Richmond emerged a decade after the smoldering rubble of the Civil War to resume its position as an economic powerhouse, with iron front buildings and massive brick factories. Canal traffic peaked in the 1860s and slowly gave way to railroads, allowing Richmond to become a major railroad crossroads, eventually including the site of the world's first triple railroad crossing. Tobacco warehousing and processing continued to play a role, boosted by the world's first cigarette-rolling machine, invented by James Albert Bonsack of Roanoke in 1880/81. Contributing to Richmond's resurgence was the first successful electrically powered trolley system in the United States, the Richmond Union Passenger Railway. Designed by electric power pioneer Frank J. Sprague, the trolley system opened its first line in 1888, and electric streetcar lines rapidly spread to other cities across the country. Sprague's system used an overhead wire and trolley pole to collect current, with electric motors on the car's trucks. In Richmond, the transition from streetcars to buses began in May 1947 and was completed on November 25, 1949.
Who was the inventor of the cigarette-rolling machine?
****
The answer: James Albert Bonsack

The Latin alphabet of the time still lacked the letters j and w, and there was no v as distinct from u; moreover native Old English spellings did not use k, q or z. The remaining 20 Latin letters were supplemented by four more: (sc, modern ash) and (t, now called eth or edh), which were modified Latin letters, and thorn and wynn , which are borrowings from the futhorc. A few letter pairs were used as digraphs, representing a single sound. Also used was the Tironian note (a character similar to the digit 7) for the conjunction and, and a thorn with a crossbar through the ascender for the pronoun t. Macrons over vowels were originally used not to mark long vowels (as in modern editions), but to indicate stress, or as abbreviations for a following m or n.
When the Latin alphabet was introduced to Old English, what letter was the same as v?
****
The answer: u

Ottoman Turkish was the official language of the Empire. It was an Oghuz Turkic language highly influenced by Persian and Arabic. The Ottomans had several influential languages: Turkish, spoken by the majority of the people in Anatolia and by the majority of Muslims of the Balkans except in Albania and Bosnia; Persian, only spoken by the educated; Arabic, spoken mainly in Arabia, North Africa, Iraq, Kuwait, the Levant and parts of the Horn of Africa; and Somali throughout the Horn of Africa. In the last two centuries, usage of these became limited, though, and specific: Persian served mainly as a literary language for the educated, while Arabic was used for religious rites.
What language was used for religious uses in the Empire?
****
The answer: Arabic

The problem: Answer a question about this article:
Early MPEG Layer III encoders used what is now called Constant Bit Rate (CBR). The software was only able to use a uniform bitrate on all frames in an MP3 file. Later more sophisticated MP3 encoders were able to use the bit reservoir to target an average bit rate selecting the encoding rate for each frame based on the complexity of the sound in that portion of the recording.
What does the term CBR mean?
****
The answer:
Constant Bit Rate
