Problem: New York City:

Under the Köppen climate classification, using the 0 °C (32 °F) coldest month (January) isotherm, New York City itself experiences a humid subtropical climate (Cfa) and is thus the northernmost major city on the North American continent with this categorization. The suburbs to the immediate north and west lie in the transition zone from a humid subtropical (Cfa) to a humid continental climate (Dfa). The area averages 234 days with at least some sunshine annually, and averages 57% of possible sunshine annually, accumulating 2,535 hours of sunshine per annum. The city falls under USDA 7b Plant Hardiness zone.

What type of climate does NYC possess?
---
A: humid subtropical


Problem: Some historians estimate the number of magnates as 1% of the number of szlachta. Out of approx. one million szlachta, tens of thousands of families, only 200–300 persons could be classed as great magnates with country-wide possessions and influence, and 30–40 of them could be viewed as those with significant impact on Poland's politics.
Historians estimate how much of magnates make up szlachta?
---
Answer: 1%


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
One of the first quantum effects to be explicitly noticed (but not understood at the time) was a Maxwell observation involving hydrogen, half a century before full quantum mechanical theory arrived. Maxwell observed that the specific heat capacity of H2 unaccountably departs from that of a diatomic gas below room temperature and begins to increasingly resemble that of a monatomic gas at cryogenic temperatures. According to quantum theory, this behavior arises from the spacing of the (quantized) rotational energy levels, which are particularly wide-spaced in H2 because of its low mass. These widely spaced levels inhibit equal partition of heat energy into rotational motion in hydrogen at low temperatures. Diatomic gases composed of heavier atoms do not have such widely spaced levels and do not exhibit the same effect.
Who observed the specific heat capacity of H2?
A: Maxwell


Context and question: Agrobacterium tumefaciens, a soil rhizosphere bacterium, can attach to plant cells and infect them with a callus-inducing Ti plasmid by horizontal gene transfer, causing a callus infection called crown gall disease. Schell and Van Montagu (1977) hypothesised that the Ti plasmid could be a natural vector for introducing the Nif gene responsible for nitrogen fixation in the root nodules of legumes and other plant species. Today, genetic modification of the Ti plasmid is one of the main techniques for introduction of transgenes to plants and the creation of genetically modified crops.
Who developed the procedures used in this transfer?
Answer: Schell and Van Montagu


Question: Chinese officials canceled the torch relay ceremony amidst disruptions, including a Tibetan flag flown from a window in the City Hall by Green Party officials. The third torchbearer in the Paris leg, Jin Jing, who was disabled and carried the torch on a wheelchair, was assaulted several times by unidentified protestors seemingly from the pro-Tibet independent camp. In interviews, Jin Jing said that she was "tugged at, scratched" and "kicked", but that she "did not feel the pain at the time." She received praise from ethnic Chinese worldwide as "Angel in Wheelchair". The Chinese government gave the comment that "the Chinese respect France a lot" but "Paris [has slapped] its own face."
Is there an answer to this question: Who threw a a Tibetan flag from a City Hall window?

Answer: Green Party officials.


Question: In 1238, King James I of Aragon, with an army composed of Aragonese, Catalans, Navarrese and crusaders from the Order of Calatrava, laid siege to Valencia and on 28 September obtained a surrender. Fifty thousand Moors were forced to leave. Poets such as Ibn al-Abbar and Ibn Amira mourned this exile from their beloved Valencia. After the Christian victory and the expulsion of the Muslim population the city was divided between those who had participated in the conquest, according to the testimony in the Llibre del Repartiment (Book of Distribution). James I granted the city new charters of law, the Furs of Valencia, which later were extended to the whole kingdom of Valencia. Thenceforth the city entered a new historical stage in which a new society and a new language developed, forming the basis of the character of the Valencian people as they are known today.
Is there an answer to this question: What ruler attacked Valencia in 1238?

Answer:
King James I of Aragon
