Problem: The median lethal dose (LD50) for acute radiation exposure is about 4.5 Sievert. The committed effective dose equivalent (CEDE) 210Po is 0.51 µSv/Becquerel if ingested, and 2.5 µSv/Bq if inhaled. So a fatal 4.5 Sv dose can be caused by ingesting , about 50 nanograms (ng), or inhaling , about 10 ng. One gram of 210Po could thus in theory poison 20 million people of whom 10 million would die. The actual toxicity of 210Po is lower than these estimates because radiation exposure that is spread out over several weeks (the biological half-life of polonium in humans is 30 to 50 days) is somewhat less damaging than an instantaneous dose. It has been estimated that a median lethal dose of 210Po is , or 0.089 micrograms, still an extremely small amount. For comparison, one grain of salt is about 0.06 mg  60 μg.

How many people, in theory, would be poisoned by one gram of 210Po, but live?
Answer: 10 million

Problem: Albania is a secular state without an official religion, with the freedom of religion being a Constitution of Albania right. The 2011 census, for the first time since 1930, included an optional open-ended question on religion; the census recorded a majority of Muslims (58.79%), which include Sunni (56.70%) and Bektashi Muslims (2.09%). Christians,  making up 16.92% of the population, include Roman Catholics (10.03%), Eastern Orthodox Church (6.75%) and Evangelicalism Protestants (0.14%). Atheists accounted for 2.5% of the population and 5.49% were non-affiliated believers, while 13.79% preferred not to answer.

How many percent of people were not atheists?
Answer: 97.5

Problem: The total population in sub-Saharan Africa is projected to increase to almost one billion people, making it the most populated region outside of South-Central Asia. According to the United Nations, the population of Nigeria will reach 411 million by 2050. Nigeria might then be the 3rd most populous country in the world. In 2100, the population of Nigeria may reach 794 million. While the overall population is expected to increase, the growth rate is estimated to decrease from 1.2 percent per year in 2010 to 0.4 percent per year in 2050. The birth rate is also projected to decrease from 20.7 to 13.7, while the death rate is projected to increase from 8.5 in 2010 to 9.8 in 2050. List of countries by life expectancy is all expected to increase from 67.0 years in 2010 to 75.2 years in 2050. By 2050 the percent of the population estimated to be living in urban areas is 69.6% compared to the 50.6% in 2010.

By how many percentage points is the birth rate projected to decrease from 2010 to 2050?
Answer: 7

Problem: Hoping to keep their three-game winning streak going, the Rams returned home for an NFC West fight with the Seattle Seahawks. The Rams struck first, as QB Marc Bulger completed a 9-yard TD pass to WR Torry Holt. Yet, the Seahawks responded with QB Matt Hasselbeck completing a 14-yard TD pass to WR Deion Branch. In the second quarter, St. Louis began pulling away, as RB Steven Jackson ran 2 yards for a touchdown and the duo of Bulger and Holt hooked up again with a 10-yard TD pass. In the third quarter, the Seahawks started to creep back as Hasselbeck completed a 42-yard TD pass to WR Darrell Jackson.  In the fourth quarter, Seattle managed to take the lead with kicker Josh Brown nailing a 49-yard field goal, Hasselbeck throwing a 19-yard TD pass to Branch, and Brown kicking another 49-yard field goal.  The Rams responded with Bulger and Holt completing a 67-yard TD pass. The Seahawks won as Brown kicked a 54-yard field goal as time ran out, giving Seattle a three-game winning streak against St. Louis.  This game was marred by controversy as the 10-second run-off rule did not apply on the last play of the game, giving Josh Brown the chance to win the game.  With the loss, the Rams headed into their bye week 4-2.

Which player had the longest touchdown reception?
Answer:
Torry Holt
