Article: Even more complex morphological changes are sometimes possible. For example, when starved of amino acids, Myxobacteria detect surrounding cells in a process known as quorum sensing, migrate toward each other, and aggregate to form fruiting bodies up to 500 micrometres long and containing approximately 100,000 bacterial cells. In these fruiting bodies, the bacteria perform separate tasks; this type of cooperation is a simple type of multicellular organisation. For example, about one in 10 cells migrate to the top of these fruiting bodies and differentiate into a specialised dormant state called myxospores, which are more resistant to drying and other adverse environmental conditions than are ordinary cells.

Question: Why do cells of Myxobacteria migrate towards each other?
Ans: aggregate to form fruiting bodies

Article: Orthodox Judaism is the approach to religious Judaism which subscribes to a tradition of mass revelation and adheres to the interpretation and application of the laws and ethics of the Torah as legislated in the Talmudic texts by the Tanaim and Amoraim. These texts were subsequently developed and applied by later authorities, known as the Gaonim, Rishonim, and Acharonim. Orthodox Judaism generally includes Modern Orthodox Judaism ( ) and Ultra-Orthodox or Haredi Judaism ( ), but complete within is a wide range of philosophies. Although Orthodox Judaism would probably be considered the mainstream expression of Judaism prior to the 19th century, for some Orthodox Judaism is a modern self-identification that distinguishes it from traditional pre-modern Judaism.

Question: Orthodox Judaism is a self-identification that distinguishes it from what?
Ans: pre-modern Judaism

Article: In May and June 1835, the area which is now central and northern Melbourne was explored by John Batman, a leading member of the Port Phillip Association in Van Diemen's Land (now known as Tasmania), who claimed to have negotiated a purchase of 600,000 acres (2,400 km2) with eight Wurundjeri elders. Batman selected a site on the northern bank of the Yarra River, declaring that "this will be the place for a village". Batman then returned to Launceston in Tasmania. In early August 1835 a different group of settlers, including John Pascoe Fawkner, left Launceston on the ship Enterprize. Fawkner was forced to disembark at Georgetown, Tasmania, because of outstanding debts. The remainder of the party continued and arrived at the mouth of the Yarra River on 15 August 1835. On 30 August 1835 the party disembarked and established a settlement at the site of the current Melbourne Immigration Museum. Batman and his group arrived on 2 September 1835 and the two groups ultimately agreed to share the settlement.

Question: How many acres did John Batman claim to purchase?
Ans: 600,000

Article: When the Xbox 360 was released, Microsoft's online gaming service Xbox Live was shut down for 24 hours and underwent a major upgrade, adding a basic non-subscription service called Xbox Live Silver (later renamed Xbox Live Free) to its already established premium subscription-based service (which was renamed Gold). Xbox Live Free is included with all SKUs of the console. It allows users to create a user profile, join on message boards, and access Microsoft's Xbox Live Arcade and Marketplace and talk to other members. A Live Free account does not generally support multiplayer gaming; however, some games that have rather limited online functions already, (such as Viva Pinata) or games that feature their own subscription service (e.g. EA Sports games) can be played with a Free account. Xbox Live also supports voice the latter a feature possible with the Xbox Live Vision.

Question: What was the "color" name given to the premium version of Xbox Live?
Ans:
Gold
