Input: Article: The data indicate that the individual was from a population directly ancestral to present South American and Central American Native American populations, and closely related to present North American Native American populations. The implication is that there was an early divergence between North American and Central American plus South American populations. Hypotheses which posit that invasions subsequent to the Clovis culture overwhelmed or assimilated previous migrants into the Americas were ruled out.

Now answer this question: What type of divergence is implicated to have occurred between North American and South American populations?

Output: early


Article: The character of the seed coat bears a definite relation to that of the fruit. They protect the embryo and aid in dissemination; they may also directly promote germination. Among plants with indehiscent fruits, in general, the fruit provides protection for the embryo and secures dissemination. In this case, the seed coat is only slightly developed. If the fruit is dehiscent and the seed is exposed, in general, the seed-coat is well developed, and must discharge the functions otherwise executed by the fruit.

Question: What does the seed coat protect?
Ans: embryo


Here is a question about this article: The last great period of Roman mosaic art was the 12th–13th century when Rome developed its own distinctive artistic style, free from the strict rules of eastern tradition and with a more realistic portrayal of figures in the space. Well-known works of this period are the floral mosaics of the Basilica di San Clemente, the façade of Santa Maria in Trastevere and San Paolo fuori le Mura. The beautiful apse mosaic of Santa Maria in Trastevere (1140) depicts Christ and Mary sitting next to each other on the heavenly throne, the first example of this iconographic scheme. A similar mosaic, the Coronation of the Virgin, decorates the apse of Santa Maria Maggiore. It is a work of Jacopo Torriti from 1295. The mosaics of Torriti and Jacopo da Camerino in the apse of San Giovanni in Laterano from 1288–94 were thoroughly restored in 1884. The apse mosaic of San Crisogono is attributed to Pietro Cavallini, the greatest Roman painter of the 13th century. Six scenes from the life of Mary in Santa Maria in Trastevere were also executed by Cavallini in 1290. These mosaics are praised for their realistic portrayal and attempts of perspective. There is an interesting mosaic medaillon from 1210 above the gate of the church of San Tommaso in Formis showing Christ enthroned between a white and a black slave. The church belonged to the Order of the Trinitarians which was devoted to ransoming Christian slaves.
What is the answer to this question: When was the last period of Roman mosaic art?
****
So... the 12th–13th century


The problem: Answer a question about this article:
Neptune is not visible to the unaided eye and is the only planet in the Solar System found by mathematical prediction rather than by empirical observation. Unexpected changes in the orbit of Uranus led Alexis Bouvard to deduce that its orbit was subject to gravitational perturbation by an unknown planet. Neptune was subsequently observed with a telescope on 23 September 1846 by Johann Galle within a degree of the position predicted by Urbain Le Verrier. Its largest moon, Triton, was discovered shortly thereafter, though none of the planet's remaining known 14 moons were located telescopically until the 20th century. The planet's distance from Earth gives it a very small apparent size, making it challenging to study with Earth-based telescopes. Neptune was visited by Voyager 2, when it flew by the planet on 25 August 1989. The advent of Hubble Space Telescope and large ground-based telescopes with adaptive optics has recently allowed for additional detailed observations from afar.
What is Neptune's largest moon? 
****
The answer: Triton


Problem: Please answer a question about the following article about Political party:
When they lost power, the old Whig leadership dissolved into a decade of factional chaos with distinct "Grenvillite", "Bedfordite", "Rockinghamite", and "Chathamite" factions successively in power, and all referring to themselves as "Whigs". Out of this chaos, the first distinctive parties emerged. The first such party was the Rockingham Whigs under the leadership of Charles Watson-Wentworth and the intellectual guidance of the political philosopher Edmund Burke. Burke laid out a philosophy that described the basic framework of the political party as "a body of men united for promoting by their joint endeavours the national interest, upon some particular principle in which they are all agreed". As opposed to the instability of the earlier factions, which were often tied to a particular leader and could disintegrate if removed from power, the party was centred around a set of core principles and remained out of power as a united opposition to government.
Who was the leader of the Rockingham Whigs?
A: Charles Watson-Wentworth

On 9 February 2014, Swiss voters narrowly approved by 50.3% a ballot initiative launched by the national conservative Swiss People's Party (SVP/UDC) to restrict immigration, and thus reintroducing a quota system on the influx of foreigners. This initiative was mostly backed by rural (57.6% approvals), suburban (51.2% approvals), and isolated cities (51.3% approvals) of Switzerland as well as by a strong majority (69.2% approval) in the canton of Ticino, while metropolitan centres (58.5% rejection) and the French-speaking part (58.5% rejection) of Switzerland rather rejected it. Some news commentators claim that this proposal de facto contradicts the bilateral agreements on the free movement of persons from these respective countries.

Which centres of Switzerland mostly rejected the quota system for foreigners?
Answer:
metropolitan
