Input: Article: Various American Idol alumni had success on various record charts around the world; in the U.S. they had achieved 345 number ones on the Billboard charts in its first ten years. According to Fred Bronson, author of books on the Billboard charts, no other entity has ever created as many hit-making artists and best-selling albums and singles. In 2007, American Idol alums accounted for 2.1% of all music sales. Its alumni have a massive impact on radio; in 2007, American Idol had become "a dominant force in radio" according to the president of the research company Mediabase which monitors radio stations Rich Meyer. By 2010, four winners each had more than a million radio spins, with Kelly Clarkson leading the field with over four million spins.

Now answer this question: How many contestants had at least one million radio spins by 2010?

Output: four

Input: Article: With the growing possibility of an Allied invasion in the Balkans, the Axis began to divert more resources to the destruction of the Partisans main force and its high command. This meant, among other things, a concerted German effort to capture Josip Broz Tito personally.

Now answer this question: What type of assault was there in Bosnia?

Output: airborne

Input: Article: To minimize overall weight and size, miniature PM motors may use high energy magnets made with neodymium or other strategic elements; most such are neodymium-iron-boron alloy. With their higher flux density, electric machines with high-energy PMs are at least competitive with all optimally designed singly-fed synchronous and induction electric machines. Miniature motors resemble the structure in the illustration, except that they have at least three rotor poles (to ensure starting, regardless of rotor position) and their outer housing is a steel tube that magnetically links the exteriors of the curved field magnets.

Now answer this question: How do PMs rate against other types of electric motors?

Output:
least competitive
