Farmers have found ways to grow major crops in dry soil. Flooding and water pollution are driving people out of areas near water. Better technology allows easier access to water supplies. Human beings have adapted to living with little water.

Answer 1

Of these options, "Better technology allows easier access to water supplies" is the best answer. Things like canals and waterways greatly increase the number of people who are able to live and farm on dryer land.

Answer 2

The correct answer is - Better technology allows easier access to water supplies.

The advancements in the technology have made it possible for people to live in most of the places on the Earth if they want to. The transportation of goods, manufacturing goods, production of goods, have all reached new heights, which enable the life to be possible even in the middle of the arid or semi-arid regions.

The biggest problem in regions like this is usually the lack of water resources. But with the modern technology, water can be brought to the place through pipelines from hundreds of miles away, it can be transported with the modern vehicles in the form of bottled water, or if there's salty water in close proximity it can be freed from the salt and made suitable for drinking.
