge can be stored in the mind permanently if it is gained through practical experience. 
A child can remember ‘lotus’ more if he has seen the flower himself than when has not.
The teacher, therefore, should begin with concrete things.
The teacher can use either classroom material or should bring with him handy material. Besides nouns, others, e. g., adjectives, pronouns, prepositions, conjunctions, verbs, adverbs should also be taught keeping in mind this principle.

CG TET Paper 2 Mock Test - 9 (Science and Mathematics) - Question 13

Direction: Read the passage given below and answer the questions that follow by selecting the most appropriate options:
(1) We embarked along the sapphire route along National Highway 17 for a sun-soaked holiday. This route along Karnataka’s Karavali coast is India’s best beach and temple country. Flanked by the soaring Western Ghats on the east and the Arabian Sea on the west, the Karavali stretch is a scenic treat all the way.
(2) The first halt in our coastal circuit in Uttara Kannada district was Bhatkal. Bhatkal is where Konkani begins to share space with Tulu. A 4-km drive out of town took us to the beach and the small fishing wharf. At the bazaar, we tried out the two local specialities – date halwa and a salted roti. One also shouldn’t miss the Bhatkal biriyani.
(3) Gokarna is a charming little town with temples, a wide expanse of beach, two principal streets and clusters of traditional tile-roofed brick houses. You’ll also find quaint Udupi food joints, souvenir shops, and cyber cafes here.
(4) Once the ‘temple fatigue’ set in, we indulged in some sedate sea-watching. Om beach, one of Gokarna’s famed five, takes the shape of an ‘Om’, a spiritual symbol. The road twists through alleys, past people’s houses, temple chariots and ‘Way to Beach’ signs. The other pristine beaches, wedged between gigantic cliffs that protrude like delicate fingers into the sea, are Gokarna, Kudle, Half Moon and Paradise.
(5) The last halt in our coastal itinerary was Karwar. Karwar was the erstwhile trading outpost of foreigners. It is said that even the great explorer Vasco da Gama walked on the golden sands of Karwar. Apart from the excellent harbour, four beaches that offer sun, sand, surf and sport and five islands, Karwar has much more to offer.
(6) A short boat ride away you’ll find the excellent Devbagh Beach and five idyllic islands. With its pristine beach, and an eco-friendly resort with ethnic log huts, it is a romantic hideaway offering complete privacy and solitude sans the five-star trappings.
(7) We followed Tagore’s footsteps and took a boat cruise up the Kali from the mouth. We spotted dolphins as they gracefully dived into azure waters. From the island one can have a gorgeous view of the sea, sand and the neighbouring islands. As we returned from our coastal odyssey, we realised Karnataka is not short of fabulous beaches but lacks salesmen of its ravishing beauty.

Q. What is the synonym of 'fatigue'?

Detailed Solution for CG TET Paper 2 Mock Test - 9 (Science and Mathematics) - Question 13

The meaning of 'fatigue' is the feeling of being extremely tired. The synonyms of fatigue are exhaustion, weariness, fatigue, maceration, lassitude, depletion.

CG TET Paper 2 Mock Test - 9 (Science and Mathematics) - Question 14

Which of the following is not a technique of teaching vocabulary?

Detailed Solution for CG TET Paper 2 Mock Test - 9 (Science and Mathematics) - Question 14

Vocabulary is the knowledge of words and word meanings. As Steven Stahl puts it, "Vocabulary knowledge is knowledge; the knowledge of a word not only implies a definition but also implies how that word fits into the world."

  • Vocabulary knowledge is not something that can ever be fully mastered. it is something that expands and deepens over the course of a lifetime.
  • Vocabulary is acquired incidentally through indirect exposure to words and intentionally through explicit instruction in specific words and word-learning strategies.
CG TET Paper 2 Mock Test - 9 (Science and Mathematics) - Question 15

CG TET Paper 2 Mock Test - 9 (Science and Mathematics) - Question 16

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. Select the segment of the sentence that contains the grammatical error. If there is no error, mark "D" as your answer.
The morning of June 27th was clear and sunny, (A)/  with the fresh warmth of a full-summer day; (B)/ the flowers were blossoming profusely, and the grass was rich green. (C)/ No Error (D)

Detailed Solution for CG TET Paper 2 Mock Test - 9 (Science and Mathematics) - Question 16

The error lies in the usage of the adjective rich instead of the adverb richly.
An Adverb is a word that describes, modifies, or gives more information about a verb, adjective, adverb, or phrase.
Example: She smiled cheerfully.
The word green refers to the color of the grass.
In the given sentence, the word green is used as an adjective, and rich is also used as an adjective, which is grammatically wrong. 
Here, the adverb richly should be used to modify the adjective green as how much green the grass is. 
So, the correct sentence is: 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.

CG TET Paper 2 Mock Test - 9 (Science and Mathematics) - Question 17

Directions: Change the sentence into positive degree.

CG TET Paper 2 Mock Test - 9 (Science and Mathematics) - Question 20

Metal 'X' displaces metal 'Y' from its salt solution but is not able to displace metal 'Z' from its salt solution. Identify the most reactive metal.

Detailed Solution for CG TET Paper 2 Mock Test - 9 (Science and Mathematics) - Question 20

Metal activity series:

  • The metals are arranged in an activity order that is known as the metal activity series.
  • The more active metals are present at the top of the series whereas the less active metals are put at the end of the series.
  • The metal activity series is as follows- 


Metals on top of the activity series can displace metals at the bottom and they are highly reactive as compared to metals at the bottom of the series.

  • Metal 'X' displaces metal 'Y' from its salt solution, so 'X' is more reactive than 'Y'.
  • Metal 'X' Can not displace metal 'Z' from its salt solution, so 'Z' is more reactive than 'X'.

So reactivity order of these metals will be:
Z > X >Y.
So, metal 'Z' will be the most reactive metal among all.

Detailed Solution for CG TET Paper 2 Mock Test - 9 (Science and Mathematics) - Question 29

Given:
A ∶ B  = 8 ∶ 7
Concept used:
Mode = 3 Median - 2 Mean
Calculation:
Let A and B be 8a and 7a
Mode = 3 × 7a - 2 × 8a
⇒ Mode = 21a - 16a
⇒ Mode = 5a i.e C
So, B : C = 7a : 5a
⇒ 7 : 5
∴ The ratio of B ∶ C is 7 : 5.
