Article: Houston's highway system has a hub-and-spoke freeway structure serviced by multiple loops. The innermost loop is Interstate 610, which encircles downtown, the medical center, and many core neighborhoods with around a 8-mile (13 km) diameter. Beltway 8 and its freeway core, the Sam Houston Tollway, form the middle loop at a diameter of roughly 23 miles (37 km). A proposed highway project, State Highway 99 (Grand Parkway), will form a third loop outside of Houston, totaling 180 miles in length and making an almost-complete circumference, with the exception of crossing the ship channel. As of June 2014, two of eleven segments of State Highway 99 have been completed to the west of Houston, and three northern segments, totaling 38 miles, are actively under construction and scheduled to open to traffic late in 2015. In addition to the Sam Houston Tollway loop mentioned above, the Harris County Toll Road Authority currently operates four spoke tollways: The Katy Managed Lanes of Interstate 10, the Hardy Toll Road, the Westpark Tollway, and the Fort Bend Parkway Extension. Other spoke roads either planned or under construction include Crosby Freeway, and the future Alvin Freeway.

Question: What encircles the downtown area of Houston?

Article: The vast majority of devices containing LEDs are "safe under all conditions of normal use", and so are classified as "Class 1 LED product"/"LED Klasse 1". At present, only a few LEDsextremely bright LEDs that also have a tightly focused viewing angle of 8 or lesscould, in theory, cause temporary blindness, and so are classified as "Class 2". The opinion of the French Agency for Food, Environmental and Occupational Health & Safety (ANSES) of 2010, on the health issues concerning LEDs, suggested banning public use of lamps which were in the moderate Risk Group 2, especially those with a high blue component in places frequented by children. In general, laser safety regulationsand the "Class 1", "Class 2", etc. systemalso apply to LEDs.

Question: How are most LEDs classified?
Ans: Class 1 LED product

Article: Before the Hellenistic period, Greek colonies had been established on the coast of the Crimean and Taman peninsulas. The Bosporan Kingdom was a multi-ethnic kingdom of Greek city states and local tribal peoples such as the Maeotians, Thracians, Crimean Scythians and Cimmerians under the Spartocid dynasty (438110 BCE). The Spartocids were a hellenized Thracian family from Panticapaeum. The Bosporans had long lasting trade contacts with the Scythian peoples of the Pontic-Caspian steppe, and Hellenistic influence can be seen in the Scythian settlements of the Crimea, such as in the Scythian Neapolis. Scythian pressure on the Bosporan kingdom under Paerisades V led to its eventual vassalage under the Pontic king Mithradates VI for protection, circa 107 BCE. It later became a Roman client state. Other Scythians on the steppes of Central Asia came into contact with Hellenistic culture through the Greeks of Bactria. Many Scythian elites purchased Greek products and some Scythian art shows Greek influences. At least some Scythians seem to have become Hellenized, because we know of conflicts between the elites of the Scythian kingdom over the adoption of Greek ways. These Hellenized Scythians were known as the "young Scythians". The peoples around Pontic Olbia, known as the Callipidae, were intermixed and Hellenized Greco-Scythians.

Question: From whom did the Scythians of Central Asia discover Hellenistic culture?
Ans:
Greeks of Bactria
