Answer:
My response would be unambigous.
I'd stick with describing my native country.
Having explained the foundational elements of my culture, I'd go on to add one or two examples of how, pesonally, my behaviour has been shaped by other cultures. In other words, I'd identify with one culture but explain how other cultures have contributed to shaping my thinking.
Step-by-step explanation:
For example,
Q: Where are you from?
A: I am from the Eastern Parts of Nigeria called the Igbo. Nigeria is in West Africa and is regarded as the most populous black nation in the world.
Q: Where do you feel you belong?
A: I have strong Igbo roots. However, given my years of travelling, education and experience, my attitudes and thinking have evolved, being shaped by interesting ideas from other climes that are worthy of emulation.
Q: Describe your cultures as they define your identity
A: The Igbo people are very industrious and have a regard for acquiring good education.
It is not uncommon to find an Igbo man who besides his day job also has a business which provides other streams of income.
Igbo people are predominantly very warm and welcoming, and are not afraid to take the lead when the situation calls for it.
On a broader scale, we value communal and family ties.
Cheers!
