Thousands of Muslims living in southern Nigeria are reported to be fleeing north following growing tensions after recent sectarian attacks. Many Christians are reported to be heading in the opposite direction. Last week, dozens of Christians were killed by the militant Islamist Boko Haram as gunmen from the group shot at random in churches, at a community centre and a beauty salon. On Monday, a mosque was reportedly attacked in Edo state in the south, injuring 10 people—apparently in response to last week's fatal shootings of Christians. The president of the Nigerian Christian Association, speaking before the mosque attack, expressed his fears that Nigeria may be on the brink of a civil war.

新闻中提到，清真寺受袭明显是in response to last week's fatal shootings of Christians． 由上下文可知，这是对上周Boko Haram领导的针对基督教徒的扫射的报复。

【正确答案】 C

On the surface the sporting venues in Palembang look grand. But look a little closer, and you'll see that organizers are still trying to get things ready in time. Allegations of graft have marred the SEA Games from the start. Mohammad Nazaruddin, a senior politician from Indonesia's ruling party has been accused of taking bribes worth millions for awarding contracts to build the athletes' rooms. He's consistently denied the allegations but the scandal has cast an ugly shadow on the event. Organizers admit the corruption scandal has impacted Palembang's ability to host a successful Games.

根据organizers are still trying to get things ready in time可知，运动会还没有完全准备好，故排除A。又因为Mohammad Nazaruddin的受贿只是allegation还未证实，故排除B。因此答案选C，受贿丑闻的传言必将给这届运动会带来负面影响。

Congress is studying how to change immigration policies in an effort to get more foreign students to stay and work in the United States. Many foreign students come to the United States to earn advanced degrees in science, technology, engineering and math. But many are unable to get a visa to live and work here after they graduate. So far no agreement has been reached on how to stop this so-called reverse brain drain. The loss of highly skilled workers usually involves developing countries losing them to wealthier ones. Critics say immigration policies in the United States are too restrictive.

文中提到现行的移民措施导致many foreign students…unable to get a visa to live and work in the United States，即许多留学生归国，这将造成许多发展中国家的reverse brain drain“人才回流”。故选A。

This week, President Obama appointed Richard Cordray as director of the Consumer Financial Protection Bureau. The new government agency says it has already made home loans and credit card agreements easier for Americans to understand.
