Concept:
- Map work is safest when each item is fixed first by its state and then by a landmark within that state, such as a river or a coastline.
- Working state by state prevents a correct name from being written in the wrong place.
Step 1: Work from the river for the first item.
The Chenab is one of the five rivers of the Punjab system and flows through Jammu and Kashmir. The major dam on it is the
Salal Dam, so the mark goes in the far north on the course of that river.
Step 2: Work from the coast for the second item.
Nuclear power stations need large volumes of cooling water, which is why so many of them stand on the coast. The Maharashtra plant is
Tarapur, on the Arabian Sea coast north of Mumbai.
Step 3: Work from the city for the third item.
Software parks grow where engineers, power and communications already exist, which in Tamil Nadu means
Chennai. Mark it on the eastern coast of the state.
Step 4: Work from the border for the fourth item.
Punjab lies in the north-west against the international border, and its international airport is at
Amritsar, named Raja Sansi or Sri Guru Ram Dass Jee International Airport.
Step 5: Check before handing in.
Confirm that a dam symbol sits on a river, an airport symbol sits inland at a city, and each label lies within the boundary of the state named in its clue. Attempt only three.
Final Answer: Salal Dam in Jammu and Kashmir, Tarapur nuclear power plant in Maharashtra, the Software Technology Park at Chennai, and the international airport at Amritsar in Punjab.
