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.

Question: What problem results when rising temperatures decays power?
Ans: substantial change in color stability


Article: The area north of the Congo River came under French sovereignty in 1880 as a result of Pierre de Brazza's treaty with Makoko of the Bateke. This Congo Colony became known first as French Congo, then as Middle Congo in 1903. In 1908, France organized French Equatorial Africa (AEF), comprising Middle Congo, Gabon, Chad, and Oubangui-Chari (the modern Central African Republic). The French designated Brazzaville as the federal capital. Economic development during the first 50 years of colonial rule in Congo centered on natural-resource extraction. The methods were often brutal: construction of the Congo–Ocean Railroad following World War I has been estimated to have cost at least 14,000 lives.

Question: Who brokered a traty with the Makoko people?
Ans: Pierre de Brazza


Article: Great Britain lost Minorca in the Mediterranean to the French in 1756 but captured the French colonies in Senegal in 1758. The British Royal Navy took the French sugar colonies of Guadeloupe in 1759 and Martinique in 1762 as well as the Spanish cities of Havana in Cuba, and Manila in the Philippines, both prominent Spanish colonial cities. However, expansion into the hinterlands of both cities met with stiff resistance. In the Philippines, the British were confined to Manila until their agreed upon withdrawal at the war's end.

Question: What island did Great Britain lose in 1756?
Ans: Great Britain lost Minorca in the Mediterranean to the French in 1756


Article: A typical traditional Eritrean dish consists of injera accompanied by a spicy stew, which frequently includes beef, kid, lamb or fish. Overall, Eritrean cuisine strongly resembles those of neighboring Ethiopia, Eritrean cooking tend to feature more seafood than Ethiopian cuisine on account of their coastal location. Eritrean dishes are also frequently "lighter" in texture than Ethiopian meals. They likewise tend to employ less seasoned butter and spices and more tomatoes, as in the tsebhi dorho delicacy.

Question: What meat does a traditional Eritrean stew consist of?
Ans:
beef, kid, lamb or fish
