Concept:
- Map work becomes reliable if each item is fixed by the state named in the clue and then by a landmark inside that state, such as a river, a border or a coastline.
- Working state by state also prevents a correct name from being written in the wrong place.
Step 1: Work from the clue to the state and then to the spot, for Gujarat.
The clue names the Narmada river and Gujarat. The largest dam on that river is the
Sardar Sarovar Dam. Trace the Narmada from Madhya Pradesh into southern Gujarat and mark the dam on its course before it reaches the sea.
Step 2: Do the same for Punjab.
Punjab lies in the north-west, sharing a border with Pakistan. Its international airport is at
Amritsar, close to that border, and is named Raja Sansi or Sri Guru Ram Dass Jee International Airport. Place the airport symbol there.
Step 3: Do the same for Karnataka.
Karnataka lies in the southern peninsula. Its Software Technology Park is at
Bengaluru, in the south-eastern interior of the state, which is why the city is known as the technology capital of the country.
Step 4: Do the same for Odisha.
Odisha lies on the eastern coast facing the Bay of Bengal, so its major port must be on that coastline. The port is
Paradip, located near where the Mahanadi meets the sea.
Step 5: Check the work before finishing.
Each name should sit inside its own state, each should carry the correct symbol, and exactly three items should be attempted since the question asks for any three.
Final Answer: Sardar Sarovar Dam on the Narmada in Gujarat, Amritsar international airport in Punjab, the Software Technology Park at Bengaluru in Karnataka, and the sea port of Paradip in Odisha.
