What is the example of national integration that the author refers to?

Explanation

The make-up division of the Gemini Studios was an example of national integration. According to the author, this is so because people from different regions and religious groups worked together in the same department. The department was headed by a Bengali who was succeeded by a Maharashtrian. The other helpers included a Dharwar Kannadiga, an Andhra, a Madras Indian Christian, an Anglo-Burmese and the local Tamils.
