Problem: Israel:

The sovereign territory of Israel (according to the demarcation lines of the 1949 Armistice Agreements and excluding all territories captured by Israel during the 1967 Six-Day War) is approximately 20,770 square kilometers (8,019 sq mi) in area, of which two percent is water. However Israel is so narrow that the exclusive economic zone in the Mediterranean is double the land area of the country. The total area under Israeli law, including East Jerusalem and the Golan Heights, is 22,072 square kilometers (8,522 sq mi), and the total area under Israeli control, including the military-controlled and partially Palestinian-governed territory of the West Bank, is 27,799 square kilometers (10,733 sq mi). Despite its small size, Israel is home to a variety of geographic features, from the Negev desert in the south to the inland fertile Jezreel Valley, mountain ranges of the Galilee, Carmel and toward the Golan in the north. The Israeli Coastal Plain on the shores of the Mediterranean is home to 57 percent of the nation's population. East of the central highlands lies the Jordan Rift Valley, which forms a small part of the 6,500-kilometer (4,039 mi) Great Rift Valley.

What's home to 57% of the nation's population?

A: Israeli Coastal Plain

Problem: At extremely large airports, a circuit is in place but not usually used. Rather, aircraft (usually only commercial with long routes) request approach clearance while they are still hours away from the airport, often before they even take off from their departure point. Large airports have a frequency called Clearance Delivery which is used by departing aircraft specifically for this purpose. This then allows aircraft to take the most direct approach path to the runway and land without worrying about interference from other aircraft. While this system keeps the airspace free and is simpler for pilots, it requires detailed knowledge of how aircraft are planning to use the airport ahead of time and is therefore only possible with large commercial airliners on pre-scheduled flights. The system has recently become so advanced that controllers can predict whether an aircraft will be delayed on landing before it even takes off; that aircraft can then be delayed on the ground, rather than wasting expensive fuel waiting in the air.
What is the frequency called that is used by departing aircraft for the purpose of requesting approach clearance?

Answer: Clearance Delivery

Context and question: Under modern constitutional conventions, the sovereign acts on the advice of his or her ministers. Since these ministers most often maintain the support of parliament and are the ones who obtain the passage of bills, it is highly improbable that they would advise the sovereign to withhold assent. An exception is sometimes stated to be if bills are not passed in good faith, though it is difficult to make an interpretation on what this circumstance might constitute. Hence, in modern practice, royal assent is always granted; a refusal to do so would be appropriate only in an emergency requiring the use of the monarch's reserve powers.
Whose advice does a sovereign follow?
Answer: his or her ministers
