14) Waldo is in the West Bank. The West Bank is predominately Arab, but Israel has been building Jewish settlements there.
15) Waldo is in Turkey. The Tigris and Euphrates Rivers empty into Turkey, Iraq, and Syria. However, since Iraq and Syria aren't among the answer choices, it's Turkey.
16) Turkey built the dams.
17) Jordan has a water shortage and it's north of Saudi Arabia.
20) Waldo is talking to Kurds. Syria and Turkey have large Kurdish populations. In fact, Kurds make up 18% of the population in Turkey.
Hope this helps.
