The problem: Answer a question about this article:
Hydrogen production technologies been a significant area of solar chemical research since the 1970s. Aside from electrolysis driven by photovoltaic or photochemical cells, several thermochemical processes have also been explored. One such route uses concentrators to split water into oxygen and hydrogen at high temperatures (2,300–2,600 °C or 4,200–4,700 °F). Another approach uses the heat from solar concentrators to drive the steam reformation of natural gas thereby increasing the overall hydrogen yield compared to conventional reforming methods. Thermochemical cycles characterized by the decomposition and regeneration of reactants present another avenue for hydrogen production. The Solzinc process under development at the Weizmann Institute uses a 1 MW solar furnace to decompose zinc oxide (ZnO) at temperatures above 1,200 °C (2,200 °F). This initial reaction produces pure zinc, which can subsequently be reacted with water to produce hydrogen.
What is the name of the process being developed by the Weizmann Institute?
****
The answer: Solzinc process


Problem: Please answer a question about the following article about BeiDou Navigation Satellite System:
In December 2011, the system went into operation on a trial basis. It has started providing navigation, positioning and timing data to China and the neighbouring area for free from 27 December. During this trial run, Compass will offer positioning accuracy to within 25 meters, but the precision will improve as more satellites are launched. Upon the system's official launch, it pledged to offer general users positioning information accurate to the nearest 10 m, measure speeds within 0.2 m per second, and provide signals for clock synchronisation accurate to 0.02 microseconds.
Upon launching, the Compass system, what was the speed promised to users?
A: within 0.2 m per second


Question: Read this and answer the question

The immediate cause of the riots is unclear, with many commentators citing the killing of ten Burmese Muslims by ethnic Rakhine after the rape and murder of a Rakhine woman as the main cause. Whole villages have been "decimated". Over 300 houses and a number of public buildings have been razed. According to Tun Khin, the president of the Burmese Rohingya Organisation UK (BROUK), as of 28 June 2012, 650 Rohingyas have been killed, 1,200 are missing, and more than 80,000 have been displaced. According to the Myanmar authorities, the violence, between ethnic Rakhine Buddhists and Rohingya Muslims, left 78 people dead, 87 injured, and thousands of homes destroyed. It displaced more than 52,000 people.

Who is the president of the BROUK's UK division?
Answer: Tun Khin


Problem: After Charles II of England (1630–1685) was restored to the English throne in 1660 following Oliver Cromwell's Protectorate, he granted the chartered Province of Carolina to eight of his loyal friends, known as the Lords Proprietors, on March 24, 1663. It took seven years before the group arranged for settlement expeditions. The first of these founded Charles Town, in 1670. Governance, settlement, and development were to follow a visionary plan known as the Grand Model prepared for the Lords Proprietors by John Locke.
What year was Charles Town founded?
The answer is the following: 1670


Sandra Laing is a South African woman who was classified as Coloured by authorities during the apartheid era, due to her skin colour and hair texture, although her parents could prove at least three generations of European ancestors. At age 10, she was expelled from her all-white school. The officials' decisions based on her anomalous appearance disrupted her family and adult life. She was the subject of the 2008 biographical dramatic film Skin, which won numerous awards.
At was age was Sandra Laing expelled from school?
age 10


Here is a question about this article: The Croatian Latin alphabet (Gajica) followed suit shortly afterwards, when Ljudevit Gaj defined it as standard Latin with five extra letters that had diacritics, apparently borrowing much from Czech, but also from Polish, and inventing the unique digraphs "lj", "nj" and "dž". These digraphs are represented as "ļ, ń and ǵ" respectively in the "Rječnik hrvatskog ili srpskog jezika", published by the former Yugoslav Academy of Sciences and Arts in Zagreb. The latter digraphs, however, are unused in the literary standard of the language. All in all, this makes Serbo-Croatian the only Slavic language to officially use both the Latin and Cyrillic scripts, albeit the Latin version is more commonly used.
What is the answer to this question: How many extra letters does the Croatian Latin alphabet have?
****
So...
five
