QUES: The convention in the English language is to call nearly all national heads of government "prime minister" (sometimes modified to the equivalent term of premier), regardless of the correct title of the head of government as applied in his or her respective country. The few exceptions to the rule are Germany and Austria, whose heads of government titles are almost always translated as Chancellor; Monaco, whose head of government is referred to as the Minister of State; and Vatican City, for which the head of government is titled the Secretary of State. In the case of Ireland, the head of government is occasionally referred to as the Taoiseach by English speakers. A stand-out case is the President of Iran, who is not actually a head of state, but the head of the government of Iran. He is referred to as "president" in both the Persian and English languages.

The modern English word green comes from the Middle English and Anglo-Saxon word grene, from the same Germanic root as the words "grass" and "grow". It is the color of living grass and leaves and as a result is the color most associated with springtime, growth and nature. By far the largest contributor to green in nature is chlorophyll, the chemical by which plants photosynthesize and convert sunlight into chemical energy. Many creatures have adapted to their green environments by taking on a green hue themselves as camouflage. Several minerals have a green color, including the emerald, which is colored green by its chromium content.

Problem: In 1983 fighting between Palestinian refugees and Lebanese factions reignited that nation's long-running civil war. A UN agreement brought an international force of peacekeepers to occupy Beirut and guarantee security. US Marines landed in August 1982 along with Italian and French forces. On October 23, 1983, a suicide bomber driving a truck filled with 6 tons of TNT crashed through a fence and destroyed the Marine barracks, killing 241 Marines; seconds later, a second bomber leveled a French barracks, killing 58. Subsequently the US Navy engaged in bombing of militia positions inside Lebanon.
