Problem: High, cold ice clouds such as Cirrus or Cumulonimbus show up bright white, lower warmer clouds such as Stratus or Stratocumulus show up as grey with intermediate clouds shaded accordingly. Hot land surfaces will show up as dark-grey or black. One disadvantage of infrared imagery is that low cloud such as stratus or fog can be a similar temperature to the surrounding land or sea surface and does not show up. However, using the difference in brightness of the IR4 channel (10.3–11.5 µm) and the near-infrared channel (1.58–1.64 µm), low cloud can be distinguished, producing a fog satellite picture. The main advantage of infrared is that images can be produced at night, allowing a continuous sequence of weather to be studied.
What is the range of the near-infrared channel in micrometers?

Answer: 1.58–1.64


Problem: During the ceremony of initiation, the candidate is expected to swear (usually on a volume of sacred text appropriate to his personal religious faith) to fulfil certain obligations as a Mason. In the course of three degrees, new masons will promise to keep the secrets of their degree from lower degrees and outsiders, and to support a fellow Mason in distress (as far as practicality and the law permit). There is instruction as to the duties of a Freemason, but on the whole, Freemasons are left to explore the craft in the manner they find most satisfying. Some will further explore the ritual and symbolism of the craft, others will focus their involvement on the social side of the Lodge, while still others will concentrate on the charitable functions of the lodge.
How many degrees must a Mason swear to keep the secrets from outsiders?

Answer: three degrees


Problem: The area between Belvidere Street, Interstate 195, Interstate 95, and the river, which includes Virginia Commonwealth University, is socioeconomically and architecturally diverse. North of Broad Street, the Carver and Newtowne West neighborhoods are demographically similar to neighboring Jackson Ward, with Carver experiencing some gentrification due to its proximity to VCU. The affluent area between the Boulevard, Main Street, Broad Street, and VCU, known as the Fan, is home to Monument Avenue, an outstanding collection of Victorian architecture, and many students. West of the Boulevard is the Museum District, the location of the Virginia Historical Society and the Virginia Museum of Fine Arts. South of the Downtown Expressway are Byrd Park, Maymont, Hollywood Cemetery, the predominantly black working class Randolph neighborhood, and white working class Oregon Hill. Cary Street between Interstate 195 and the Boulevard is a popular commercial area called Carytown.
The neighborhood of Newtowne West is north of what street?

Answer:
Broad
