Problem: Question: "What did West originally say to defend his actions?"  Context: "On September 13, 2009, during the 2009 MTV Video Music Awards while Taylor Swift was accepting her award for Best Female Video for "You Belong with Me", West went on stage and grabbed the microphone to proclaim that Beyoncé's video for "Single Ladies (Put a Ring on It)", nominated for the same award, was "one of the best videos of all time". He was subsequently removed from the remainder of the show for his actions. When Beyoncé later won the award for Best Video of the Year for "Single Ladies (Put a Ring on It)", she called Swift up on stage so that she could finish her acceptance speech. West was criticized by various celebrities for the outburst, and by President Barack Obama, who called West a "jackass". In addition, West's VMA disruption sparked a large influx of Internet photo memes with blogs, forums and "tweets" with the "Let you finish" photo-jokes. He posted a Tweet soon after the event where he stated, "Everybody wanna booooo me but I'm a fan of real pop culture... I'm not crazy y'all, I'm just real." He then posted two apologies for the outburst on his personal blog; one on the night of the incident, and the other the following day, when he also apologized during an appearance on The Jay Leno Show. After Swift appeared on The View two days after the outburst, partly to discuss the matter, West called her to apologize personally. Swift said she accepted his apology."  Answer:

A: "Everybody wanna booooo me but I'm a fan of real pop culture... I'm not crazy y'all, I'm just real."


Problem: Question: "Why was the middle part of A Prophet's Song unique?"  Context: "In late 1975, Queen recorded and released A Night at the Opera, taking its name from the popular Marx Brothers movie. At the time, it was the most expensive album ever produced. Like its predecessor, the album features diverse musical styles and experimentation with stereo sound. In "The Prophet's Song", an eight-minute epic, the middle section is a canon, with simple phrases layered to create a full-choral sound. The Mercury penned ballad, "Love of My Life", featured a harp and overdubbed vocal harmonies. The album was very successful in Britain, and went triple platinum in the United States. The British public voted it the 13th greatest album of all time in a 2004 Channel 4 poll. It has also ranked highly in international polls; in a worldwide Guinness poll, it was voted the 19th greatest of all time, while an ABC poll saw the Australian public vote it the 28th greatest of all time. A Night at the Opera has frequently appeared in "greatest albums" lists reflecting the opinions of critics. Among other accolades, it was ranked number 16 in Q Magazine's "The 50 Best British Albums Ever" in 2004, and number 11 in Rolling Stone's "The 100 Greatest Albums of All Time" as featured in their Mexican edition in 2004. It was also placed at No. 230 on Rolling Stone magazine's list of "The 500 Greatest Albums of All Time" in 2003. A Night at the Opera is the third and final Queen album to be featured in the book 1001 Albums You Must Hear Before You Die."  Answer:

A: middle section is a canon


Problem: Question: "Why are C4 pathways used?"  Context: "Plants synthesize a number of unique polymers like the polysaccharide molecules cellulose, pectin and xyloglucan from which the land plant cell wall is constructed. Vascular land plants make lignin, a polymer used to strengthen the secondary cell walls of xylem tracheids and vessels to keep them from collapsing when a plant sucks water through them under water stress. Lignin is also used in other cell types like sclerenchyma fibers that provide structural support for a plant and is a major constituent of wood. Sporopollenin is a chemically resistant polymer found in the outer cell walls of spores and pollen of land plants responsible for the survival of early land plant spores and the pollen of seed plants in the fossil record. It is widely regarded as a marker for the start of land plant evolution during the Ordovician period. The concentration of carbon dioxide in the atmosphere today is much lower than it was when plants emerged onto land during the Ordovician and Silurian periods. Many monocots like maize and the pineapple and some dicots like the Asteraceae have since independently evolved pathways like Crassulacean acid metabolism and the C4 carbon fixation pathway for photosynthesis which avoid the losses resulting from photorespiration in the more common C3 carbon fixation pathway. These biochemical strategies are unique to land plants."  Answer:

A: avoid the losses resulting from photorespiration


Problem: Question: "How does the break down of trees begin?"  Context: "It is remarkable that the inner heartwood of old trees remains as sound as it usually does, since in many cases it is hundreds, and in a few instances thousands, of years old. Every broken limb or root, or deep wound from fire, insects, or falling timber, may afford an entrance for decay, which, once started, may penetrate to all parts of the trunk. The larvae of many insects bore into the trees and their tunnels remain indefinitely as sources of weakness. Whatever advantages, however, that sapwood may have in this connection are due solely to its relative age and position."  Answer:

A:
deep wound from fire, insects, or falling timber
