Answer:

IV. Answer the following questions.

Question 1.
Explain how stifling is done. What is the purpose of stifling of cocoons?
Answer:

1. When the eggs are hatched the larvae come out, these are kept in chandrikalu.
2. Chandrikalu are specialized cane structures where mulberry leaves are also kept for larval feeding.
3. This larva forms the cocoon. These are used for obtaining silk fibres.
4. After 2 – 3 days cocoons formation, farmers remove them from chandrikalu and treat them under steam for 10 to 15 minutes.
5. The process of killing larvae inside the cocoon by putting them in steam is called stifling.

Importance of stifling:
The larvae in the cocoons have to be killed by stifling otherwise larvae inside cocoons will come out by breaking open the cocoons.

1. Hence, we can not derive continuous thread of silk. This will reduce the quality of silk fibre.
2. Stiffled cocoons can be stored for a long time and can be sold in market.

Question 2.
Differentiate between Animal fibres and Plant fibres based on their properties.
Answer:

Question 3.
Analyse the advantages and disadvantages in usage of clothes made of synthetic fibres. Which type of fabric you prefer to use? Why?
Answer:
I prefer to use jute fabric because it is environmentally friendly.

Advantages of using synthetic fibres :

1. Synthetic fibres are light, soft and smooth.
2. They are more durable when compared to natural fibres.
3. Maintenance of dresses made of synthetic fibres is relatively easier.
4. These are available at a cheaper price as their production is quite abundant and economical.

Disadvantages of using synthetic fibres :

1. Except Rayon, all other synthetic fibres are made of chemicals. So, their production leads to Environmental pollution.
2. Even after their disposal they won’t mix in soils for years and they release harmful chemicals into the soil.

Question 4.
What happens if stifling is not done to silk moth cocoons?
(OR)
What will happen if cocoon is not boileicl?
(OR)
Generally larvae of silk moth are killed by a process of stiffling to collect silk from cocoon. What will happen if cocoon is not boiled?
Answer:

1. If cocoon is not boiled, the larva inside the cocoon grows and cuts its way out after growing into a moth and spoil the cocoon.
2. We cannot derive continuous thread of silk.
3. This will reduce the quality of silk fabric.

Question 5.
Draw a well labelled diagram to explain life cycle of silk moth. Which stage in life of silk moth is important for making silk? Why?
Answer:

1. Among the four stages of silk moth, larva stage is important for obtaining silk.
2. In this stage, silk worm secrets a ghee like substance containing protein. This protein dries up on exposure to air to form silk fibre.
3. Like this way, silk worm completely covers its body with silk fibre. This looks like a capsule known as cocoon (pattukaya).
4. After stiffling process we get silk from cocoons.

Question 6.
What precautions do you suggest a shearer to take while shearing an animal to prevent hurting them?
Answer:

1. Cutters and combs should be sharp and they should be cleaned, resharpened and lubricated after each job of shearing.
2. The shearing floor should be clean and free of straw and debris.
3. Sheep must be dry before shearing.
4. Shearing must be done in shade to prevent heat stress.
5. Prevent cuts to the animal’s skin by taking time while shearing and carefully clipping the wool so as to not get too close to the sheep’s skin.

Question 7.
Describe your views on preparation of silk by killing the larvae. What ways do you suggest to prevent this activity towards silk moth?
Answer:

1. I feel very unhappy on the methods used for producing silk by killing the larvae of silk moths.
2. I feel ashamed as a human being, for killing the innocent larvae in the boiled water for getting silk.
3. It is better to avoid these practices for getting silk.
4. We should encourage Ahimsa silk which is obtained in non – violent way. In this method, the pupa of silk worm is allowed to hatch and the left over cocoon is then used to derive silk. This method of silk production is introduced by Kusuma Rajaiah, a handloom technologist and a former employee in AP Handloom department.
5. We should encourage the trails executing to find sources of silk other than silk worms.
6. A Manipuri silk inventor named Tongbran Bijay Santhi, introduced to draw silk like threads from Lotus stem. We should welcome this type of inventors to pave new ways for getting silk.

