Concept:
- Software needs people, power and connectivity rather than ore, coal or a port for heavy cargo.
- Applying that test to Tamil Nadu points to the one city that supplies all three in full measure.
Step 1: Work out what the industry requires.
It requires engineers in large numbers, an uninterrupted power supply, high speed data links and an airport for international travel. Raw materials play almost no part.
Step 2: Apply the test to the state.
Among the cities of Tamil Nadu,
Chennai has the densest cluster of engineering and technical institutions, an international airport and the administrative weight of a state capital.
Step 3: Confirm the result.
The Software Technology Park of the state is therefore at Chennai, and the city ranks among the leading centres of the information technology industry in India.
Step 4: Fix the position for map work.
Chennai lies on the Coromandel coast, on the eastern side of Tamil Nadu, and that is where the symbol should be placed.
Final Answer: The Software Technology Park of Tamil Nadu is at Chennai.
