QUES: Hunting along migration routes threatens some bird species. The populations of Siberian cranes (Leucogeranus leucogeranus) that wintered in India declined due to hunting along the route, particularly in Afghanistan and Central Asia. Birds were last seen in their favourite wintering grounds in Keoladeo National Park in 2002. Structures such as power lines, wind farms and offshore oil-rigs have also been known to affect migratory birds. Other migration hazards include pollution, storms, wildfires, and habitat destruction along migration routes, denying migrants food at stopover points. For example, in the East AsianAustralasian Flyway, up to 65% of key intertidal habitat at the Yellow Sea migration bottleneck has been destroyed since the 1950s.
What are other migration hazards?

ANS: pollution, storms, wildfires, and habitat destruction

QUES: Much of Yale University's staff, including most maintenance staff, dining hall employees, and administrative staff, are unionized. Clerical and technical employees are represented by Local 34 of UNITE HERE and service and maintenance workers by Local 35 of the same international. Together with the Graduate Employees and Students Organization (GESO), an unrecognized union of graduate employees, Locals 34 and 35 make up the Federation of Hospital and University Employees. Also included in FHUE are the dietary workers at Yale-New Haven Hospital, who are members of 1199 SEIU. In addition to these unions, officers of the Yale University Police Department are members of the Yale Police Benevolent Association, which affiliated in 2005 with the Connecticut Organization for Public Safety Employees. Finally, Yale security officers voted to join the International Union of Security, Police and Fire Professionals of America in fall 2010 after the National Labor Relations Board ruled they could not join AFSCME; the Yale administration contested the election.
What union are Yale's service and maintenance workers a part of?

ANS: Local 35 of the same international

QUES: When John DeStefano, Jr., became mayor of New Haven in 1995, he outlined a plan to transform the city into a major cultural and arts center in the Northeast, which involved investments in programs and projects other than sports franchises. As nearby Bridgeport built new sports facilities, the brutalist New Haven Coliseum rapidly deteriorated. Believing the upkeep on the venue to be a drain of tax dollars, the DeStefano administration closed the Coliseum in 2002; it was demolished in 2007. New Haven's last professional sports team, the New Haven County Cutters, left in 2009. The DeStefano administration did, however, see the construction of the New Haven Athletic Center in 1998, a 94,000-square-foot (8,700 m2) indoor athletic facility with a seating capacity of over 3,000. The NHAC, built adjacent to Hillhouse High School, is used for New Haven public schools athletics, as well as large-scale area and state sporting events; it is the largest high school indoor sports complex in the state.
What is the approximate seating capacity of the New Haven Athletic Center?

ANS: over 3,000

QUES: Muslim scientists contributed to advances in the sciences. They placed far greater emphasis on experiment than had the Greeks. This led to an early scientific method being developed in the Muslim world, where progress in methodology was made, beginning with the experiments of Ibn al-Haytham (Alhazen) on optics from circa 1000, in his Book of Optics. The most important development of the scientific method was the use of experiments to distinguish between competing scientific theories set within a generally empirical orientation, which began among Muslim scientists. Ibn al-Haytham is also regarded as the father of optics, especially for his empirical proof of the intromission theory of light. Some have also described Ibn al-Haytham as the "first scientist." al-Khwarzimi's invented the log base systems that are being used today, he also contributed theorems in trigonometry as well as limits. Recent studies show that it is very likely that the Medieval Muslim artists were aware of advanced decagonal quasicrystal geometry (discovered half a millennium later in the 1970s and 1980s in the West) and used it in intricate decorative tilework in the architecture.
What type of geometry was first discovered in the West?

ANS:
