Language acquired by the children helps in development of children. Since, children hear and learn from the sounds of speech even while they are still in the womb. Language learning accelerates once infants are born. This language learning affects cognitive development. Some effects are more specific to language whereas other are more general. Development is a multiple process which includes various things. And language is one of them.

The teacher is responsible to keep the students active, disciplined, attentive, participative during the teaching-learning process. For all this, the teacher has to keep the students motivated so that they remain self-disciplined and actively perform in the classroom activity. 

Questions are an aid in the learning process and hence questioning skill is one of the important teaching skills required to be developed to conduct a successful classroom session by the teacher. Effective teachers use productive questions to help students advance in their thinking and to construct their own understandings.

भाषा कौशल को एकीकृत तरीके से बेहतर तरीके से सीखा जा सकता है क्योंकि यह सभी कौशलों का फायदा उठाता है। उदाहरण के लिए, जब हम बोलते हैं, हम एक साथ सुनते भी हैं, जब हम लिखते हैं तो हम पढ़ भी रहे होते हैं।

Silent reading is most helpful in understanding the depth of meaning. By reading silently, understanding the words in their mind, they read further. It also increases the speed of reading and increases the ability to understand.

Differentiated instruction is a teaching approach that tailors instruction to students' different learning needs. It refers to teaching through various tasks such as creating charts, graphs, drawing, gathering information, and presenting them through pair or group work. 

• It is an approach to teaching that is intended to meet the learning needs of children with multiple intelligences & diverse abilities. 
• It helps teachers to plan and deliver instructions based on the different strengths and weaknesses of the children in their classroom. 
• It uses flexible grouping patterns; sometimes whole-class instruction occurs, and sometimes children work in small groups. 

'Mechanics' of language in speaking skills includes pronunciation, grammar and vocabulary.
Mechanics refers to the way in which something is done or operated. Speaking skills is the ability to express opinions or thoughts and feelings to a person or group verbally, whether face or by distance. Alternatively, speech is a natural means of communication between members of the public to express their thoughts and as a form of social behavior. 
Language learners need to recognize that speaking involves three areas of knowledge: 
Mechanics (pronunciation, grammar, and vocabulary): Using the right words in the right order with the correct pronunciation.
From the above, it is clear that the 'Mechanics' of language in speaking skills includes pronunciation, grammar, and vocabulary. It is important because it enables the speaker to use the right words in the right order with the correct pronunciation.

Sign language is the best method to teach students with hearing disability. Sign languages use the visual-manual modality to convey the meaning. A person, who cannot hear, can comprehend the gestures and gather the material conveyed to him or her.

Problem-solving is an important part of thinking processes. In general, a problem is any kind of conflict or difference between one situation and another that one wishes to produce, that which is the goal. 

• Problem-solving can be done either with or without insight and utilizes analytical, synthetic thinking along with metacognition.
• An individual uses various kinds of methods or strategies to solve problems.
• Some strategies when used take a long time but definitely give an answer. On the other hand, there are some other strategies that take lesser time but do not always guarantee success.

An exercise where words are left out of a shorter passage and the pupil must fill in the blanks with suitable words based on their reading, assesses their ability to comprehend.
Here the learners need to first understand the passage through reading and analyzing and then putting the correct words in blanks to make the sentence in a way that the meaning, usage of the words, and the sense of the sentence remain correct. For this activity, the learners need to comprehend the passage and therefore the ability to comprehend is under assessment here.

Learning Difficulties refers to a state when a person faces difficulty in learning. It may be due to physical limitations/disabilities such as - impairment in hearing, visual, low intellectual functioning, and inappropriate motor coordination.

The initial lines of the first paragraph state, "The people of the village began to gather in the square, between the post office and the bank, around ten o’clock."

A compound sentence is a sentence that has at least two independent clauses joined by a comma, semicolon or conjunction. An independent clause is a clause that has a subject and a verb and forms a complete thought.
Here, two independent clauses "the farmer was old" and "he could not plough..." are joined by the conjunction 'and'.

