Problem: Houston:

The Houston area is a leading center for building oilfield equipment. Much of its success as a petrochemical complex is due to its busy ship channel, the Port of Houston. In the United States, the port ranks first in international commerce and tenth among the largest ports in the world. Unlike most places, high oil and gasoline prices are beneficial for Houston's economy, as many of its residents are employed in the energy industry. Houston is the beginning or end point of numerous oil, gas, and products pipelines:

Of what is Houston a center?

A: oilfield equipment

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
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.
What enables an organism to differentiate between self and other?
A: interpretation processes


Context and question: However, during this period, major figures and artists in the scene began leaning away from underground aesthetics. In the music press, the increasingly esoteric writing of post-punk publications soon began to alienate their readerships; it is estimated that within several years, NME suffered the loss of half its circulation. Writers like Paul Morley began advocating "overground brightness" instead of the experimental sensibilities promoted in early years. Morley's own musical collaboration with engineer Gary Langan and programmer J. J. Jeczalik, the Art of Noise, would attempt to bring sampled and electronic sounds to the pop mainstream. A variety of more pop-oriented groups, including ABC, the Associates, Adam and the Ants and Bow Wow Wow (the latter two managed by former Sex Pistols manager Malcolm McLaren) emerged in tandem with the development of the New Romantic subcultural scene. Emphasizing glamour, fashion, and escapism in distinction to the experimental seriousness of earlier post-punk groups, the club-oriented scene drew some suspicion from denizens of the movement.
Which new cultural movement began to emphasize glam, escapism and fashion?
Answer: New Romantic


Question: Naturally occurring glass, especially the volcanic glass obsidian, has been used by many Stone Age societies across the globe for the production of sharp cutting tools and, due to its limited source areas, was extensively traded. But in general, archaeological evidence suggests that the first true glass was made in coastal north Syria, Mesopotamia or ancient Egypt. The earliest known glass objects, of the mid third millennium BCE, were beads, perhaps initially created as accidental by-products of metal-working (slags) or during the production of faience, a pre-glass vitreous material made by a process similar to glazing.
Is there an answer to this question: What glass-like material is made with a method related to sharp cutting?

Answer: unanswerable


QUES: For over a century, New Haven citizens had fought in the colonial militia alongside regular British forces, as in the French and Indian War. As the American Revolution approached, General David Wooster and other influential residents hoped that the conflict with the government in Britain could be resolved short of rebellion. On 23 April 1775, which is still celebrated in New Haven as Powder House Day, the Second Company, Governor's Foot Guard, of New Haven entered the struggle against the governing British parliament. Under Captain Benedict Arnold, they broke into the powder house to arm themselves and began a three-day march to Cambridge, Massachusetts. Other New Haven militia members were on hand to escort George Washington from his overnight stay in New Haven on his way to Cambridge. Contemporary reports, from both sides, remark on the New Haven volunteers' professional military bearing, including uniforms.

Toward what area did the New Haven militia march for three days following the powder house incident?
What is the answer?
ANS:
Cambridge, Massachusetts
