<u>Answer:</u>

No, the Tully-Fisher technique wouldn't have worked in such a scenario.

<u>Explanation:</u>

  • For the Tully-Fisher technique to work, it is required that our view of the stars allows us to read their motion.
  • If a galaxy would be in a position facing perfectly towards us, it would've been impossible to read whether the galaxy is moving towards us or away from us.
  • In that case, the Tully-Fisher technique would fail and our distance from the galaxy would be incalculable.

The growth of port cities in colonies of Southeast Asia brought new immigrants to the region from
andreyandreev [35.5K]

The growth of port cities in Southeast Asia brought lot of new immigrants from China and India.

Explanation:

The European colonialism was spread out around much of the world. Southeast Asia too was conquered and colonized for certain period of time. The Europeans had big interest in this region because of its excellent strategic location, as well as because it was rich in multiple resources. Once the Europeans managed to gain full control over Southeast Asia they started to develop the port cities, which led to their rapid growth and became very attractive for the people to move in.

  • Lot of people saw the port cities as good places where they can find opportunities to prosper, so there was large scale migration toward them.
  • The migration toward the port cities was not just from the interior of the region, but also From other places, such as China and India.
  • While lot of people migrated in these places willingly, some were actually brought by the Europeans as labor force.
  • The number of Chinese and Indians was so large, that some areas became dominated by them, or in some regions they were the largest minority groups.
