Problem: As of 2009, dial up, wireless and satellite services were available. Dial up internet services in Somalia were among the fastest growing on the continent, with an annual landline growth rate of over 12.5%. The increase in usage was largely due to innovative policy initiatives adopted by the various Somali telecom operators, including free local in-town calls, a flat rate of $10 per month for unlimited calls, a low charge of $0.005 per minute for Internet connections, and a one-time connection fee of $50. Global Internet Company, a firm jointly owned by the major Somali telecommunication networks Hormuud Telecom, Telcom Somalia and Nationlink, was the country's largest ISP. It was at the time the only provider of dial up services in Somalia's south-central regions. In the northern Puntland and Somaliland regions, online networks offered internet dial up services to their own group of subscribers. Among these firms was Golis Telecom Somalia in the northeast and Telesom in the northwest.
How much did telecom operators charge for text messaging?

After the Marzpanate period (428–636), Armenia emerged as the Emirate of Armenia, an autonomous principality within the Arabic Empire, reuniting Armenian lands previously taken by the Byzantine Empire as well. The principality was ruled by the Prince of Armenia, and recognized by the Caliph and the Byzantine Emperor. It was part of the administrative division/emirate Arminiya created by the Arabs, which also included parts of Georgia and Caucasian Albania, and had its center in the Armenian city, Dvin. The Principality of Armenia lasted until 884, when it regained its independence from the weakened Arab Empire under King Ashot I Bagratuni.

Context and question: A gymnast's score comes from deductions taken from their start value. The start value of a routine is based on the difficulty of the elements the gymnast attempts and whether or not the gymnast meets composition requirements. The composition requirements are different for each apparatus; this score is called the D score. Deductions in execution and artistry are taken from 10.0. This score is called the E score. The final score is calculated by taking deductions from the E score, and adding the result to the D score. Since 2007, the scoring system has changed by adding bonus plus the execution and then adding those two together to get the final score.
What score is determined by the fans?
Answer: unanswerable


Question: The Revolutionary War soldier Nathan Hale (Yale 1773) was the prototype of the Yale ideal in the early 19th century: a manly yet aristocratic scholar, equally well-versed in knowledge and sports, and a patriot who "regretted" that he "had but one life to lose" for his country. Western painter Frederic Remington (Yale 1900) was an artist whose heroes gloried in combat and tests of strength in the Wild West. The fictional, turn-of-the-20th-century Yale man Frank Merriwell embodied the heroic ideal without racial prejudice, and his fictional successor Frank Stover in the novel Stover at Yale (1911) questioned the business mentality that had become prevalent at the school. Increasingly the students turned to athletic stars as their heroes, especially since winning the big game became the goal of the student body, and the alumni, as well as the team itself.
Is there an answer to this question: What were the obbjects of Frederic Remington's paintings?

Answer: unanswerable
