Question 1

Long Form

Describe the perspective of astronauts when they see Earth from space and how it changes their thinking.

Astronauts like Group Captain Shubhanshu Shukla see the Earth as one single unit without any visible borders between countries.
From space the planet appears as a beautiful blue marble where no states or separate territories can be identified.
This view makes them realize that humans belong to one single family and the Earth is a home shared by all of us.
They stop seeing themselves just as citizens of one nation and start feeling like part of a larger global humanity.
For example Shukla mentioned that seeing Earth from the outside made him feel that no borders actually exist in our shared home.

Explain the concept of DIGIPIN and its practical benefits for people living in India.

DIGIPIN is a modern digital address system in India that uses a unique 10-character code for every small location.
It acts like a digital name tag for your home or school making it much easier to locate on a map.
This system is extremely helpful for essential services like ambulances that need to reach a patient quickly in an emergency.
It also assists postmen and delivery persons in finding specific houses even in crowded cities or remote villages where street names might be confusing.
For example a postman can use the 10-character code to navigate directly to a hidden house in a small village without getting lost.

Question 3

Long Form

Detail how nature operates without boundaries and provides examples of things that move freely across the world.

Nature does not follow the lines or borders drawn on maps by humans and everything in the environment is shared globally.
Elements like air water and clouds move across the sky and oceans regardless of which country they are passing over.
Seeds of plants can be carried by wind or birds to distant lands where they grow and become part of a new ecosystem.
Animals and birds also travel thousands of miles for food or better weather without needing any passports or legal permissions.
For example Rosy Starlings fly all the way from Russia and Mongolia to India every winter to escape the cold and find food.

Discuss the ways in which people around the world are connected through their daily lives and sharing.

Global trade connects us through the products we use like clothes that might have been made in a different country.

Ideas and inventions such as mathematical concepts or medical practices are shared across cultures to help everyone.

Describe the winter journey of Rosy Starlings and their contribution to Indian agriculture.

Rosy Starlings are small pink and black birds that perform an amazing migration journey every single year.
They fly thousands of kilometres starting from southern Russia and Mongolia to reach the warmer climate of India.
During their stay in India they move in large groups and look for specific insects to feed on in the fields.
They primarily eat locusts and grasshoppers which are pests that can destroy entire crops if left unchecked.
For example these birds act as helpful friends to Indian farmers by protecting their wheat or rice crops from insect damage.

Question 7

Long Form

Trace the historical journey of the Chilli and how it became a staple in Indian kitchens.

Chillies were not originally native to India and were found only in South America for a very long time.
Around 400 to 500 years ago Portuguese traders brought these plants across the oceans to the Indian subcontinent.
The chilli plants easily adapted to the Indian soil and warm climate and people started growing them in their gardens.
Indian people loved the spicy flavor so much that chillies quickly replaced black pepper in many traditional recipes.
For example today it is almost impossible to imagine a spicy Indian curry or a snack like samosa without the heat of chillies.

Question 8

Explain the significance of Indian cow breeds in Brazil and why they are highly respected there.

Long ago Portuguese traders exported Indian cow breeds like Gir Kankrej and Ongole to the distant land of Brazil.
These cows proved to be very successful because they were physically strong and could easily handle the hot Brazilian weather.
They provided high quality milk in large quantities which helped Brazil build a very strong dairy industry.
Currently more than 75 percent of Brazil's total milk production comes from these three specific Indian breeds.
For example the Brazilian government respects these cows so much that they have featured their images on national stamps and coins.
