उत्तर
I went to the stall dealing with the adulteration of food. There were quite a number of parents in front of this stall, and I was curious to see what was being explained. The stall had an attractive poster at the entrance. It said, 'Do you know what you are eating?' Then it told us about the presence of adulterants in the food we eat. how widespread adulteration is and how it affects our systems. There were a variety of other charts put up around the stall. They told us of the adulterants that were present in the common food items that we used every day - like milk, oil, spices, etc, and how to detect them.
The four pairs of students in the stall had different food stuff in front of them. The first pair had chilli powder - adulterated chilli powder in one bowl and pure chilli powder in another bowl. There was a beaker of water kept handy. Then they showed the audience a simple way to test for artificial colouring. You merely added the chilli powder to the water. If it was pure, the water did not change colour. If it was adulterated, the artificial colorants descended as colour streaks.
The other three pairs dealt with
- the testing of green peas for artificial colour
- the testing of asafoetida (bing) for starch and
- the testing of powdered spices for starch. The tests were extremely simple but effective. They could easily be done at home. If the testing was more complicated, the details were given in the charts. The harts were clear and interesting and the students were very confident and thorough about their subject. Everyone was impressed.

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.
