Which state has a climate that's more suitable for growing citrus fruits: California or Maine? Which country has the world's largest Muslim population: Mexico or Indonesia? The port of Rotterdam is built on the delta of which major European river? Those questions, from one of the geography bee's sample quizzes, are of the type that students in Grades 4-8 can expect to face in the Alex Trebek-hosted event, which delves far deeper into the subject than mere capital cities. — Jeff Gemmill

Saving Africa's Witch Children
8/7c HBO2
Growing up in poverty can be hard enough on a child, but it's unimaginably difficult when one's own family believes their offspring is possessed by evil spirits. This 2008 exposé by Dutch filmmakers Mags Gavan and Joost van der Valk shines an unwanted spotlight on a poor part of Nigeria where children are ostracized, tortured or even murdered after being singled out as witches by religious leaders. But it also highlights the work of two men who are doing all they can to save them from certain doom. — Joe Friedrich

Singer Jill Scott and Quinton Aaron (The Blind Side) guest star in this repeat from March as the sister and nephew of a disabled woman who was beaten and raped. They are not only her relatives but also her caregivers, and those roles put them at the top of the suspect list as Benson and Stabler try to get the victim to tell them what happened. This is no easy task, since the victim's advanced multiple sclerosis renders her unable to speak. — Jennifer Sankowski
