Context and question: For the 2011 season, the Philadelphia Soul, Kansas City Brigade, San Jose SaberCats, New Orleans VooDoo, and the Georgia Force returned to the AFL after having last played in 2008. However, the Grand Rapids Rampage, Colorado Crush, Columbus Destroyers, Los Angeles Avengers, and the New York Dragons did not return. The league added one expansion team, the Pittsburgh Power. Former Pittsburgh Steelers wide receiver Lynn Swann was one of the team's owners. It was the first time the AFL returned to Pittsburgh since the Pittsburgh Gladiators were an original franchise in 1987 before becoming the Tampa Bay Storm. The Brigade changed its name to the Command, becoming the Kansas City Command. Even though they were returning teams, the BossierShreveport Battle Wings moved to New Orleans as the Voodoo, the identity formerly owned by New Orleans Saints owner Tom Benson. The Alabama Vipers moved to Duluth, Georgia to become the new Georgia Force (the earlier franchise of that name being a continuation of the first Nashville Kats franchise). On October 25, 2010 the Oklahoma City Yard Dawgz did not return. The Milwaukee Iron also changed names to the Milwaukee Mustangs, the name of Milwaukee's original AFL team that had existed from 1994 to 2001.
Along with the New Orleans VooDoo, Kansas City Brigade, Philadelphia Soul and Georgia Force, what former team returned for the 2011 season?
Answer: San Jose SaberCats

Question: Today, computer security comprises mainly "preventive" measures, like firewalls or an exit procedure. A firewall can be defined as a way of filtering network data between a host or a network and another network, such as the Internet, and can be implemented as software running on the machine, hooking into the network stack (or, in the case of most UNIX-based operating systems such as Linux, built into the operating system kernel) to provide real time filtering and blocking. Another implementation is a so-called physical firewall which consists of a separate machine filtering network traffic. Firewalls are common amongst machines that are permanently connected to the Internet.
Is there an answer to this question: What types of measures do computer security firms rarely use today?

Answer: unanswerable

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.

How is kaolin placed inside a light bulb?

A:
blown in and electrostatically deposited
