The correct answer to this open question is the following.
Although the question is incomplete because it does not provide any map for reference, we can say that the Tigris River and the Euphrates River are found in the Middle East region, in what today is Bagdad, Iraq. The mountains close to this Tigris-Euphrates River System are called the Taurus Mountains. The Tigris River starts in Turkey, crosses Iraq, and ends in the Persian Gulf. The Euphrates River also starts in Turkey, crosses Syria, then Iraq, and joins the Tigris River before ending in the Persian Gulf. These two rivers are very symbolic in the history of humanity because the Sumerians settled in the middle of both rivers. They are considered by historians as the oldest civilization of planet Earth.
They grew crops to sale and contributed to the nation economic development. <span />
An NGO is a non-governmental organization. They are voluntary groups, which are independent of governments. Some do get funding from government programs, but they are not under the direct control of a government office. NGOs typically also are not-for-profit; they are not businesses aimed at making money for themselves. Their aim is to help people in disadvantaged areas or circumstances. Some NGOs give out loans to help people improve their lives. Typically they will have more flexible or workable loan arrangements for a needy borrower than might be available from typical governmental sources of loans or traditional bank loans. For instance, there are NGOs that will grant small business loans without requiring collateral. Or there are NGOs that do microlending -- very small loans in developing countries to help someone get started with a very basic business. FINCA and Hope International are both examples of NGOs that do this sort of microlending.
Coral reef destruction is caused of course by climate change, responsible for our warmer oceans. Corals cannot survive if the water temperature is too high. Higher water temperatures is the main reason behind the death of nearly half of the Great Barrier Reef’s corals.
Urban and industrial waste and oil pollution from shipping are poisoning reefs too – some pollutants, such as sewage and runoff from farming increase the level of nitrogen in seawater, causing an overgrowth of algae, which smothers reefs by cutting off their sunlight.
So A, B and C are the correct answers
