Passage: The Ravens wore their alternate uniforms in the game, hosting cross-conference rivals The Washington Redskins at M&T Bank Stadium. The Ravens scored early following an Ed Reed interception that set up a short touchdown pass from Joe Flacco to Le'Ron McClain. With just under ten minutes to go, Washington ran Clinton Portis up the middle for a first down, but Portis fumbled. Raven Ed Reed recovered the ball and advanced it for a touchdown; the Redskins unsuccessfully challenged, contending Portis was down by contact. Those would be the only points on the board for either team in the first half. In the second half, a long Ravens drive beginning at just under eleven minutes to go in the third quarter set up a 32-yard Matt Stover field goal. The Redskins answered with a drive starting late in the third quarter and ending in the early fourth quarter that set up a 43-yard Shaun Suisham field goal. Receiving the kickoff, Baltimore ran just two plays before surrendering the ball to Washington on a Willis McGahee fumble that led to a short drive capped by a touchdown pass from Jason Campbell to Antwaan Randle El. Another kickoff led to a very long Baltimore drive that consumed most of the remaining time. Ten of twelve plays were runs by Le'Ron McClain. A 28-yard touchdown pass to Derrick Mason capped this drive. With three and a half minutes left, the Redskins next drive ended in an Ed Reed interception that enabled Baltimore to burn most of the remaining time. The Redskins took possession for their final series with 0:16 remaining but could not score. 
Question: How many interceptions did Ed Reed have?

Passage: 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. 
Question: How many subjects comprise the third theory? 
Answer type: Number

Passage: The control of Tenasserim coast  in the early 18th century was divided between Burma and Siam, with the Burmese controlling down to Tavoy  and the Siamese controlling the rest. Throughout history, both kingdoms had claimed the entire coast--, and control had changed hands several times. The Burmese Pagan Dynasty controlled the entire coast until 1287. Throughout 14th and 16th centuries, Siamese kingdoms  controlled much of the coast, up to just south of present-day Mawlamyaing. In the mid-16th century, the Burmese under Toungoo kings Tabinshwehti and Bayinnaung tried to regain the coast, first failing in 1548, and finally succeeding in 1564 when they conquered all of Siam for the first time. The Siamese revolted in 1584, and under their king Naresuan regained the lower coast by 1593 and the entire coast by 1594. The Burmese retook the upper coast down to Tavoy in 1615 but failed to recover the rest. This arrangement lasted until 1740 . During this period, Mergui  on the Andaman Sea was the primary port of Siam through which its trade with India and the West was conducted. 
Question: How many years was it between the Siamese king Naresuan regaining control of the lower coast and when he was able to retake the entire coast?
