Input: Article: A servo system differs from some stepper motor applications in that the position feedback is continuous while the motor is running; a stepper system relies on the motor not to "miss steps" for short term accuracy, although a stepper system may include a "home" switch or other element to provide long-term stability of control. For instance, when a typical dot matrix computer printer starts up, its controller makes the print head stepper motor drive to its left-hand limit, where a position sensor defines home position and stops stepping. As long as power is on, a bidirectional counter in the printer's microprocessor keeps track of print-head position.

Now answer this question: What kind of counter keeps track of a print head's position?

Output: bidirectional

Input: Article: While they have played in suburban Foxborough since 1971, the New England Patriots of the National Football League were founded in 1960 as the Boston Patriots, changing their name after relocating. The team won the Super Bowl after the 2001, 2003, 2004, and 2014 seasons. They share Gillette Stadium with the New England Revolution of Major League Soccer. The Boston Breakers of Women's Professional Soccer, which formed in 2009, play their home games at Dilboy Stadium in Somerville.

Now answer this question: What was the original name of the new England patriots?

Output: Boston Patriots

Input: Article: If a heavy piece of pine is compared with a lightweight piece it will be seen at once that the heavier one contains a larger proportion of latewood than the other, and is therefore showing more clearly demarcated growth rings. In white pines there is not much contrast between the different parts of the ring, and as a result the wood is very uniform in texture and is easy to work. In hard pines, on the other hand, the latewood is very dense and is deep-colored, presenting a very decided contrast to the soft, straw-colored earlywood.

Now answer this question: Is white pine easy or difficult to work with because of its texture?

Output:
easy
