Problem: Communication:

Fungi communicate to coordinate and organize their growth and development such as the formation of Marcelia and fruiting bodies. Fungi communicate with their own and related species as well as with non fungal organisms in a great variety of symbiotic interactions, especially with bacteria, unicellular eukaryote, plants and insects through biochemicals of biotic origin. The biochemicals trigger the fungal organism to react in a specific manner, while if the same chemical molecules are not part of biotic messages, they do not trigger the fungal organism to react. This implies that fungal organisms can differentiate between molecules taking part in biotic messages and similar molecules being irrelevant in the situation. So far five different primary signalling molecules are known to coordinate different behavioral patterns such as filamentation, mating, growth, and pathogenicity. Behavioral coordination and production of signaling substances is achieved through interpretation processes that enables the organism to differ between self or non-self, a biotic indicator, biotic message from similar, related, or non-related species, and even filter out "noise", i.e. similar molecules without biotic content.

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Many websites converted their home page to black and white; Sina.com and Sohu, major internet portals, limited their homepages to news items and removed all advertisements. Chinese video sharing websites Youku and Tudou displayed a black background and placed multiple videos showing earthquake footage and news reports. The Chinese version of MSN, cn.msn.com, also displayed banner ads about the earthquake and the relief efforts. Other entertainment websites, including various gaming sites, such as the Chinese servers for World of Warcraft, had shut down altogether, or had corresponding links to earthquake donations. After the moments of silence, in Tiananmen Square, crowds spontaneously burst out cheering various slogans, including "Long Live China". Casinos in Macau closed down.
What did internet portals remove from their home pages?
A: all advertisements

Context and question: A microbrewery, or craft brewery, produces a limited amount of beer. The maximum amount of beer a brewery can produce and still be classed as a microbrewery varies by region and by authority, though is usually around 15,000 barrels (1.8 megalitres, 396 thousand imperial gallons or 475 thousand US gallons) a year. A brewpub is a type of microbrewery that incorporates a pub or other eating establishment. The highest density of breweries in the world, most of them microbreweries, exists in the German Region of Franconia, especially in the district of Upper Franconia, which has about 200 breweries. The Benedictine Weihenstephan Brewery in Bavaria, Germany, can trace its roots to the year 768, as a document from that year refers to a hop garden in the area paying a tithe to the monastery. The brewery was licensed by the City of Freising in 1040, and therefore is the oldest working brewery in the world.
What year was The Benedictine Weihenstephan Brewery first licensed as a brewery?
Answer: 1040

Question: Many smaller clans mentioned within early literature seem to have been present across the rest of the subcontinent. Some of these kings were hereditary; other states elected their rulers. Early "republics" such as the Vajji (or Vriji) confederation centered in the city of Vaishali, existed as early as the 6th century BCE and persisted in some areas until the 4th century CE. The educated speech at that time was Sanskrit, while the languages of the general population of northern India are referred to as Prakrits. Many of the sixteen kingdoms had coalesced to four major ones by 500/400 BCE, by the time of Gautama Buddha. These four were Vatsa, Avanti, Kosala, and Magadha. The Life of Gautam Budhha was mainly associated with these four kingdoms.
Is there an answer to this question: In what language did the educated Indian speak?

Answer: Sanskrit
