Question
Read the passage given below and make notes.
To match the best cities across the world, the Government of India initiated ‘smart cities’ to drive economic growth and improve the quality of life of people. The agenda under smart city promises to resolve urban sustainability problems. Urban forests provide a range of important ecosystem services that are critical for the sustainability of cities. Urban forestry, which is defined more as ‘Management of Trees’ contributes to the physiological, sociological and economic well-being of the society. Mangroves, lakes, grasslands, and forests in and around our cities, act as sponges that absorb the air and noise pollution and they present themselves as our cultural and recreational hotspots. However, these spots are rapidly being reclaimed and replaced in the name of development. Presence of urban green has shown to increase the economic value of the place.
Urban forests contribute to reduce the cost of building storm water drain systems for municipalities and neutralizing urban heat island effect. Plants not only provide shade but also help in regulating the micro-climate. They help regulate energy budgets, improve air quality, and curtail noise pollution. Trees, herbs, shrubs, and grasses arrest sedimentation and prevent other pollutants from entering our water systems. This will give a chance for our urban lakes and rivers to recover and help improve aquatic ecosystems. Biodiversity also gets a boost through the urban forestsand helps create corridors connecting the forest areas. High biodiversity areas can also help to build resilient ecosystems. Availability of forests within our urban areas gives an opportunity for children to connect to the natural environment and learn about native species.

A1. True or False
State whether the following statements are true or false:
(1) The author's new house was situated at Bangalore.
(2) The writer was delighted because their new house, was the biggest they ever lived.
One of the advantages of growing up in an Army household was the frequency with which we moved. 'Postings' came with predictable regularity every three years. What was unpredictable and therefore exciting was the suspense. Where would we go this time? Ambala, Pune, Dehradun, Allahabad, Tejpur, Bangalore, Yo! ............ In my short span of thirteen years we had moved lock. stock and barrel eleven times!
Every move meant change. New journeys, new places, new schools, my new books, new uniforms, new friends and new houses. We lived in tents, bashas, Nissen huts, flats and bungalows. No matter what the shape and size of the dwelling, mother soon put her own special stamp on it and transformed it into a familiar place - our home - complete with bright yellow-curtains, coffee-brown carpet, assorted pictures, hanging ferns and potted palms - providing a comforting sense of continuity in our essentially nomadic life.
I was thirteen, the year we moved to the Cantonment at Allahabad. In stark contrast to the razzle-dazzle of the city's commercial areas like Katra and Chowk, the Cantonment was a quiet, orderly place with broad tree-lined roads that still carried the names of long-dead Britishers. Our bungalow was on a sleepy by-lane called MacPherson Road. When we first saw it, my brothers and I were delighted. It was by far the biggest house we had ever lived in. The task of furnishing those huge, echoing rooms daunted Mother.

What do you think are the problems faced by those who change households frequently.
Read the following passage carefully and do the given activities:
A.1) True or False:
Write the statements and state whether they are true or false:
(i) Those who choose to live well must help others.
(ii) If neighbors grow inferior corn, cross-pollination will steadily improve the quality.
(iii) The farmer grew award-winning corn.
(iv) The reporter discovered that the farmer didn’t share his seed corn with his neighbors.
There once was a farmer who grew award-winning corn. Each year he entered his corn in the state fair where it won a blue ribbon. One year a newspaper reporter interviewed him and learned something interesting about how he grew it. The reporter discovered that the farmer shared his sweet corn with his neighbors. “How can you afford to share your best seed corn with your neighbors when they are entering corn in competition with yours each year?” the reporter asked.
“Why sir”, said the farmer, “didn’t you know? The wind picks up pollen from the ripening corn and swirls it from field to field. If my neighbors grow inferior corn, cross-pollination will steadily degrade the quality of my corn. If I am to grow good corn, I must help my neighbors grow good corn.” He is very much aware of the connectedness of life. His corn cannot improve unless his neighbor's corn also improves. So it is with our lives. Those who choose to live in peace must help their neighbors to live in peace. Those who choose to live well must help others to live well, for the value of a life is measured by the lives it touches.
The lesson for each of us is this: if we are to grow good corn, we must help our neighbors grow good corn.
