For fans of BBC America's majestically complicated drama Orphan Black, this might be the toughest task they face all year: Explaining to newbies what the heck is going on just before the new season starts on Saturday.

Spoiler alert: Several plot points from the new season are discussed below

The series started with Sarah Manning, a con artist and onetime street urchin, stumbling upon a well-dressed woman who looked exactly like her, crying on a train platform — just before jumping in front of an oncoming train.

On the morning of April 19, 1995, a truck bomb exploded at the Alfred P. Murrah Federal Building in Oklahoma City. The blast — equal to 4,000 pounds of TNT — killed 168 people and injured hundreds more.

The federal office building also housed a day care center. The explosives-laden truck was parked directly beneath it. Of the 21 children there that morning, only six survived.

The World Bank's goal is to end extreme poverty and to grow income for the poorest people on the planet.

The bank does this by lending money and giving grants to governments and private corporations in some of the least developed places on the planet. For example, money goes to preserving land, building dams and creating health care systems.

Once a sleepy border town, Reyhanli, Turkey, is now bursting with Syrian refugees, many of them school-age. More than half a million Syrian refugee children are out of school, and the education crisis is fueling an epidemic of early marriage, child labor and bleak futures.

"I just finished the 12th grade and I don't know what to do," says Abdullah Mustapha, a refugee from the Syrian town of Hama.

In fluent English, he talks about his dreams of a college education, but he doesn't speak Turkish well enough to pass the language test required for state universities.

Nearly a million people will line the streets to watch the Boston Marathon on Monday, and someone else will be watching them. Bill Ridge with the Boston Police says video surveillance is a big part of the security plan.

"We've got a lot of cameras out there," he says. "We're going to be watching the portions in Boston — particularly the routes along Boylston Street, the finish line."
