Infrastructure: Engine of India’s Development Class 7 Question Answer (In-Text)
The Big Questions? (Page 169)
Question 1.
What is physical infrastructure, and how has it transformed over the years in India?
Answer:
Physical infrastructure refers to the tangible systems that support daily life—such as roads, bridges, railways, airports, ports, electricity networks, water pipelines, communication systems, and energy facilities. Over the years, India has transformed its infrastructure by building expressways, expanding the railway network, increasing electrification, developing modern airports, constructing long bridges, and improving communication technologies such as fibre-optic networks and mobile connectivity.
India now has one of the world’s largest road and railway networks, over 150 airports, extensive shipping facilities, and advanced digital systems that enable quick communication. This evolution has strengthened connectivity across cities, villages, and remote areas, making travel faster, safer, and more efficient.
Question 2.
How has the expansion in infrastructure affected the quality of life for individuals and communities?
Answer:
Infrastructure expansion has greatly improved the ease of living for individuals and communities. Better roads and transport systems allow people to travel quickly to schools, workplaces, hospitals, and markets. Improved irrigation systems, cold storage, and market access help farmers earn better incomes.
Communication networks enable online education, digital payments, e-govemance services, and instant information sharing, even in remote villages. Airports, metros, and railways reduce travel time and provide safer, cleaner modes of transport. Thus, modem infrastructure enhances employment opportunities, supports emergency response, reduces isolation, and raises living standards across India.
Question 3.
What is the role of infrastructure in the development and economic prosperity of the nation?
Answer:
Infrastructure is the backbone of economic development because it enables smooth movement of goods, services, and people. Efficient transportation systems support trade within India and with other countries, boosting industries, tourism, and employment. Ports and airports facilitate large-scale import and export activities, strengthening India’s global economic links.
Reliable communication systems promote digital businesses, e-commerce, and government service delivery. Energy infrastructure powers industries, agriculture, and homes, while social infrastructure (schools, hospitals, training centres) develops human capital. A nation with strong infrastructure attracts investment, generates jobs, and increases productivity—creating long-term economic prosperity.
Think About It
Question 1.
What might happen to Satish’s efforts if any part of the infrastructure is missing? (Page 173)
Answer:
Satish depends on canals, electric water pumps, good roads, cold storage, and internet access to grow, preserve, and sell his tomatoes. If any part of this infrastructure is missing such as irrigation, storage, transport, or communication his produce may spoil, he may get lower prices, or he may not reach the market on time. This would reduce his income and make farming more difficult and unpredictable.
Question 2.
What happens when a new highway is built near a village? How does it impact the lives of the people living nearby? (Page 173)
Answer:
A new highway near a village greatly improves connectivity by allowing people and goods to reach cities”, markets, hospitals, and schools faster. It creates new economic opportunities such as shops, transport services, and tourism.
Farmers can transport crops quickly before they spoil, and villagers gain better access to jobs and services. Hence, it enhances mobility, reduces travel time, and improves the quality of life for the community.
Question 3.
Imagine if there were no internet or phone services.
How would this affect people’s ability to work or learn? (Page 173)
Answer:
Without internet or phone services, communication would become slow and difficult, making it hard for people to coordinate work or run businesses. Students would lose access to online classes, educational videos, digital libraries, and important learning resources. People could not use digital payments, e-govemance services, or emergency alerts. Thus, the lack of connectivity would isolate communities and limit opportunities for growth, learning, and economic participation.
Question 4.
Which parts of communications infrastructure process do you think are easiest to see in real life, and which are completely invisible? (Page 185)
Answer:
The easiest parts of the communication process to see in real life are the mobile towers, phones, Wi-Fi routers, and electricity lines around us. We can also see people using their phones, telecommunication shops, and sometimes fibre-optic cables being laid along roads.
The invisible parts include the signals travelling through underground fibre cables, the satellites in space transmitting data, and the large data centres and servers where our messages get processed. These parts work silently in the background, so even though we depend on them every day, we cannot see them directly.
Question 5.
Look at the picture of evolution of the telephone
Question 5.
Look at the picture of evolution of the telephone and answer the following questions: (Page 187)
(i) In the 1990s, mobile calls in India cost up to ₹ 17 per minute, with charges even for incoming calls. Today, India has some of the world’s cheapest mobile and internet rates. How do you think this became possible? (Page 187)
Answer:
In the 1990s, mobile networks were new, and technology was limited, so the cost of operating services was very high. Over the years, India expanded its communication infrastructure with more mobile towers, fibre-optic cables, satellites, and advanced digital systems.
As technology improved and competition among telecom companies increased, the cost of providing services decreased. With millions of users now subscribing, companies could offer data and calling services at much lower prices. This combination of better infrastructure, large-scale usage, and technological innovation made India one of the cheapest mobile and internet markets in the world.
(ii) In 2025, there are 1,160 million wireless telephone subscribers and nearly 900 million internet connections in India.
Answer:
This shows that communication technology has become widespread and accessible across India. Even people in remote villages now use mobile phones and the internet for education, banking, shopping, work, and entertainment. It also reflects how strong and vast the communication infrastructure has become, with towers, cables, satellites, and data centres supporting millions of daily users.
(iii) Ask your family or people in the neighbourhood how they sent long-distance messages before mobile phones were introduced. What has been their experience of using the first telephone or mobile phone?
Answer:
Before mobile phones, people relied on letters, postcards, landline telephones, telegraphs, or sometimes trunk calls that took a long time to connect. Many families had to go to a public phone booth to make long-distance calls. When the first telephones or early mobile phones arrived, calls were very expensive and often unreliable.
People remember waiting for connections, facing network issues, and limiting their conversations because of per-minute charges. However, they also recall the excitement of being able to speak instantly with someone far away, which felt revolutionary compared to waiting days or weeks for a letter.
Question 6.
Do you see other types of infrastructure around you like schools, colleges, training centres, hospitals, health centres, police stations, fire stations, cotirts, parks, libraries, community centres and so on? This is known as social infrastructure. How do you think it supports the wellbeing and development of communities and society? (Page 188)
Answer:
Yes, we can see many types of social infrastructure around us such as schools, hospitals, colleges, parks, libraries, police stations, and community centres. These facilities play a very important role in supporting the well-being and development of communities.
Schools and colleges provide education, which helps children and youth gain knowledge and skills for future employment. Hospitals and health centres ensure that people receive timely medical care, improving public health. Parks, libraries, and community centres offer spaces for recreation, learning, and social interaction, which are important for mental and emotional wellbeing. Police stations, fire stations, and courts maintain safety, security, and justice in society.
Thus, social infrastructure helps create healthier, safer, and more educated communities, allowing people to live better lives and contribute positively to the nation’s development.