In free composition, the children are able to freely arrange their ideas in their own way and to choose their words freely. It is very helpful for higher-stage students.

There are compounds made up of the same elements, like carbon monoxide (CO) and carbon dioxide (CO2). Both compounds are made of carbon (C) atoms and oxygen (O) atoms. However, the ratios of carbon and oxygen in each compound are different. This illustrates the law of multiple proportions.

Mass Percent:

• It allows us to determine the relative number of atoms of a specific component present in a combination/solution.
• Mass Percent = (Mass of solute / Mass of solution) × 100%

Calculation:
Given: Mass of solute = 0.01%
Mass Percent = (Mass of solute / Mass of solution) × 100%
= (0.01/100) × 100 ​= 0.01%
= [0.01/ (0.01 + 99.99)] × 100 ​= 0.01%
Hence, the mass of solute =0.01 g  and the mass of solvent = 99.99 gms.

Given:
The ratio of the slant height and radius of right circular cone = 29 : 20
Volume = 4838.4 cm³
Formula used:
Volume of cone = 1/3πr²h
h² = √l² – r²
Calculation:
Let the ratio of the slant height and radius of right circular cone be 29x and 20x respectively
According to the question
h = √l² – r²
⇒ h = √29x² – 20x²
⇒ h = √(841 – 400)x²
⇒ h = √441x²
⇒ h = 21x cm
Now,
Volume of cone = 4838.4 π
⇒ (1/3 × π × 400x² × 21x) = 4838.4 π 
⇒ x³ = (172.8/100)
⇒ x³ = (1728/1000)
⇒ x = 12/10
Now,
The radius = 20x = (20 × 12/10) cm
⇒ 24 cm
∴ The required radius is 24 cm

• Cold-blooded Animals- are animals that cannot regulate their internal body temperature with the change in the environment.
• Warm-blooded animal-A warm-blooded animal, for example, a bird or a mammal, has a fairly high body temperature which does not change much and is not affected by the surrounding temperature.

About Rabbit:

• Oryctolagus cuniculus, scientfic name of rabbit.
• A baby rabbit is called a kit, a female is called a doe and a male is called a buck.
• A rabbit's teeth never stop growing.
• It belongs to the phylum Mammalia, so they are warm-blooded animals.
• Rabbits’ eyes are on the sides of their head, meaning they can see almost all the way around them.

• Hot air is lighter than cold air. 
• If there is a hot temperature in an area, the hot light air goes up. 
• This reduces air and hence reduced atmospheric pressure is created at that area. 
• Now, the empty space formed is occupied by the air coming from high-pressure areas. 
• The flow of air from a high-pressure area to a low-pressure area causes wind.
• The speed of the wind will be more if the pressure difference will be more. 

So, it is clear that the if atmospheric pressure increases, the wind speed will increase. 

Resistance symbol along with an arrow represents a variable resistor.

Heating and beating are the two processes that destroy the magnetic properties of a bar magnet.

• The basic solution can turn red litmus to blue.
• Add a few drops of solution from each text tube on litmus paper.
• The distilled water is neutral in nature and thus on adding it to litmus paper there is no color change in litmus paper. 
• With the addition of a few drops of acidic solution on blue litmus paper, the litmus paper turns blue to red.
• With the addition of a few drops of basic solution on red litmus paper, the litmus paper turns red to blue.

Vitamin B2

• ​A deficiency of vitamin B2 can cause skin disorders, hyperaemia (excess blood) and swelling of the mouth and throat, angular stomatitis (sores on the corners of the mouth) and hair loss.
• One of the eight B vitamins that are crucial for human health is vitamin B2, sometimes known as riboflavin.
• Grain, vegetables, and dairy products all contain it. It is essential for digesting food, absorbing other nutrients, and keeping tissues healthy.
• Every vitamin is either fat-soluble or water-soluble. Water-soluble vitamins are transported by the bloodstream, and excess amounts leave the body through urine. 

Option (1) is the correct option because they always believe in testing and experimenting things.

This will be considered as the most suitable option because there are more chances of getting different amount of results if we are getting results in percentages as compared to any other option.

• 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.
