Problem: With high cost of labor in developed countries, production automation has become increasingly popular. Rather than being assembled by hand, mosaics designed using computer aided design (CAD) software can be assembled by a robot. Production can be greater than 10 times faster with higher accuracy. But these "computer" mosaics have a different look than hand-made "artisanal" mosaics. With robotic production, colored tiles are loaded into buffers, and then the robot picks and places tiles individually according to a command file from the design software.
How does the robot pick the tiles it places?
The answer is the following: a command file

Problem: Residents of Norfolk Island do not pay Australian federal taxes, creating a tax haven for locals and visitors alike. Because there is no income tax, the island's legislative assembly raises money through an import duty, fuel levy, medicare levy, GST of 12% and local/international phone calls. In a move that apparently surprised many islanders the Chief Minister of Norfolk Island, David Buffett, announced on 6 November 2010 that the island would voluntarily surrender its tax free status in return for a financial bailout from the federal government to cover significant debts. The introduction of income taxation will now come into effect on July 1, 2016, with a variation of opinion on the island about these changes but with many understanding that for the island's governance to continue there is a need to pay into the commonwealth revenue pool so that the island can have assistance in supporting its delivery of State government responsibilities such as health, education, medicare, and infrastructure. Prior to these reforms residents of Norfolk Island were not entitled to social services. It appears that the reforms do extend to companies and trustees and not only individuals.
Norfolk Island inhabitants and visitors don't pay what?
The answer is the following: Australian federal taxes

Problem: 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.
What part of a gene can be much larger than its exons?
The answer is the following: a gene's introns

Problem: The atmosphere is severely dry nine months of the year, and average annual snowfall is only 18 inches (46 cm), due to the rain shadow effect. Western passes receive small amounts of fresh snow each year but remain traversible all year round. Low temperatures are prevalent throughout these western regions, where bleak desolation is unrelieved by any vegetation bigger than a low bush, and where wind sweeps unchecked across vast expanses of arid plain. The Indian monsoon exerts some influence on eastern Tibet. Northern Tibet is subject to high temperatures in the summer and intense cold in the winter.
What weather pattern exerts some influence on eastern TIbet?
The answer is the following:
Indian monsoon
