Problem: Often taxonomists prefer to use phylogenetic analysis to determine whether a population can be considered a subspecies. Phylogenetic analysis relies on the concept of derived characteristics that are not shared between groups, usually applying to populations that are allopatric (geographically separated) and therefore discretely bounded. This would make a subspecies, evolutionarily speaking, a clade – a group with a common evolutionary ancestor population. The smooth gradation of human genetic variation in general tends to rule out any idea that human population groups can be considered monophyletic (cleanly divided), as there appears to always have been considerable gene flow between human populations. Rachel Caspari (2003) have argued that clades are by definition monophyletic groups (a taxon that includes all descendants of a given ancestor) and since no groups currently regarded as races are monophyletic, none of those groups can be clades.
Who argued in 2003 that all clades are by definition monophyletic groups?
The answer is the following: Rachel Caspari


The international repertoire of music for mandolin is almost unlimited, and musicians use it to play various types of music. This is especially true of violin music, since the mandolin has the same tuning of the violin. Following its invention and early development in Italy the mandolin spread throughout the European continent. The instrument was primarily used in a classical tradition with Mandolin orchestras, so called Estudiantinas or in Germany Zupforchestern appearing in many cities. Following this continental popularity of the mandolin family local traditions appeared outside of Europe in the Americas and in Japan. Travelling mandolin virtuosi like Giuseppe Pettine, Raffaele Calace and Silvio Ranieri contributed to the mandolin becoming a "fad" instrument in the early 20th century. This "mandolin craze" was fading by the 1930s, but just as this practice was falling into disuse, the mandolin found a new niche in American country, old-time music, bluegrass and folk music. More recently, the Baroque and Classical mandolin repertory and styles have benefited from the raised awareness of and interest in Early music, with media attention to classical players such as Israeli Avi Avital, Italian Carlo Aonzo and American Joseph Brent.
When did the mandolin craze end?
1930s


Input: North Carolina
Most of the English colonists had arrived as indentured servants, hiring themselves out as laborers for a fixed period to pay for their passage. In the early years the line between indentured servants and African slaves or laborers was fluid. Some Africans were allowed to earn their freedom before slavery became a lifelong status. Most of the free colored families formed in North Carolina before the Revolution were descended from unions or marriages between free white women and enslaved or free African or African-American men. Because the mothers were free, their children were born free. Many had migrated or were descendants of migrants from colonial Virginia. As the flow of indentured laborers to the colony decreased with improving economic conditions in Great Britain, planters imported more slaves, and the state's legal delineations between free and slave status tightened, effectively hardening the latter into a racial caste. The economy's growth and prosperity was based on slave labor, devoted first to the production of tobacco.

Most English colonists arrived as what?
Output: indentured servants


Input: Article: The site selected for the university was a hill known as Mount Oread, which was owned by former Kansas Governor Charles L. Robinson. Robinson and his wife Sara bestowed the 40-acre (16 ha) site to the State of Kansas in exchange for land elsewhere. The philanthropist Amos Adams Lawrence donated $10,000 of the necessary endowment fund, and the citizens of Lawrence raised the remaining cash by issuing notes backed by Governor Carney. On November 2, 1863, Governor Carney announced that Lawrence had met the conditions to get the state university, and the following year the university was officially organized. The school's Board of Regents held its first meeting in March 1865, which is the event that KU dates its founding from. Work on the first college building began later that year. The university opened for classes on September 12, 1866, and the first class graduated in 1873.

Now answer this question: Who did the site of KU's construction originally belong to?

Output: Charles L. Robinson


Article: In 1185 John made his first visit to Ireland, accompanied by 300 knights and a team of administrators. Henry had tried to have John officially proclaimed King of Ireland, but Pope Lucius III would not agree. John's first period of rule in Ireland was not a success. Ireland had only recently been conquered by Anglo-Norman forces, and tensions were still rife between Henry II, the new settlers and the existing inhabitants. John infamously offended the local Irish rulers by making fun of their unfashionable long beards, failed to make allies amongst the Anglo-Norman settlers, began to lose ground militarily against the Irish and finally returned to England later in the year, blaming the viceroy, Hugh de Lacy, for the fiasco.

Question: How many knights accompanied John to Ireland?
Ans: 300


Input: Infrared
In the semiconductor industry, infrared light can be used to characterize materials such as thin films and periodic trench structures. By measuring the reflectance of light from the surface of a semiconductor wafer, the index of refraction (n) and the extinction Coefficient (k) can be determined via the Forouhi-Bloomer dispersion equations. The reflectance from the infrared light can also be used to determine the critical dimension, depth, and sidewall angle of high aspect ratio trench structures.

What letter represents the index of refraction?
Output:
n
