Problem: Please answer a question about the following article about Yale University:
Several explanations have been offered for Yale's representation in national elections since the end of the Vietnam War. Various sources note the spirit of campus activism that has existed at Yale since the 1960s, and the intellectual influence of Reverend William Sloane Coffin on many of the future candidates. Yale President Richard Levin attributes the run to Yale's focus on creating "a laboratory for future leaders," an institutional priority that began during the tenure of Yale Presidents Alfred Whitney Griswold and Kingman Brewster. Richard H. Brodhead, former dean of Yale College and now president of Duke University, stated: "We do give very significant attention to orientation to the community in our admissions, and there is a very strong tradition of volunteerism at Yale." Yale historian Gaddis Smith notes "an ethos of organized activity" at Yale during the 20th century that led John Kerry to lead the Yale Political Union's Liberal Party, George Pataki the Conservative Party, and Joseph Lieberman to manage the Yale Daily News. Camille Paglia points to a history of networking and elitism: "It has to do with a web of friendships and affiliations built up in school." CNN suggests that George W. Bush benefited from preferential admissions policies for the "son and grandson of alumni", and for a "member of a politically influential family." New York Times correspondent Elisabeth Bumiller and The Atlantic Monthly correspondent James Fallows credit the culture of community and cooperation that exists between students, faculty, and administration, which downplays self-interest and reinforces commitment to others.
Why did Richard Brodhead believe there were so many Yale alumni presidential candidates?
A: very strong tradition of volunteerism

However, from 1971 to 1975, NBA teams played preseason exhibitions against American Basketball Association teams. In the early days of the NBA, league clubs sometimes challenged the legendary barnstorming Harlem Globetrotters, with mixed success. The NBA has played preseason games in Europe and Asia. In the 2006 and 2007 seasons, the NBA and the primary European club competition, the Euroleague, conducted a preseason tournament featuring two NBA teams and the finalists from that year's Euroleague.[citation needed] In the 1998-99 and 2011-12 seasons, teams were limited to only two preseason games due to lockouts.

On what continents have NBA teams played preseason games outside the US?
Answer: Europe and Asia

Problem: Pesticides can be classified based upon their biological mechanism function or application method. Most pesticides work by poisoning pests. A systemic pesticide moves inside a plant following absorption by the plant. With insecticides and most fungicides, this movement is usually upward (through the xylem) and outward. Increased efficiency may be a result. Systemic insecticides, which poison pollen and nectar in the flowers[citation needed], may kill bees and other needed pollinators[citation needed].
What is the main way that peticides perform their function?
The answer is the following: by poisoning pests

In 1964, the biologists Paul Ehrlich and Holm pointed out cases where two or more clines are distributed discordantlyfor example, melanin is distributed in a decreasing pattern from the equator north and south; frequencies for the haplotype for beta-S hemoglobin, on the other hand, radiate out of specific geographical points in Africa. As the anthropologists Leonard Lieberman and Fatimah Linda Jackson observed, "Discordant patterns of heterogeneity falsify any description of a population as if it were genotypically or even phenotypically homogeneous".
To what profession do both Leonard Lieberman and Fatimah Linda Jackson belong?
anthropologists

Input: Wood
When a tree is very young it is covered with limbs almost, if not entirely, to the ground, but as it grows older some or all of them will eventually die and are either broken off or fall off. Subsequent growth of wood may completely conceal the stubs which will however remain as knots. No matter how smooth and clear a log is on the outside, it is more or less knotty near the middle. Consequently, the sapwood of an old tree, and particularly of a forest-grown tree, will be freer from knots than the inner heartwood. Since in most uses of wood, knots are defects that weaken the timber and interfere with its ease of working and other properties, it follows that a given piece of sapwood, because of its position in the tree, may well be stronger than a piece of heartwood from the same tree.

What hides the stubs of a tree's lost limbs from being visible later in its life?
Output: Subsequent growth

Problem: Please answer a question about the following article about Nanjing:
The city of Nanjing was razed after the Sui dynasty took over it. It renamed Shengzhou () in Tang dynasty and resuscitated during the late Tang. It was chosen as the capital and called Jinling () during the Southern Tang (937976), a state that succeeded Wu state. It renamed Jiangning () in Northern Song dynasty and renamed Jiankang in Southern Song dynasty. Jiankang's textile industry burgeoned and thrived during the Song dynasty despite the constant threat of foreign invasions from the north by the Jurchen-led Jin dynasty. The court of Da Chu, a short-lived puppet state established by the Jurchens, and the court of Song were once in the city. Song was eventually exterminated by the Mongol empire under the name Yuan and in Yuan dynasty the city's status as a hub of the textile industry was further consolidated.
During what dynasty did Nanjing become a thriving textile city?
A:
the Song dynasty
