Problem: Zinc:

Zinc serves a purely structural role in zinc fingers, twists and clusters. Zinc fingers form parts of some transcription factors, which are proteins that recognize DNA base sequences during the replication and transcription of DNA. Each of the nine or ten Zn2+ ions in a zinc finger helps maintain the finger's structure by coordinately binding to four amino acids in the transcription factor. The transcription factor wraps around the DNA helix and uses its fingers to accurately bind to the DNA sequence.

What role does zinc play in fingers, twists and clusters?

A: structural

Problem: Several commentators have suggested that if the liquidity crisis continues, an extended recession or worse could occur. The continuing development of the crisis has prompted fears of a global economic collapse although there are now many cautiously optimistic forecasters in addition to some prominent sources who remain negative. The financial crisis is likely to yield the biggest banking shakeout since the savings-and-loan meltdown. Investment bank UBS stated on October 6 that 2008 would see a clear global recession, with recovery unlikely for at least two years. Three days later UBS economists announced that the "beginning of the end" of the crisis had begun, with the world starting to make the necessary actions to fix the crisis: capital injection by governments; injection made systemically; interest rate cuts to help borrowers. The United Kingdom had started systemic injection, and the world's central banks were now cutting interest rates. UBS emphasized the United States needed to implement systemic injection. UBS further emphasized that this fixes only the financial crisis, but that in economic terms "the worst is still to come". UBS quantified their expected recession durations on October 16: the Eurozone's would last two quarters, the United States' would last three quarters, and the United Kingdom's would last four quarters. The economic crisis in Iceland involved all three of the country's major banks. Relative to the size of its economy, Iceland's banking collapse is the largest suffered by any country in economic history.

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The first such boom, covering the early years of the city, rode on the lumber industry. (During this period the road now known as Yesler Way won the nickname "Skid Road", supposedly after the timber skidding down the hill to Henry Yesler's sawmill. The later dereliction of the area may be a possible origin for the term which later entered the wider American lexicon as Skid Row.) Like much of the American West, Seattle saw numerous conflicts between labor and management, as well as ethnic tensions that culminated in the anti-Chinese riots of 18851886. This violence originated with unemployed whites who were determined to drive the Chinese from Seattle (anti-Chinese riots also occurred in Tacoma). In 1900, Asians were 4.2% of the population. Authorities declared martial law and federal troops arrived to put down the disorder.
What events occurred in 1885-1886 due to racial disputes?
A: anti-Chinese riots

Context and question: Relatively insensitive film, with a correspondingly lower speed index, requires more exposure to light to produce the same image density as a more sensitive film, and is thus commonly termed a slow film. Highly sensitive films are correspondingly termed fast films. In both digital and film photography, the reduction of exposure corresponding to use of higher sensitivities generally leads to reduced image quality (via coarser film grain or higher image noise of other types). In short, the higher the sensitivity, the grainier the image will be. Ultimately sensitivity is limited by the quantum efficiency of the film or sensor.
What leads to lower quality images?
Answer: reduction of exposure

Question: The province is traditionally known as the "Land of Fish and Rice". True to its name, rice is the main crop, followed by wheat; north Zhejiang is also a center of aquaculture in China, and the Zhoushan fishery is the largest fishery in the country. The main cash crops include jute and cotton, and the province also leads the provinces of China in tea production. (The renowned Longjing tea is a product of Hangzhou.) Zhejiang's towns have been known for handicraft production of goods such as silk, for which it is ranked second among the provinces. Its many market towns connect the cities with the countryside.
Is there an answer to this question: What is the second main crop of the province?

Answer: wheat

Problem: United States dollar:

When the Federal Reserve makes a purchase, it credits the seller's reserve account (with the Federal Reserve). This money is not transferred from any existing fundsit is at this point that the Federal Reserve has created new high-powered money. Commercial banks can freely withdraw in cash any excess reserves from their reserve account at the Federal Reserve. To fulfill those requests, the Federal Reserve places an order for printed money from the U.S. Treasury Department. The Treasury Department in turn sends these requests to the Bureau of Engraving and Printing (to print new dollar bills) and the Bureau of the Mint (to stamp the coins).

Which organization orders existing funds?
