1.Question 1.Narahari created the following list of activities where technology is not used. Do you agree with him? If not, prove him wrong?
  • While singing a song
  • While cooking idli
  • While performing drama on the stage
  • While making garland for sale

Answer I do not agree with Narahari. I think his words are wrong. Technology is the practical application of knowledge in our everyday lives that leads to a new product or an improvement in the way something works or how something is done. There is no question of this and that. It is useful in all the activities

Question 2.Describe how the situation of labour has changed in powerlooms and mills. Do you think this change is beneficial to the labourers or to the owner? Give reasons for your answer?

Answer Textile mills have a large number of workers. They have workers unions or labourer unions. These unions fight for their rights and their better conditions. Powerlooms are small units. Compared to mills, powerlooms pay a very low salary. While mills pay workers monthly salary, workers in powerlooms are paid on piece rate basis. If there is any powercut, powerloom workers are not given salaries. Trade unions do not exist in most powerloom clusters. They have no pensions or other social security provisions. Due to these reasons, we can say that this change is beneficial to the owners

Question 3.What are the advantages of using CHs? Who benefits most? Why do farmers use CH?

Answer Advantages of using CHs

  • CH harvests the crop, threshes and cleans the grian from chaff
  • Use of CH helps in timely harvest of paddy. It takes less time, reduces the crop loss and helps farmers to tackle the peak time labour shortage
  • It also saves from vagaries of weather in coastal regions of Tamil Nadu, Andhra Pradesh and Odisha
  • The farmers are able to sow the second crop without much delay
  • Their dependency on labourers is also reduced. The farmers benefit most. Due to excess benefits by using CH, the farmers are using these CHs
Question 4.Changes in technology lead to changes in job opportunities. Do you agree with this statement? Why?

Answer I agree with this statement. Reason Technology with skills creates new jobs. e.g. Many landline companies and mobile companies were started. These companies export these phones to many countries. It created new jobs for young people to work in multi-national companies, producing mobile handsets, telephone booths, mobile sales, repair and recharge/top-up shops

Question 5.Prabhavathi feels that it is true that telephone technology has changed. She feels that new jobs are available to only educated persons. She also says that many people in India are not literate and hence modern technology is always biased to the educated. Do you agree with her? Give your reasons?

Answer I dont agree with Prabhavathi. Technology changed as she said, but it is useful to all. e.g. Now fishermen, rickshaw pullers etc., are using cell phones. With a minimum educational qualification so many are working as mechanics and technicians. Skill is needed in some works and technology instead of education

Question 6.In this chapter, changes in technology in three sectors are discussed. In the following table identify a different example for each of these sectors that is not discussed here?

Question 7.Read the paragraph under the heading "New Skills and New Jobs" and answer the following?

Many private companies including the government-owned ones provide both landline and mobile connections. Private companies continue to expand their share in the telecommunication services. Many companies are being established in India to manufacture handsets. These companies are now exporting to more than 80 countries around the world. The telephone/ mobile technology also came up with the need for new skills. It created new jobs for young people to work in multinational companies, producing mobile handsets, telephone booths, mobile sales, repair and recharge/ top-up shops

What are the newly created jobs for young people in your area

Answer Work in multinational companies, producing mobile handsets, telephone booths, mobile sales repair and recharge/top up shops are the newly created jobs for young people in our area

Question 8.Locate the following in the world map?
1) England 2) USA 3) India


Question 9.The people live in forest and adjacent to forest cannot afford to use latest technology. What measures do you suggest for improving their lives?

Answer We should not think using technology is only as improvement. The people living in forest and adjacent to forest are living in Natures lap. They are living in groups. All the blood relations live mostly in the same group. So they may not need phones or technology. The government should introduce technology to them. It should create better conditions to improve their lives. Then only they can lead an improvised life

Question 4.Do you think it is appropriate to use CHs in India where a large section of people working in agriculture as labourers, are poor, and there is so much problem of rural unemployment?
(Textbook Page No. 94)

Answer We can think in two angles about this problem. We can say that it is not appropriate by keeping the following in view

  • Rural unemployment
  • More dependency on agriculture. They may lose their livelihood
  • While keeping the development of the country in view - it is appropriate

Extensive farm mechanisation is widely prevalent in developed countries. These human resources can be used in other sectors by providing various job opportunities. This helps the development of the country

Question 5.In this chapter, we saw the photos of many women engaged in technology. Many of them like the one above does not have an Engineering degree. Conduct a debate in classroom what biases/ stereotypes exist about women getting educated as engineers?
(Textbook Page No. 99)

Answer "Women education brightens the future". Degree is an acknowledgement to their knowledge. There are so many skilled persons in many areas without qualifications, e.g. The village farmers have more knowledge than agricultural graduates. If the women acquire Engineering graduation, they will get higher positions. They educate their families. They lead their families and nation to development

Question 6.Who were the contributors to this industrial revolution?
(Textbook Page No. 90)


Inventions Their inventors
1. Spinning Jenny James Hargraves
2. Steam Engine James Watt
3. Steel Making Henry Bessem
4. Electricity and Light bulb Thomas Aiwa EdisonM
5. Telegraph Samuel F.B. Morse
6. Telephone Alexander Grahambell etc
These persons were contributors to this industrial revolution.
Question 7.Find out the story of the first steam engine. How did this lead to establishment of Railways in India? (Textbook Page No. 91)

Answer Steam Engines were used to pump water out of mines in England when James Watt was born. The discovery that steam could be harnessed and made to work is not credited to James Watt. We do not know that exactly who made that discovery, but we do know that the ancient Greeks had crude steam engines. James Watt however is credited with inventing the first practical steam engine. And so the history of the modern steam engine often begins with James Watt. There were no railway lines in India upto 1850. It was almost 100 years to the British. Colonial rule in India. They need transport facilities in this vast country. So they inaugurated the first railway line in 1853 which ran from Bombay to Thana. Since then the distance is reduced in India

Question 8.It is argued that new jobs can be created in rural areas through infrastructure works. Link roads, tanks, bunds etc., can be created through labour intensive schemes. If you live in rural area, find out if any such activities are being done and discuss if these will suffice the livelihoods of the people there?
(Textbook Page No. 94)

Answer A few years back the then government introduced a scheme Food for Work. Many works were undertaken in our village. Digging out soil from Cheruvus is one of those works. They used this soil to lay roads. They used quarry dust also in laying roads. Digging drainage canals was also a work in this scheme. But the labourers were given rice instead of money. One cannot lead their life only with rice. So they started exchanging the rice with money. As a result the purpose of the scheme got sidetracked. Even then we can say that this scheme helped the labourers in rural areas. These are helpful to them in non-crop season

Question 9.How have computers changed the life around you?
(Textbook Page No. 91)

Answer Computers have changed our lives in many different ways and aspects. Almost everyone depends on computers. People depend on computers for bank transactions, bus reservations etc. People may not even leave the houses for shopping.

The following solar instruments are used by our neighbours

  • Solar heaters
  • Solar lanterns / lamps
  • Solar cookers
  • Solar stoves
  • Solar batteries/inverters
  • The reason for not using them widely
  • Installation Price Cost of installing solar technology is too expensive
  • Variable sunlight Inconsistency of Sunshine throughout the year
  • An aesthetic appeal The opinions of the people who think solar panels look ugly
  • Day purpose only They can be used only in daytime only
  • Clouds If it is cloudy, we get less amount of energy
Question 11.In many villages, agricultural labourers, women labourers, in particular, were found to be upset seeing the operation of CH. Why?
(Textbook Page No. 94)
