[EX Q]: Although the existence of dictionaries and encyclopedias spanned into ancient times, the texts changed from simply defining words in a long running list to far more detailed discussions of those words in 18th-century encyclopedic dictionaries. The works were part of an Enlightenment movement to systematize knowledge and provide education to a wider audience than the elite. As the 18th century progressed, the content of encyclopedias also changed according to readers' tastes. Volumes tended to focus more strongly on secular affairs, particularly science and technology, rather than matters of theology.
[EX A]: How did dictionaries and encyclopedias change in the 18th century?

[EX Q]: Most light bulbs have either clear or coated glass. The coated glass bulbs have a white powdery substance on the inside called kaolin. Kaolin, or kaolinite, is a white, chalky clay in a very fine powder form, that is blown in and electrostatically deposited on the interior of the bulb. It diffuses the light emitted from the filament, producing a more gentle and evenly distributed light. Manufacturers may add pigments to the kaolin to adjust the characteristics of the final light emitted from the bulb. Kaolin diffused bulbs are used extensively in interior lighting because of their comparatively gentle light. Other kinds of colored bulbs are also made, including the various colors used for "party bulbs", Christmas tree lights and other decorative lighting. These are created by coloring the glass with a dopant; which is often a metal like cobalt (blue) or chromium (green). Neodymium-containing glass is sometimes used to provide a more natural-appearing light.
[EX A]: What is the powdery substance in coated glass light bulbs?

[EX Q]: Following his defeat in the civil war, Gaddafi's system of governance was dismantled and replaced under the interim government of the NTC, who legalised trade unions and freedom of the press. In July 2012, elections were held to form a new General National Congress (GNC), who officially took over governance from the NTC in August. The GNC proceeded to elect Mohammed Magariaf as president of the chamber, and then voted Mustafa A.G. Abushagur as Prime Minister; when Abushagar failed to gain congressional approval, the GNC instead elected Ali Zeidan to the position. In January 2013, the GNC officially renamed the Jamahiriyah as the "State of Libya".
[EX A]:
Who was elected president of the GNC?
