Article: 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.

Question: With what cameras can earlier techniques not be used?
Ans: cameras that produce images only in JPEG format


Article: The ancient-Chamorro society had four classes: chamorri (chiefs), matua (upper class), achaot (middle class), and mana'chang (lower class).:20–21 The matua were located in the coastal villages, which meant they had the best access to fishing grounds, whereas the mana'chang were located in the interior of the island. Matua and mana'chang rarely communicated with each other, and matua often used achaot as intermediaries. There were also "makåhna" (similar to shamans), skilled in healing and medicine. Belief in spirits of ancient Chamorros called "Taotao mo'na" still persists as a remnant of pre-European culture. Their society was organized along matrilineal clans.:21

Question: Where were the mana'chag located?
Ans: interior of the island

Article: St. John's, and the province as a whole, was gravely affected in the 1990s by the collapse of the Northern cod fishery, which had been the driving force of the provincial economy for hundreds of years. After a decade of high unemployment rates and depopulation, the city's proximity to the Hibernia, Terra Nova and White Rose oil fields has led to an economic boom that has spurred population growth and commercial development. As a result, the St. John's area now accounts for about half of the province's economic output.

Ans:
1990s
