Problem: In a response to Livingstone, Theodore Dobzhansky argued that when talking about race one must be attentive to how the term is being used: "I agree with Dr. Livingstone that if races have to be 'discrete units,' then there are no races, and if 'race' is used as an 'explanation' of the human variability, rather than vice versa, then the explanation is invalid." He further argued that one could use the term race if one distinguished between "race differences" and "the race concept." The former refers to any distinction in gene frequencies between populations; the latter is "a matter of judgment." He further observed that even when there is clinal variation, "Race differences are objectively ascertainable biological phenomena but it does not follow that racially distinct populations must be given racial (or subspecific) labels." In short, Livingstone and Dobzhansky agree that there are genetic differences among human beings; they also agree that the use of the race concept to classify people, and how the race concept is used, is a matter of social convention. They differ on whether the race concept remains a meaningful and useful social convention.
On what point did Dobzhansky agree with Dr. Livingstone?
The answer is the following: if races have to be 'discrete units,' then there are no races

Problem: Public expenditure health was at 8.9% of the GDP in 2004, whereas private expenditure was at 1.3%. As of 2012, the HIV/AIDS prevalence was at 2.8% among 15- to 49-year-olds. Health expenditure was at US$30 per capita in 2004. A large proportion of the population is undernourished, with malnutrition being a problem in Congo-Brazzaville. There were 20 physicians per 100,000 persons in the early 2000s (decade).
How much was spent per capita on health in 2004 as measured in US dollars?
The answer is the following: $30

Problem: The Frankish kingdom in northern Gaul split into kingdoms called Austrasia, Neustria, and Burgundy during the 6th and 7th centuries, all of them ruled by the Merovingian dynasty, who were descended from Clovis. The 7th century was a tumultuous period of wars between Austrasia and Neustria. Such warfare was exploited by Pippin (d. 640), the Mayor of the Palace for Austrasia who became the power behind the Austrasian throne. Later members of his family inherited the office, acting as advisers and regents. One of his descendants, Charles Martel (d. 741), won the Battle of Poitiers in 732, halting the advance of Muslim armies across the Pyrenees.[K] Great Britain was divided into small states dominated by the kingdoms of Northumbria, Mercia, Wessex, and East Anglia, which were descended from the Anglo-Saxon invaders. Smaller kingdoms in present-day Wales and Scotland were still under the control of the native Britons and Picts. Ireland was divided into even smaller political units, usually known as tribal kingdoms, under the control of kings. There were perhaps as many as 150 local kings in Ireland, of varying importance.
Along with Austrasia and Neustria, what kingdom was originally part of the Frankish kingdom?
The answer is the following: Burgundy

Problem: The monastic communities of the Judean Desert also decorated their monasteries with mosaic floors. The Monastery of Martyrius was founded in the end of the 5th century and it was re-discovered in 198285. The most important work of art here is the intact geometric mosaic floor of the refectory although the severely damaged church floor was similarly rich. The mosaics in the church of the nearby Monastery of Euthymius are of later date (discovered in 1930). They were laid down in the Umayyad era, after a devastating earthquake in 659. Two six pointed stars and a red chalice are the most important surviving features.
When was the Monastery of Martyrius created?
The answer is the following:
the end of the 5th century
