Context and question: Downtown area is home to historic neighborhoods and buildings such as the Sir Walter Raleigh Hotel built in the early 20th century, the restored City Market, the Fayetteville Street downtown business district, which includes the PNC Plaza and Wells Fargo Capitol Center buildings, as well as the North Carolina Museum of History, North Carolina Museum of Natural Sciences, North Carolina State Capitol, Peace College, the Raleigh City Museum, Raleigh Convention Center, Shaw University, and St. Augustine's College. The neighborhoods in Old Raleigh include Cameron Park, Boylan Heights, Country Club Hills, Coley Forest, Five Points, Budleigh, Glenwood-Brooklyn, Hayes Barton Historic District, Moore Square, Mordecai, Rosengarten Park, Belvidere Park, Woodcrest, and Historic Oakwood. In the 2000s, an effort by the Downtown Raleigh Alliance was made to separate this area of the city into five smaller districts: Fayetteville Street, Moore Square, Glenwood South, Warehouse (Raleigh), and Capital District (Raleigh). Some of the names have become common place among locals such as the Warehouse, Fayetteville Street, and Glenwood South Districts.

Context and question: In the Soviet Union, in the 1970s, a comparison was made between systems electrified at 3 kV DC and 25 kV AC (50 Hz). The results showed that percentage losses in the overhead wires (catenary and contact wires) was over 3 times greater for 3 kV DC than for 25 kV AC. But when the conversion losses were all taken into account and added to overhead wire losses (including cooling blower energy) the 25 kV AC lost a somewhat higher percent of energy than for 3 kV DC. Thus in spite of the much higher losses in the catenary, the 3 kV DC was a little more energy efficient than AC in providing energy from the USSR power grid to the terminals of the traction motors (all DC at that time). While both systems use energy in converting higher voltage AC from the USSR's power grid to lower voltage DC, the conversions for the DC system all took place (at higher efficiency) in the railway substation, while most of the conversion for the AC system took place inside the locomotive (at lower efficiency). Consider also that it takes energy to constantly move this mobile conversion hardware over the rails while the stationary hardware in the railway substation doesn't incur this energy cost. For more details see: Wiki: Soviet Union DC vs. AC.
What was less energy efficient in than AC in providing energy?
Answer: unanswerable
Context and question: The consuls of the Roman Republic were the highest ranking ordinary magistrates; each consul served for one year. Consuls had supreme power in both civil and military matters. While in the city of Rome, the consuls were the head of the Roman government. They would preside over the senate and the assemblies. While abroad, each consul would command an army. His authority abroad would be nearly absolute. Praetors administered civil law and commanded provincial armies. Every five years, two censors were elected for an 18-month term, during which they would conduct a census. During the census, they could enroll citizens in the senate, or purge them from the senate. Aediles were officers elected to conduct domestic affairs in Rome, such as managing public games and shows. The quaestors would usually assist the consuls in Rome, and the governors in the provinces. Their duties were often financial.
Which official had supremacy in both civil and military matters?
Answer:
Consuls
