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.

बच्चे निष्क्रिय गतिविधियों की अपेक्षा अन्तः क्रियात्मक गतिविधियों के माध्यम से अधिक सीखते हैं-सामाजिक संपर्क मायने रखता है- 

• ​​जब हम कहते हैं कि "सामाजिक संपर्क मायने रखता है," हम संचार की "आगे और पीछे" प्रकृति पर जोर दे रहे हैं।

• 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.

Computers are machines that allow us to perform complex tasks in an accurate, precise, and productive manner. Computer technology has evolved so much over time that nowadays, computers can aid in language learning also.
Computers have the capabilities to check the spellings, sentences, usage of words, and all other structures of the language in real time. It enables the students to realize and rectify their mistakes instantly and also they can use the computer to store the mistakes they have made to recall whatever errors were made in the past. So, it helps the learners by supporting them in language learning through real-time detailed error feedback.
Thus, it is concluded that computer technology enhances accuracy in students' writing by providing detailed error feedback.

• Drill work means memorizing a piece of text by repeating it. It does not require a computer, rather it needs effort from the learner.
• Spelling and grammar check is included in detailed error feedback.
• Formatting and font designs are not related to language learning or enhancing accuracy, rather they focus on the visual and aesthetic appearance of the text.

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

• 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.

• 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.

Science involves the process of observation, experiments, research, analysis, and investigation. It is a subject that is purely based upon facts that are proven with the help of various scientific techniques.

• The science curriculum refers to the overall subject matter of science to be taught in a specific period of time in a particular class. It includes all the co-curricular and recreational activities that are to be conducted in a science classroom.

Science includes only relative truths but not absolute truths. This means that science does not accept philosophical concepts.

• The reproductive parts of angiosperms are located in the flower. 
• The different parts of a flower are sepals, petals, stamens and pistil.
• Stamens and pistil are the reproductive parts of a flower that contain germ cells.
• Stamens represent the male reproductive part while the pistil is the female reproductive organ.
• The pistil is present in the centre of a flower and is the female reproductive part.
• It is made of three parts - Stigma, ovary and style.
• The swollen bottom part is the ovary, the middle elongated part is the style and the terminal part which may be sticky is the stigma.

The process of interpreting the world of knowledge to a pupil's mind is called the method of teaching. It helps a teacher to understand "what to teach", "how to teach", "how to approach it".

• 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.
