Q: Coming off a devastating home loss to the Pittsburgh Steelers, the Browns stayed at home as they faced the Cincinnati Bengals in Round 2 of the Battle of Ohio.  However, this match-up would find Cleveland not scoring a single point all game.  In the first quarter, Bengals RB Rudi Johnson got a 1-yard TD run for the only score of the period.  In the second quarter, QB Carson Palmer completed a 7-yard TD pass to WR Chris Henry, while kicker Shayne Graham got a 24-yard field goal for another uncontested 10 points.  In the third quarter, Palmer would hook up with WR T. J. Houshmandzadeh on a 6-yard TD pass (along with a failed PAT) for the only score of the period.  In the fourth, Palmer and Henry wrapped up the game on a 10-yard TD pass, shutting out the Cleveland Browns on their home field, 30-0.  With the second loss in a row at their home stadium, the Browns fell to 3-8. Braylon Edwards was involved in a highly publicized altercation with Charlie Frye on the sideline during the game, resulting in Edwards issuing a formal apology for his actions.

Q: The exact origin of the 260-day count is not known, but there are several theories. One theory is that the calendar came from mathematical operations based on the numbers thirteen and twenty, which were important numbers to the Maya. The numbers multiplied together equal 260. Another theory is that the 260-day period came from the length of human pregnancy. This is close to the average number of days between the first missed menstrual period and birth, unlike Naegele's rule which is 40 weeks  between the last menstrual period and birth. It is postulated that midwives originally developed the calendar to predict babies' expected birth dates. A third theory comes from understanding of astronomy, geography and paleontology.  The mesoamerican calendar probably originated with the Olmecs, and a settlement existed at Izapa, in southeast Chiapas Mexico, before 1200 BCE. There, at a latitude of about 15° N, the Sun passes through zenith twice a year, and there are 260 days between zenithal passages, and gnomons , were found at this and other sites. The sacred almanac may well have been set in motion on August 13, 1359 BCE, in Izapa.
How many theories had to do with mathematical operations?

A: 1


Q: Henry VI, elected King of the Romans since 1169, succeeded his father Frederick and was crowned Holy Roman Emperor by Pope Celestine III in 1191. In his struggle with the Princes to enforce his succession, the tide turned in his favour when the returning crusader King Richard was captured in Austria and only released against an oath of allegiance and an enormous ransom. In 1194 Henry could assert the inheritance claims of his wife Constance by conquering the Kingdom of Sicily. By declaring a new Crusade to reconquer Jerusalem, Henry aimed at an agreement with Pope Celestine III to acknowledge his rule over Sicily. In 1195 the armistice concluded by King Richard ended. Sultan Saladin had already died in 1193 and a conflict over his succession raged in the Ayyubid lands. In view of these favourable developments, the emperor hoped to continue the momentum of the previous campaign. Henry VI decided to take advantage of his father's threat of force against  the Byzantine Empire, affected by the rebellions in Serbia and Bulgaria as well as by Seljuk incursions. Emperor Isaac II Angelos had maintained close ties with the Sicilian ursurper king Tancred of Lecce, he was overthrown in April 1195 by his brother Alexios III Angelos. Henry took the occasion to exact tribute and had a threatening letter sent to the Byzantine emperor in order to finance the planned Crusade. Alexius immediately submitted to the tributary demands and exacted high taxes from his subjects to pay the Crusaders 5,000 pounds of gold. Henry also forged alliances with King Amalric of Cyprus and Prince Leo of Cilicia.
