Problem: Film speed:

The CIPA DC-004 standard requires that Japanese manufacturers of digital still cameras use either the REI or SOS techniques, and DC-008 updates the Exif specification to differentiate between these values. Consequently, the three EI techniques carried over from ISO 12232:1998 are not widely used in recent camera models (approximately 2007 and later). As those earlier techniques did not allow for measurement from images produced with lossy compression, they cannot be used at all on cameras that produce images only in JPEG format.

Which manufacturers are exempt from CIPA DC-004?

A: unanswerable


Problem: In 2000, Apple released the Power Mac G4 Cube, their first desktop since the discontinued Power Macintosh G3, to slot between the iMac G3 and the Power Mac G4. Even with its innovative design, it was initially priced US$200 higher than the comparably-equipped and more-expandable base Power Mac G4, while also not including a monitor, making it too expensive and resulting in slow sales. Apple sold just 29,000 Cubes in Q4 of 2000 which was one third of expectations, compared to 308,000 Macs during that same quarter, and Cube sales dropped to 12,000 units in Q1 of 2001. A price drop and hardware upgrades could not offset the earlier perception of the Cube's reduced value compared to the iMac and Power Mac G4 lineup, and it was discontinued in July 2001.
How did the actual sales of the G4's compare to the sales expectations?

Answer: one third of expectations


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Many organisms (of which humans are prime examples) eat from multiple levels of the food chain and, thus, make this classification problematic. A carnivore may eat both secondary and tertiary consumers, and its prey may itself be difficult to classify for similar reasons. Organisms showing both carnivory and herbivory are known as omnivores. Even herbivores such as the giant panda may supplement their diet with meat. Scavenging of carrion provides a significant part of the diet of some of the most fearsome predators. Carnivorous plants would be very difficult to fit into this classification, producing their own food but also digesting anything that they may trap. Organisms that eat detritivores or parasites would also be difficult to classify by such a scheme.
From how many levels of the food chain do parasites usually eat?
A: unanswerable


Context and question: A similar story is mentioned by Plutarch. He writes that the Cretan seer Epimenides purified Athens after the pollution brought by the Alcmeonidae, and that the seer's expertise in sacrifices and reform of funeral practices were of great help to Solon in his reform of the Athenian state. The story indicates that Epimenides was probably heir to the shamanic religions of Asia, and proves, together with the Homeric hymn, that Crete had a resisting religion up to historical times. It seems that these rituals were dormant in Greece, and they were reinforced when the Greeks migrated to Anatolia.
What group was probably heir to the shemanic religions of Asia?
Answer: Epimenides


Question: The first lighting used on an airport was during the latter part of the 1920s; in the 1930s approach lighting came into use. These indicated the proper direction and angle of descent. The colours and flash intervals of these lights became standardized under the International Civil Aviation Organization (ICAO). In the 1940s, the slope-line approach system was introduced. This consisted of two rows of lights that formed a funnel indicating an aircraft's position on the glideslope. Additional lights indicated incorrect altitude and direction.
Is there an answer to this question: When was the slope-line approach system introduced?

Answer: 1940s
