Much of mandolin development revolved around the soundboard (the top). Pre-mandolin instruments were quiet instruments, strung with as many as six courses of gut strings, and were plucked with the fingers or with a quill. However, modern instruments are louderusing four courses of metal strings, which exert more pressure than the gut strings. The modern soundboard is designed to withstand the pressure of metal strings that would break earlier instruments. The soundboard comes in many shapesbut generally round or teardrop-shaped, sometimes with scrolls or other projections. There is usually one or more sound holes in the soundboard, either round, oval, or shaped like a calligraphic F (f-hole). A round or oval sound hole may be covered or bordered with decorative rosettes or purfling.
What did most of the development of the mandolin not revolve around?
A: unanswerable

As the School grew, more students were allowed to attend provided that they paid their own fees and lived in the town, outside the College's original buildings. These students became known as Oppidans, from the Latin word oppidum, meaning town. The Houses developed over time as a means of providing residence for the Oppidans in a more congenial manner, and during the 18th and 19th centuries were mostly run by women known as "dames". They typically contain about fifty boys. Although classes are organised on a School basis, most boys spend a large proportion of their time in their House. Each House has a formal name, mainly used for post and people outside the Eton community. It is generally known by the boys by the initials or surname of the House Master, the teacher who lives in the house and manages the pupils in it.
Oppidan residences were generally cared after by women known as what?
A: "dames"

Yazid died while the siege was still in progress, and the Umayyad army returned to Damascus, leaving Ibn al-Zubayr in control of Mecca. Yazid's son Muawiya II (68384) initially succeeded him but seems to have never been recognized as caliph outside of Syria. Two factions developed within Syria: the Confederation of Qays, who supported Ibn al-Zubayr, and the Quda'a, who supported Marwan, a descendant of Umayya via Wa'il ibn Umayyah. The partisans of Marwan triumphed at a battle at Marj Rahit, near Damascus, in 684, and Marwan became caliph shortly thereafter.
From whom was Marwan descended?
A: Umayya via Wa'il ibn Umayyah

Before the introduction of the brown tree snake, Guam was home to several endemic bird species. Among them were the Guam rail (or ko'ko' bird in Chamorro) and the Guam flycatcher, both common throughout the island. Today the flycatcher is entirely extinct while the Guam rail is extinct in the wild but bred in captivity by the Division of Aquatic and Wildlife Resources. The devastation caused by the snake has been significant over the past several decades. As many as twelve bird species are believed to have been driven to extinction. According to many elders, ko'ko' birds were common in Guam before World War II.
What is thought to have been the first bird species on Guam?
A:
unanswerable
