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.
What is merely "a matter of judgement"?
The answer is the following: "the race concept."

Problem: The Czech dialects spoken in Moravia and Silesia are known as Moravian (moravština). In the Austro-Hungarian Empire, "Bohemian-Moravian-Slovak" was a language citizens could register as speaking (with German, Polish and several others). Of the Czech dialects, only Moravian is distinguished in nationwide surveys by the Czech Statistical Office. As of 2011, 62,908 Czech citizens spoke Moravian as their first language and 45,561 were diglossal (speaking Moravian and standard Czech as first languages).
How many Czechs spoke Moravian as their first language as of 2011?
The answer is the following: 62,908

Problem: The first recorded use of the term (or its cognates in other languages) is in the New Testament, in Acts 11:26, after Barnabas brought Saul (Paul) to Antioch where they taught the disciples for about a year, the text says: "[...] the disciples were called Christians first in Antioch." The second mention of the term follows in Acts 26:28, where Herod Agrippa II replied to Paul the Apostle, "Then Agrippa said unto Paul, Almost thou persuadest me to be a Christian." The third and final New Testament reference to the term is in 1 Peter 4:16, which exhorts believers: "Yet if [any man suffer] as a Christian, let him not be ashamed; but let him glorify God on this behalf."
Who made the second reference to the word Christian in the Bible?
The answer is the following: Herod Agrippa II

Problem: During the Risorgimento, proponents of Italian republicanism and Italian nationalism, such as Alessandro Manzoni, stressed the importance of establishing a uniform national language in order to better create an Italian national identity. With the unification of Italy in the 1860s, standard Italian became the official national language of the new Italian state, while the various unofficial regional languages of Italy gradually became regarded as subordinate "dialects" to Italian, increasingly associated negatively with lack of education or provincialism. However, at the time of the Italian Unification, standard Italian still existed mainly as a literary language, and only 2.5% of Italy's population could speak standard Italian.
What Italian nationalist spoke of the importance of a national Italian language?
The answer is the following:
Alessandro Manzoni
