TASK DEFINITION: Given a paragraph from a Wikipedia article about some topic, and a question related to the topic, determine whether the question is answerable from the paragraph. If the question is answerable, answer "True", otherwise, answer "False".
PROBLEM: Stepper motors were and still are often used in computer printers, optical scanners, and digital photocopiers to move the optical scanning element, the print head carriage (of dot matrix and inkjet printers), and the platen or feed rollers. Likewise, many computer plotters (which since the early 1990s have been replaced with large-format inkjet and laser printers) used rotary stepper motors for pen and platen movement; the typical alternatives here were either linear stepper motors or servomotors with closed-loop analog control systems. Question: Which of the following is not a device that uses stepper motors: computer printers, digital photocopiers, or servomotors?

SOLUTION: True

PROBLEM: The top ten (eleven in season ten) toured at the end of every season. In the season twelve tour a semi-finalist who won a sing-off was also added to the tour. Kellogg's Pop-Tarts was the sponsor for the first seven seasons, and Guitar Hero was added for the season seven tour. M&M's Pretzel Chocolate Candies was a sponsor of the season nine tour. The season five tour was the most successful tour with gross of over $35 million. Question: What was different from all the previous nine seasons?

SOLUTION: True

PROBLEM: Many minerals provide pigments which have been used in green paints and dyes over the centuries. Pigments, in this case, are minerals which reflect the color green, rather that emitting it through luminescent or phosphorescent qualities. The large number of green pigments makes it impossible to mention them all. Among the more notable green minerals, however is the emerald, which is colored green by trace amounts of chromium and sometimes vanadium. Chromium(III) oxide (Cr2O3), is called chrome green, also called viridian or institutional green when used as a pigment. For many years, the source of amazonite's color was a mystery. Widely thought to have been due to copper because copper compounds often have blue and green colors, the blue-green color is likely to be derived from small quantities of lead and water in the feldspar. Copper is the source of the green color in malachite pigments, chemically known as basic copper(II) carbonate. Question: what is the fourth place mentioned?

SOLUTION:
False
