[EX Q]: Passage: A rejuvenated Nick Foles got his starting job back after being benched in favor of Case Keenum, who suffered a concussion after last week's loss in Baltimore. However, Foles' return was marred as he struggled to find open receivers and was picked off three times by the Bengals ranked defense. He also took hits throughout the game and he was sacked a few times. The only Rams score was a 5-yard run by Tavon Austin on a reverse play in the second quarter. St. Louis' defense was not a factor all game as they struggled to stop the high-powered Bengals offense led by quarterback Andy Dalton, and receivers A. J. Green, and Tyler Eifert, (the latter left the game with a stinger) who is leading the league in touchdown catches. With the loss, the Rams extended their losing streak to 4 games, making their record 4-7.
Question: Who did Keenum suffer his concussion playing against?

[EX Q]: Passage: After 1960 public sector unions grew rapidly and secured good wages and high pensions for their members. While manufacturing and farming steadily declined, state- and local-government employment quadrupled from 4 million workers in 1950 to 12 million in 1976 and 16.6 million in 2009. In 2009 the U.S. membership of public sector unions surpassed membership of private sector unions for the first time, at 7.9 million and 7.4 million respectively. In 2011 states faced a growing fiscal crisis and the Republicans had made major gains in the 2010 elections. Public sector unions came under heavy attack especially in Wisconsin, as well as Indiana, New Jersey and Ohio from conservative Republican legislatures. Conservative state legislatures tried to drastically reduce the abilities of unions to collectively bargain. Conservatives argued that public unions were too powerful since they helped elect their bosses, and that overly generous pension systems were too heavy a drain on state budgets.

[EX Q]: Passage: In 2000, the INEGI estimated that about eight million Mexican-born people, which then was equivalent to 8.7% of the population of Mexico itself, lived in the United States of America. In that year, the Mexican states sending the greatest numbers of emigrants to the United States were Jalisco (170,793), Michoacan (165,502), and Guanajuato (163,338); the total number of Mexican emigrants to the United States in 2000, both legal and illegal, was estimated at 1,569,157; the great majority of these were men. Approximately 30% of emigrants come from rural communities. In that same year, 260,650 emigrants returned to Mexico. According to the Pew Hispanic Center in 2006, an estimated ten percent of all Mexican citizens lived in the United States. The population of Mexican immigrants residing illegally in the United States fell from around seven million in 2007 to about 6.1 million in 2011. This trajectory has been linked to the economic downturn which started in 2008 and reduced available jobs, and to the introduction of stricter immigration laws in many States. According to the Pew Hispanic Center the total number of Mexican-born people had stagnated in 2010 and then began to fall.
