Malian musical traditions are derived from the griots, who are known as "Keepers of Memories". Malian music is diverse and has several different genres. Some famous Malian influences in music are kora virtuoso musician Toumani Diabaté, the late roots and blues guitarist Ali Farka Touré, the Tuareg band Tinariwen, and several Afro-pop artists such as Salif Keita, the duo Amadou et Mariam, Oumou Sangare, and Habib Koité. Dance also plays a large role in Malian culture. Dance parties are common events among friends, and traditional mask dances are performed at ceremonial events.

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
LEDs have also been used as a medium-quality voltage reference in electronic circuits. The forward voltage drop (e.g. about 1.7 V for a normal red LED) can be used instead of a Zener diode in low-voltage regulators. Red LEDs have the flattest I/V curve above the knee. Nitride-based LEDs have a fairly steep I/V curve and are useless for this purpose. Although LED forward voltage is far more current-dependent than a Zener diode, Zener diodes with breakdown voltages below 3 V are not widely available.
What LEDs don't have a very steep I/V curve?
A: unanswerable

Question: In April 2005, Comcast and Time Warner Cable announced plans to buy the assets of bankrupted Adelphia Cable. The two companies paid a total of $17.6 billion in the deal that was finalized in the second quarter of 2006—after the U.S. Federal Communications Commission (FCC) completed a seven-month investigation without raising an objection. Time Warner Cable became the second largest cable provider in the U.S., ranking behind Comcast. As part of the deal, Time Warner and Comcast traded existing subscribers in order to consolidate them into larger geographic clusters.
Is there an answer to this question: How much did the FCC charge Comcast and Time Warner for the investigation?

Answer: unanswerable


QUES: While pursuing his PhD at Princeton, Feynman married his high school sweetheart, Arline Greenbaum (often misspelled "Arlene"), despite the knowledge that she was seriously ill with tuberculosis—an incurable disease at the time. She died in 1945. In 1946, Feynman wrote a letter to her, expressing his deep love and heartbreak, that he kept for the rest of his life. ("Please excuse my not mailing this," the letter concluded, "but I don't know your new address.") This portion of Feynman's life was portrayed in the 1996 film Infinity, which featured Feynman's daughter, Michelle, in a cameo role.

Who played a cameo in a film about Feynman?
What is the answer?
ANS:
Feynman's daughter, Michelle
