Here is a question about this article: Homer uses the terms Achaeans and Danaans (Δαναοί) as a generic term for Greeks in Iliad, and they were probably a part of the Mycenean civilization. The names Achaioi and Danaoi seem to be pre-Dorian belonging to the people who were overthrown. They were forced to the region that later bore the name Achaea after the Dorian invasion. In the 5th century BC, they were redefined as contemporary speakers of Aeolic Greek which was spoken mainly in Thessaly, Boeotia and Lesbos. There are many controversial theories on the origin of the Achaeans. According to one view, the Achaeans were one of the fair-headed tribes of upper Europe, who pressed down over the Alps during the early Iron age (1300 BC) to southern Europe. Another theory suggests that the Peloponnesian Dorians were the Achaeans. These theories are rejected by other scholars who, based on linguistic criteria, suggest that the Achaeans were mainland pre-Dorian Greeks. There is also the theory that there was an Achaean ethnos that migrated from Asia minor to lower Thessaly prior to 2000 BC. Some Hittite texts mention a nation lying to the west called Ahhiyava or Ahhiya. Egyptian documents refer to Ekwesh, one of the groups of sea peoples who attached Egypt during the reign of Merneptah (1213-1203 BCE), who may have been Achaeans.
What is the answer to this question: Where was this origin of this redefinition ?

So... spoken mainly in Thessaly, Boeotia and Lesbos


Here is a question about this article: DST's clock shifts have the obvious disadvantage of complexity. People must remember to change their clocks; this can be time-consuming, particularly for mechanical clocks that cannot be moved backward safely. People who work across time zone boundaries need to keep track of multiple DST rules, as not all locations observe DST or observe it the same way. The length of the calendar day becomes variable; it is no longer always 24 hours. Disruption to meetings, travel, broadcasts, billing systems, and records management is common, and can be expensive. During an autumn transition from 02:00 to 01:00, a clock reads times from 01:00:00 through 01:59:59 twice, possibly leading to confusion.
What is the answer to this question: What added complexity do people working across time zones have to keep track of?
****
So... multiple DST rules


Here is a question about this article: These areas, quartiers sensibles ("sensitive quarters"), are in northern and eastern Paris, namely around its Goutte d'Or and Belleville neighbourhoods. To the north of the city they are grouped mainly in the Seine-Saint-Denis department, and to a lesser extreme to the east in the Val-d'Oise department. Other difficult areas are located in the Seine valley, in Évry et Corbeil-Essonnes (Essonne), in Mureaux, Mantes-la-Jolie (Yvelines), and scattered among social housing districts created by Delouvrier's 1961 "ville nouvelle" political initiative.
What is the answer to this question: Where are the quartiers sensibles located?

So...
northern and eastern Paris
