Problem: Infrared:

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 color do Cirrus clouds appear in infrared?
---
A: white


Problem: High-definition television:

The massive amount of data storage required to archive uncompressed streams meant that inexpensive uncompressed storage options were not available to the consumer. In 2008, the Hauppauge 1212 Personal Video Recorder was introduced. This device accepts HD content through component video inputs and stores the content in MPEG-2 format in a .ts file or in a Blu-ray compatible format .m2ts file on the hard drive or DVD burner of a computer connected to the PVR through a USB 2.0 interface. More recent systems are able to record a broadcast high definition program in its 'as broadcast' format or transcode to a format more compatible with Blu-ray.

 What uncompressed storage option wasn't introduced in 2008?
---
A: unanswerable


Problem: Spectre (2015 film):

In November 2013 MGM and the McClory estate formally settled the issue with Danjaq, LLC—sister company of Eon Productions—with MGM acquiring the full copyright film rights to the concept of Spectre and all of the characters associated with it. With the acquisition of the film rights and the organisation's re-introduction to the series' continuity, the SPECTRE acronym was discarded and the organisation reimagined as "Spectre".

Which company is Danjaq, LLC associated with?
---
A: Eon Productions


Problem: Middle Ages:

In the 13th century mendicant orders—the Franciscans and the Dominicans—who swore vows of poverty and earned their living by begging, were approved by the papacy. Religious groups such as the Waldensians and the Humiliati also attempted to return to the life of early Christianity in the middle 12th and early 13th centuries, but they were condemned as heretical by the papacy. Others joined the Cathars, another heretical movement condemned by the papacy. In 1209, a crusade was preached against the Cathars, the Albigensian Crusade, which in combination with the medieval Inquisition, eliminated them.

Along with the Cathars and Humiliati, what group was notably condemned as heretics in this period?
---
A:
the Waldensians
