QUES: BYU has designated energy conservation, products and materials, recycling, site planning and building design, student involvement, transportation, water conservation, and zero waste events as top priority categories in which to further its efforts to be an environmentally sustainable campus. The university has stated that "we have a responsibility to be wise stewards of the earth and its resources." BYU is working to increase the energy efficiency of its buildings by installing various speed drives on all pumps and fans, replacing incandescent lighting with fluorescent lighting, retrofitting campus buildings with low-E reflective glass, and upgraded roof insulation to prevent heat loss. The student groups BYU Recycles, Eco-Response, and BYU Earth educate students, faculty, staff, and administrators about how the campus can decrease its environmental impact. BYU Recycles spearheaded the recent campaign to begin recycling plastics, which the university did after a year of student campaigning.
What is BYU working to increase by installing various speed drives on all pumps and fans?

ANS: energy efficiency of its buildings

QUES: Tibet retained nominal power over religious and regional political affairs, while the Mongols managed a structural and administrative rule over the region, reinforced by the rare military intervention. This existed as a "diarchic structure" under the Yuan emperor, with power primarily in favor of the Mongols. Mongolian prince Khuden gained temporal power in Tibet in the 1240s and sponsored Sakya Pandita, whose seat became the capital of Tibet. Drogön Chögyal Phagpa, Sakya Pandita's nephew became Imperial Preceptor of Kublai Khan, founder of the Yuan dynasty.
What did the Mongols retain nominal power over?

ANS: unanswerable

QUES: Apple released the Macintosh Plus on January 10, 1986, for a price of US$2,600. It offered one megabyte of RAM, easily expandable to four megabytes by the use of socketed RAM boards. It also featured a SCSI parallel interface, allowing up to seven peripherals—such as hard drives and scanners—to be attached to the machine. Its floppy drive was increased to an 800 kB capacity. The Mac Plus was an immediate success and remained in production, unchanged, until October 15, 1990; on sale for just over four years and ten months, it was the longest-lived Macintosh in Apple's history. In September 1986, Apple introduced the Macintosh Programmer's Workshop, or MPW, an application that allowed software developers to create software for Macintosh on Macintosh, rather than cross compiling from a Lisa. In August 1987, Apple unveiled HyperCard and MultiFinder, which added cooperative multitasking to the Macintosh. Apple began bundling both with every Macintosh.
What was the longest-lived Macintosh in Apple's history while it was in production?

ANS: The Mac Plus

QUES: In January 2009, the Green Power Partnership (GPP, sponsored by the EPA) listed Northwestern as one of the top 10 universities in the country in purchasing energy from renewable sources. The university matches 74 million kilowatt hours (kWh) of its annual energy use with Green-e Certified Renewable Energy Certificates (RECs). This green power commitment represents 30 percent of the university's total annual electricity use and places Northwestern in the EPA's Green Power Leadership Club. The 2010 Report by The Sustainable Endowments Institute awarded Northwestern a "B-" on its College Sustainability Report Card. The Initiative for Sustainability and Energy at Northwestern (ISEN), supporting research, teaching and outreach in these themes, was launched in 2008.
How much of the university's total annual electric bill is represented by the green power commitment?

ANS:
30 percent
