It is estimated that in 480 BC, 50 million people lived in the Achaemenid Empire. The empire at its peak ruled over 44% of the world's population, the highest such figure for any empire in history. In Greek history, the Achaemenid Empire is considered as the antagonist of the Greek city states, for the emancipation of slaves including the Jewish exiles in Babylon, building infrastructures such as road and postal systems, and the use of an official language, the Imperial Aramaic, throughout its territories. The empire had a centralized, bureaucratic administration under the emperor, a large professional army, and civil services, inspiring similar developments in later empires. Furthermore, one of the Seven Wonders of the Ancient World, the Mausoleum at Halicarnassus, was built in the empire between 353 and 350 BC.

What Seven Wonder of the Ancient world was built by the Archaemenid Empire in the 4th Century BC?
Answer: the Mausoleum at Halicarnassus

Along with the general administration of the sport, football associations and competition organisers also enforce good conduct in wider aspects of the game, dealing with issues such as comments to the press, clubs' financial management, doping, age fraud and match fixing. Most competitions enforce mandatory suspensions for players who are sent off in a game. Some on-field incidents, if considered very serious (such as allegations of racial abuse), may result in competitions deciding to impose heavier sanctions than those normally associated with a red card. Some associations allow for appeals against player suspensions incurred on-field if clubs feel a referee was incorrect or unduly harsh.

Sometimes clubs can do what if they feel that a punishment was too harsh?
Answer: appeals

The IEEE 802.3af Power over Ethernet (PoE) standard specifies a more elaborate power negotiation scheme than powered USB. It operates at 48 V DC and can supply more power (up to 12.95 W, PoE+ 25.5 W) over a cable up to 100 meters compared to USB 2.0, which provides 2.5 W with a maximum cable length of 5 meters. This has made PoE popular for VoIP telephones, security cameras, wireless access points and other networked devices within buildings. However, USB is cheaper than PoE provided that the distance is short, and power demand is low.

The IEEE 802.3af Power over Ethernet (PoE) standard specifies a what?
Answer:
more elaborate power negotiation scheme than powered USB
