Problem: Gene:

Defining exactly what section of a DNA sequence comprises a gene is difficult. Regulatory regions of a gene such as enhancers do not necessarily have to be close to the coding sequence on the linear molecule because the intervening DNA can be looped out to bring the gene and its regulatory region into proximity. Similarly, a gene's introns can be much larger than its exons. Regulatory regions can even be on entirely different chromosomes and operate in trans to allow regulatory regions on one chromosome to come in contact with target genes on another chromosome.

Where can regulatory regions be found?

A: different chromosomes

Problem: The Samoan word for dance is siva with unique gentle movements of the body in time to music and which tells a story, although the Samoan male dances can be more physical and snappy. The sasa is also a traditional dance where rows of dancers perform rapid synchronised movements in time to the rhythm of wooden drums (pate) or rolled mats. Another dance performed by males is called the fa'ataupati or the slap dance, creating rhythmic sounds by slapping different parts of the body. This is believed to have been derived from slapping insects on the body.
What else does the sasa do besides having unique gentle movements of the body to music?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In the Southern Netherlands (now Belgium and Luxembourg) developments were different. Under Spanish, then Austrian, and then French rule standardisation of Dutch language came to a standstill. The state, law, and increasingly education used French, yet more than half the Belgian population were speaking a Dutch dialect. In the course of the nineteenth century the Flemish movement stood up for the rights of Dutch, mostly called Flemish. But in competing with the French language the variation in dialects was a serious disadvantage. Since standardisation is a lengthy process, Dutch-speaking Belgium associated itself with the standard language that had already developed in the Netherlands over the centuries. Therefore, the situation in Belgium is essentially no different from that in the Netherlands, although there are recognisable differences in pronunciation, comparable to the pronunciation differences between standard British and standard American English. In 1980 the Netherlands and Belgium concluded the Language Union Treaty. This treaty lays down the principle that the two countries must gear their language policy to each other, among other things, for a common system of spelling.
What was the name of the treaty that brought the dialects of Belgium and the Netherlands together?
A: Language Union Treaty

Context and question: In about 319, when Athanasius was a deacon, a presbyter named Arius came into a direct conflict with Alexander of Alexandria. It appears that Arius reproached Alexander for what he felt were misguided or heretical teachings being taught by the bishop. Arius's theological views appear to have been firmly rooted in Alexandrian Christianity, and his Christological views were certainly not radical at all. He embraced a subordinationist Christology which taught that Christ was the divine Son (Logos) of God, made, not begotten, heavily influenced by Alexandrian thinkers like Origen, and which was a common Christological view in Alexandria at the time. Support for Arius from powerful bishops like Eusebius of Caesarea and Eusebius of Nicomedia, further illustrate how Arius's subordinationist Christology was shared by other Christians in the Empire. Arius was subsequently excommunicated by Alexander, and he would begin to elicit the support of many bishops who agreed with his position.
What made Arius's belief about Jesus the same from Alexander's?

Question: In the early 1990s, Dell sold its products through Best Buy, Costco and Sam's Club stores in the United States. Dell stopped this practice in 1994, citing low profit-margins on the business, exclusively distributing through a direct-sales model for the next decade. In 2003, Dell briefly sold products in Sears stores in the U.S. In 2007, Dell started shipping its products to major retailers in the U.S. once again, starting with Sam's Club and Wal-Mart. Staples, the largest office-supply retailer in the U.S., and Best Buy, the largest electronics retailer in the U.S., became Dell retail partners later that same year.
Is there an answer to this question: What year did Dell begin selling products at retailers again?

Answer: 2007

Matte solder is usually fused to provide a better bonding surface or stripped to bare copper. Treatments, such as benzimidazolethiol, prevent surface oxidation of bare copper. The places to which components will be mounted are typically plated, because untreated bare copper oxidizes quickly, and therefore is not readily solderable. Traditionally, any exposed copper was coated with solder by hot air solder levelling (HASL). The HASL finish prevents oxidation from the underlying copper, thereby guaranteeing a solderable surface. This solder was a tin-lead alloy, however new solder compounds are now used to achieve compliance with the RoHS directive in the EU and US, which restricts the use of lead. One of these lead-free compounds is SN100CL, made up of 99.3% tin, 0.7% copper, 0.05% nickel, and a nominal of 60ppm germanium.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): The HASL finish encourages oxidation from what?
Ah, so..
