Input: Read this: Northwestern requires that all new buildings be LEED-certified. Silverman Hall on the Evanston campus was awarded Gold LEED Certification in 2010; Wieboldt Hall on the Chicago campus was awarded Gold LEED Certification in 2007, and the Ford Motor Company Engineering Design Center on the Evanston campus was awarded Silver LEED Certification in 2006. New construction and renovation projects will be designed to provide at least a 20% improvement over energy code requirements where technically feasible. The university also released at the beginning of the 200809 academic year the Evanston Campus Framework Plan, which outlines plans for future development of the Evanston Campus. The plan not only emphasizes the sustainable construction of buildings, but also discusses improving transportation by optimizing pedestrian and bicycle access. Northwestern has had a comprehensive recycling program in place since 1990. Annually more than 1,500 tons are recycled at Northwestern, which represents 30% of the waste produced on campus. Additionally, all landscape waste at the university is composted.
Question: How many gallons of waste are recycled at Northwestern yearly?

Output: unanswerable

QUES: As the Soga clan had taken control of the throne in the sixth century, the Fujiwara by the ninth century had intermarried with the imperial family, and one of their members was the first head of the Emperor's Private Office. Another Fujiwara became regent, Sessho for his grandson, then a minor emperor, and yet another was appointed Kampaku. Toward the end of the ninth century, several emperors tried, but failed, to check the Fujiwara. For a time, however, during the reign of Emperor Daigo (897-930), the Fujiwara regency was suspended as he ruled directly.

Who was the first Japanese Emperor to rule directly?
What is the answer?
ANS: unanswerable

QUES: Exposure to antibiotics early in life is associated with increased body mass in humans and mouse models. Early life is a critical period for the establishment of the intestinal microbiota and for metabolic development. Mice exposed to subtherapeutic antibiotic treatment (STAT) with either penicillin, vancomycin, penicillin and vancomycin, or chlortetracycline had altered composition of the gut microbiota as well as its metabolic capabilities. Moreover, research have shown that mice given low-dose penicillin (1 g/g body weight) around birth and throughout the weaning process had an increased body mass and fat mass, accelerated growth, and increased hepatic expression of genes involved in adipogenesis, compared to controlled mice. In addition, penicillin in combination with a high-fat diet increased fasting insulin levels in mice. However, it is unclear whether or not antibiotics cause obesity in humans. Studies have found a correlation between early exposure of antibiotics (<6 months) and increased body mass (at 10 and 20 months). Another study found that the type of antibiotic exposure was also significant with the highest risk of being overweight in those given macrolides compared to penicillin and cephalosporin. Therefore, there is correlation between antibiotic exposure in early life and obesity in humans, but whether or not there is a causal relationship remains unclear. Although there is a correlation between antibiotic use in early life and obesity, the effect of antibiotics on obesity in humans needs to be weighed against the beneficial effects of clinically indicated treatment with antibiotics in infancy.
Why do physicians use antibiotics on infants when the relationship has been proven?

ANS: weighed against the beneficial effects

Adult contemporary traces its roots to the 1960s easy listening format, which adopted a 70-80% instrumental - 20-30% vocal mix. A few offered 90% instrumentals, and a handful were entirely instrumental. The easy listening format, as it was first known, was born of a desire by some radio stations in the late 1950s and early 1960s to continue playing current hit songs but distinguish themselves from being branded as "rock and roll" stations. Billboard first published the Easy Listening chart July 17, 1961, with 20 songs; the first number one was "Boll Weevil Song" by Brook Benton. The chart described itself as "not too far out in either direction".
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Generally speaking, what percentage of music on easy listening stations was instrumental?
Ah, so.. 70-80%

Question: Approximately 10,000 years ago, desertification forced hunter-gatherer societies south into the Sahel regions of northern Central Africa, where some groups settled and began farming as part of the Neolithic Revolution. Initial farming of white yam progressed into millet and sorghum, and before 3000 BC the domestication of African oil palm improved the groups' nutrition and allowed for expansion of the local populations. Bananas arrived in the region and added an important source of carbohydrates to the diet; they were also used in the production of alcoholic beverages.[when?] This Agricultural Revolution, combined with a "Fish-stew Revolution", in which fishing began to take place, and the use of boats, allowed for the transportation of goods. Products were often moved in ceramic pots, which are the first known examples of artistic expression from the region's inhabitants.
Try to answer this question if possible: What did a Fish-stew revolution do to the group's eating habits?
Answer: unanswerable

QUES: Out of former Soviet Union republics Uzbekistan continued and expanded the program of child labour on industrial scale to increase profits on the main source of Islam Karimov's income, cotton harvesting. In September, when school normally starts, the classes are suspended and children are sent to cotton fields for work, where they are assigned daily quotas of 20 to 60 kg of raw cotton they have to collect. This process is repeated in spring, when collected cotton needs to be hoed and weeded. In 2006 it is estimated that 2.7 million children were forced to work this way.
Did they have daily quotas for cotton?

ANS:
daily quotas of 20 to 60 kg of raw cotton
