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 are lower intermediate clouds on infrared?

Problem: Beginning in the 2007–2008 academic year, first-time freshman at KU pay a fixed tuition rate for 48 months according to the Four-Year Tuition Compact passed by the Kansas Board of Regents. For the 2014–15 academic year, tuition was $318 per credit hour for in-state freshman and $828 for out-of-state freshmen. For transfer students, who do not take part in the compact, 2014–15 per-credit-hour tuition was $295 for in-state undergraduates and $785 for out-of-state undergraduates; subject to annual increases. Students enrolled in 6 or more credit hours also paid an annual required campus fee of $888. The schools of architecture, music, arts, business, education, engineering, journalism, law, pharmacy, and social welfare charge additional fees.

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In December 2008, the CTO of Blitz Games announced that it would bring stereoscopic 3D gaming and movie viewing to Xbox 360 and PlayStation 3 with its own technology. This was first demonstrated publicly on PS3 using Sony's own technology in January 2009 at the Consumer Electronics Show. Journalists were shown Wipeout HD and Gran Turismo 5 Prologue in 3D as a demonstration of how the technology might work if it is implemented in the future. Firmware update 3.30 officially allowed PS3 titles to be played in 3D, requiring a compatible display for use. System software update 3.50 prepared it for 3D films. While the game itself must be programmed to take advantage of the 3D technology, titles may be patched to add in the functionality retroactively. Titles with such patches include Wipeout HD, Pain, and Super Stardust HD.
Firmware update 3.33 allowed PS3 titles to be played in what?
A: unanswerable


Context and question: Evidence of Anatomically modern humans in the Indian subcontinent is recorded as long as 75,000 years ago, or with earlier hominids including Homo erectus from about 500,000 years ago. The Indus Valley Civilization which spread and flourished in the northwestern part of the Indian subcontinent from c. 3200 to 1300 BCE, was the first major civilization in South Asia. A sophisticated and technologically advanced urban culture developed in the Mature Harappan period, from 2600 to 1900 BCE. This civilization collapsed at the start of the second millennium BCE and was later followed by the Iron Age Vedic Civilization, which extended over much of the Indo-Gangetic plain and which witnessed the rise of major polities known as the Mahajanapadas. In one of these kingdoms, Magadha, Mahavira and Gautama Buddha propagated their Shramanic philosophies during the fifth and sixth century BCE.
For how long have modern humans lived on the Indian subcontinent?
Answer: 75,000 years

Problem: Thuringia:

The Thuringian population has a significant sex ratio gap, caused by the emigration of young women, especially in rural areas. Overall, there are 115 to 120 men per 100 women in the 25–40 age group ("family founders") which has negative consequences for the birth ratio. Furthermore, the population is getting older and older with some rural municipalities recording more than 30% of over-65s (pensioners). This is a problem for the regional labour market, as there are twice as many people leaving as entering the job market annually.

What has positive consequences for the birth ratio?
