Problem: Renewable energy commercialization:

The incentive to use 100% renewable energy, for electricity, transport, or even total primary energy supply globally, has been motivated by global warming and other ecological as well as economic concerns. The Intergovernmental Panel on Climate Change has said that there are few fundamental technological limits to integrating a portfolio of renewable energy technologies to meet most of total global energy demand. In reviewing 164 recent scenarios of future renewable energy growth, the report noted that the majority expected renewable sources to supply more than 17% of total energy by 2030, and 27% by 2050; the highest forecast projected 43% supplied by renewables by 2030 and 77% by 2050. Renewable energy use has grown much faster than even advocates anticipated. At the national level, at least 30 nations around the world already have renewable energy contributing more than 20% of energy supply. Also, Professors S. Pacala and Robert H. Socolow have developed a series of "stabilization wedges" that can allow us to maintain our quality of life while avoiding catastrophic climate change, and "renewable energy sources," in aggregate, constitute the largest number of their "wedges."

 Who rejected a series of stabilization wedges?

Problem: As of 2012, renewable energy plays a major role in the energy mix of many countries globally. Renewables are becoming increasingly economic in both developing and developed countries. Prices for renewable energy technologies, primarily wind power and solar power, continued to drop, making renewables competitive with conventional energy sources. Without a level playing field, however, high market penetration of renewables is still dependent on a robust promotional policies. Fossil fuel subsidies, which are far higher than those for renewable energy, remain in place and quickly need to be phased out.
What plays a major role in the energy mix of no countries?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The emergence of resistance of bacteria to antibiotics is a common phenomenon. Emergence of resistance often reflects evolutionary processes that take place during antibiotic therapy. The antibiotic treatment may select for bacterial strains with physiologically or genetically enhanced capacity to survive high doses of antibiotics. Under certain conditions, it may result in preferential growth of resistant bacteria, while growth of susceptible bacteria is inhibited by the drug. For example, antibacterial selection for strains having previously acquired antibacterial-resistance genes was demonstrated in 1943 by the Luria–Delbrück experiment. Antibiotics such as penicillin and erythromycin, which used to have a high efficacy against many bacterial species and strains, have become less effective, due to the increased resistance of many bacterial strains.
What is resistance to antibiotics a cause of?
A: evolution


Context and question: Since 1718, transportation to the American colonies had been a penalty for various criminal offences in Britain, with approximately one thousand convicts transported per year across the Atlantic. Forced to find an alternative location after the loss of the 13 Colonies in 1783, the British government turned to the newly discovered lands of Australia. The western coast of Australia had been discovered for Europeans by the Dutch explorer Willem Jansz in 1606 and was later named New Holland by the Dutch East India Company, but there was no attempt to colonise it. In 1770 James Cook discovered the eastern coast of Australia while on a scientific voyage to the South Pacific Ocean, claimed the continent for Britain, and named it New South Wales. In 1778, Joseph Banks, Cook's botanist on the voyage, presented evidence to the government on the suitability of Botany Bay for the establishment of a penal settlement, and in 1787 the first shipment of convicts set sail, arriving in 1788. Britain continued to transport convicts to New South Wales until 1840. The Australian colonies became profitable exporters of wool and gold, mainly because of gold rushes in the colony of Victoria, making its capital Melbourne the richest city in the world and the largest city after London in the British Empire.
Where did Britain switch to sending their convicts after the loss of the American colonies?
Answer: Australia


Question: The best-known medieval Chinese name for Tibet is Tubo (Chinese: 吐蕃 also written as 土蕃 or 土番; pinyin: Tǔbō or Tǔfān). This name first appears in Chinese characters as 土番 in the 7th century (Li Tai) and as 吐蕃 in the 10th-century (Old Book of Tang describing 608–609 emissaries from Tibetan King Namri Songtsen to Emperor Yang of Sui). In the Middle Chinese spoken during that period, as reconstructed by William H. Baxter, 土番 was pronounced thux-phjon and 吐蕃 was pronounced thux-pjon (with the x representing tone).
Is there an answer to this question: What is the best known Chinese name for Tubo?

Answer: unanswerable


Question: The collation of all known variants of a text is referred to as a variorum, namely a work of textual criticism whereby all variations and emendations are set side by side so that a reader can track how textual decisions have been made in the preparation of a text for publication. The Bible and the works of William Shakespeare have often been the subjects of variorum editions, although the same techniques have been applied with less frequency to many other works, such as Walt Whitman's Leaves of Grass, and the prose writings of Edward Fitzgerald.
Is there an answer to this question: Name two works that are often the subject of a variorum.

Answer:
The Bible and the works of William Shakespeare
