Article: The most important demographic influence in the modern Portuguese seems to be the oldest one; current interpretation of Y-chromosome and mtDNA data suggests that the Portuguese have their origin in Paleolithic peoples that began arriving to the European continent around 45,000 years ago. All subsequent migrations did leave an impact, genetically and culturally, but the main population source of the Portuguese is still Paleolithic. Genetic studies show Portuguese populations not to be significantly different from other European populations.

Question: When did people first start arriving in the European continent?
Ans: 45,000 years ago

Article: Carnival means weeks of events that bring colourfully decorated floats, contagiously throbbing music, luxuriously costumed groups of celebrants of all ages, King and Queen elections, electrifying jump-ups and torchlight parades, the Jouvert morning: the Children's Parades and finally the Grand Parade. Aruba's biggest celebration is a month-long affair consisting of festive "jump-ups" (street parades), spectacular parades and creative contests. Music and flamboyant costumes play a central role, from the Queen elections to the Grand Parade. Street parades continue in various districts throughout the month, with brass band, steel drum and roadmarch tunes. On the evening before Lent, Carnival ends with the symbolic burning of King Momo.

Question: What type of costumes play a central role in the Queen elections?
Ans: flamboyant

Article: Compression efficiency of encoders is typically defined by the bit rate, because compression ratio depends on the bit depth and sampling rate of the input signal. Nevertheless, compression ratios are often published. They may use the Compact Disc (CD) parameters as references (44.1 kHz, 2 channels at 16 bits per channel or 216 bit), or sometimes the Digital Audio Tape (DAT) SP parameters (48 kHz, 216 bit). Compression ratios with this latter reference are higher, which demonstrates the problem with use of the term compression ratio for lossy encoders.

Question: What can CD parameters be used as references for?
Ans: compression ratios

Article: Edgar took the first turn at school, and Dwight was employed as a night supervisor at the Belle Springs Creamery. Edgar asked for a second year, Dwight consented and worked for a second year. At that time, a friend "Swede" Hazlet was applying to the Naval Academy and urged Dwight to apply to the school, since no tuition was required. Eisenhower requested consideration for either Annapolis or West Point with his U.S. Senator, Joseph L. Bristow. Though Eisenhower was among the winners of the entrance-exam competition, he was beyond the age limit for the Naval Academy. He then accepted an appointment to West Point in 1911.

Question: What was Eisenhower's job title during the first year his brother went to college?
Ans:
night supervisor
