Problem: Incandescent light bulb:

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.

What is the effect of a kaolin coating on the light cast?
---
A: a more gentle and evenly distributed light

Problem: Qur'anic schools (also known as dugsi) remain the basic system of traditional religious instruction in Somalia. They provide Islamic education for children, thereby filling a clear religious and social role in the country. Known as the most stable local, non-formal system of education providing basic religious and moral instruction, their strength rests on community support and their use of locally made and widely available teaching materials. The Qur'anic system, which teaches the greatest number of students relative to other educational sub-sectors, is oftentimes the only system accessible to Somalis in nomadic as compared to urban areas. A study from 1993 found, among other things, that "unlike in primary schools where gender disparity is enormous, around 40 per cent of Qur'anic school pupils are girls; but the teaching staff have minimum or no qualification necessary to ensure intellectual development of children." To address these concerns, the Somali government on its own part subsequently established the Ministry of Endowment and Islamic Affairs, under which Qur'anic education is now regulated.
What is another name for a Qur'anic school?

Context and question: Following speculation that Sony was working on a 'slim' model, Sony officially announced the PS3 CECH-2000 model on August 18, 2009, at the Sony Gamescom press conference. New features included a slimmer form factor, decreased power consumption, and a quieter cooling system. It was released in major territories by September 2009. As part of the release for the slim model, the console logo ceased using the "Spider-Man font" (the same font used for the title of Sony's Spider-Man 3) and the capitalized PLAYSTATION 3. It instead reverted to a more traditional PlayStation- and PlayStation 2-like 'PlayStation 3' logo with "PS3" imprinted on the console. Along with the redesigning of the console and logo, the boot screen of all consoles changed from "Sony Computer Entertainment" to "PS3 PlayStation 3", with a new chime and the game start splash screen being dropped. The cover art and packaging of games was also changed.
What font was discontinued with the release of the slim model?
Answer: Spider-Man font