Think about the dresses we prefer to wear ip winter or when we are going to visit cooler places. Which natural fibre are they made of? Why do we choose woolen dresses like sweaters, shawls, scarfs etc. Wool is a bad conductor of heat. It won’t allow our body to lose heat.
Answer:

1. Wool is a poor conductor of heat. Air trapped in between the woolen fibres and our body prevents the flow of heat from our body to our surroundings.
2. So we feel hot and are protected from cold.
3. Woolen cloth also helps to do use fire.

C. Refer to a dictionary and match the following nouns with their collective nouns. One is done for you.

In this sentence, the noun ‘herd’ takes the singular verb ‘is crossing’ though there are many elephants. Here the word ‘herd’ is considered as a single unit.

Grammar

A. Adverb and its Placement
Read the sentences from the text.

I duly presented it to my wife.

In the sentence above the word ‘duly’ is used to confirm the action giving a ‘present’. Such words are called adverbs of confirmation or negation.

The words such as certainly, definitely, surely, indeed and undoubtedly used to confirm the action. So they are adverbs of confirmation.

The words such as never, no, not are adverbs of negation.

These words are usually placed between subject and main verb or auxiliary and main verbs.

Position of Adverbs
There are three positions of adverbs.

1. At the beginning
a) Tomorrow, we have a yoga class.
b) Surely, I’ll help you.

2. In the middle
a) He seldom makes a mistake.
b) We often go to temple.

3. At the end

B. Voice

Read the following sentences from the text.
1) An island was made for Baba.
2) Baba ate everything.

Notice the ‘subjects’ and the ‘action words’ in the sentences above.

After studying the table, we can say that in sentence ‘1’ the subject is not doing the action ‘make’ and in sentence ‘2’ the subject is doing the action ‘eat’.

If the subject is the doer of the action, we say the sentence is in active voice and if the subject is not the doer of the action the sentence is in passive form.

So here sentence ‘1’ is in passive voice and ‘2’ in active.

Let’s see how imperative sentences are written in passive form.

The imperative sentences can be written in passive voice in the following way.
Active : Do it at once.
Passive : Let it be done at once.
Active : Open the door.
Passive : Let the door be opened.
Active : Do not beat the bench.
Passive : Let the bench not be beaten.

Change the following into passive voice.

1. Bring a glass of water. …………………………………….
2. Do not pick the paper. …………………………………….
3. Give him the book. …………………………………….
4. Do not write the questions. …………………………………….
5. Do not waste water. …………………………………….
6. Plant more saplings on either side of the road. …………………………………….
Answer:

1. Let a glass of water be brought.
2. Let the paper not be picked.
3. Let the book be given to him.
4. Let the questions not be written.
5. Let water not be wasted.
6. Let more saplings be planted on either side of the road.

The Bond of Love Summary

The Bond of Love is about the emotional bond which the author’s wife and her pet bear share between them. The author rescued the baby bear in an accident and gifted it to his wife. After that, they were bonding like he was their child and the author’s wife loves him a lot. We see that the family nourished him and helped him grow. As Bruno starts growing up, he bonded with everyone, from the children to the pet dogs. He had his own bed and would play around with the little-ones.all day.

However, in an accident, one day he ate poison which was to kill rats. After consum-ing poison, Bruno got paralysed and after proper treatment, they were able to save him. Soon, life became normal when in another incident; he drank up a whole gallon of old engine oil meant for termites. But, surprisingly, it did not affect Bruno. Thus, Bruno started growing in size but was equally sweet and playfyl. Upon growing, they changed his name to ‘Baba’ which meant ‘a small boy’ in the Hindi language. He picked up a few tricks growing up and entertained everyone. Nonetheless, his size was a problem and being an animal, he was a threat to the children.

Therefore, everyone except the wife was ready to send him to a zoo as he was not fit as a pet now. While she did not agree initially, she had to give in for everyone’s safety. After the official paperwork, he was ready for the Mysore Zoo. The wife missed him terribly and asked everyone to visit the zoo about his well-being. She learned that Baba was not eating well and remained sad all day. So, after three months, she decides to visit him herself. Although everyone told her that Baba would not recognize her, he surprised everyone by recognizing her in a jiffy.

After that, she petted and pampered him and spent a lot of time with him. However, she could not leave him so she decided to take him back. After the formalities, she finally brought him back home and made a special island for him with deep dry pit and his belongings. So, she finally reunited with Baba and spent her days petting him and making him sleep in her lap, sharing the true bond of love.
