Input: Article: Multi-color LEDs offer not merely another means to form white light but a new means to form light of different colors. Most perceivable colors can be formed by mixing different amounts of three primary colors. This allows precise dynamic color control. As more effort is devoted to investigating this method, multi-color LEDs should have profound influence on the fundamental method that we use to produce and control light color. However, before this type of LED can play a role on the market, several technical problems must be solved. These include that this type of LED's emission power decays exponentially with rising temperature, resulting in a substantial change in color stability. Such problems inhibit and may preclude industrial use. Thus, many new package designs aimed at solving this problem have been proposed and their results are now being reproduced by researchers and scientists.

Now answer this question: What problem results when rising temperatures decays power?

Output: substantial change in color stability


Article: Public expenditure of the GDP was less in 2002–05 than in 1991. Public education is theoretically free and mandatory for under-16-year-olds, but in practice, expenses exist. Net primary enrollment rate was 44% in 2005, much less than the 79% in 1991. The country has universities. Education between ages six and sixteen is compulsory. Pupils who complete six years of primary school and seven years of secondary school obtain a baccalaureate. At the university, students can obtain a bachelor's degree in three years and a master's after four. Marien Ngouabi University—which offers courses in medicine, law and several other fields—is the country's only public university. Instruction at all levels is in French, and the educational system as a whole models the French system. The educational infrastructure has been seriously degraded as a result of political and economic crises. There are no seats in most classrooms, forcing children to sit on the floor. Enterprising individuals have set up private schools, but they often lack the technical knowledge and familiarity with the national curriculum to teach effectively. Families frequently enroll their children in private schools only to find they cannot make the payments.

Question: What was the school enrollment rate in 2005?
Ans: 44%


Here is a question about this article: Nintendo also made two turbo controllers for the NES called NES Advantage and the NES Max. Both controllers had a Turbo feature, a feature where one tap of the button represented multiple taps. This feature allowed players to shoot much faster during shooter games. The NES Advantage had two knobs that adjusted the firing rate of the turbo button from quick to Turbo, as well as a "Slow" button that slowed down the game by rapidly pausing the game. The "Slow" button did not work with games that had a pause menu or pause screen and can interfere with jumping and shooting. The NES Max also had the Turbo Feature, but it was not adjustable, in contrast with the Advantage. It also did not have the "Slow" button. Its wing-like shape made it easier to hold than the Advantage and it also improved on the joystick. Turbo features were also featured on the NES Satellite, the NES Four Score, and the U-Force. Other accessories include the Power Pad and the Power Glove, which was featured in the movie The Wizard.
What is the answer to this question: The NES Max also did not feature what?
****
So... "Slow" button


The problem: Answer a question about this article:
An earthquake emergency relief team of 184 people (consisting of 12 people from the State Seismological Bureau, 150 from the Beijing Military Area Command, and 22 from the Armed Police General Hospital) left Beijing from Nanyuan Airport late May 12 in two military transport planes to travel to Wenchuan County.
How many of the team were from the police?
****
The answer: 22


Problem: Please answer a question about the following article about Royal Institute of British Architects:
The RIBA Guide to its Archive and History (1986) has a section on the "Statutory registration of architects" with a bibliography extending from a draft bill of 1887 to one of 1969. The Guide's section on "Education" records the setting up in 1904 of the RIBA Board of Architectural Education, and the system by which any school which applied for recognition, whose syllabus was approved by the Board and whose examinations were conducted by an approved external examiner, and whose standard of attainment was guaranteed by periodical inspections by a "Visiting Board" from the BAE, could be placed on the list of "recognized schools" and its successful students could qualify for exemption from RIBA examinations.
What was necessary for testing in schools applying to the RIBA Board?
A: an approved external examiner


Question: Read this and answer the question

Inns are buildings where travellers can seek lodging and, usually, food and drink. They are typically located in the country or along a highway. In Europe, they possibly first sprang up when the Romans built a system of roads two millennia ago.[citation needed] Some inns in Europe are several centuries old. In addition to providing for the needs of travellers, inns traditionally acted as community gathering places.

How many thousand years ago did the Romans build their road system?
Answer:
two
