TASK DEFINITION: In this task you will be given a passage and a yes/no question based on the passage. You should answer the question using the information from the passage.
PROBLEM: passage: Running is a method of terrestrial locomotion allowing humans and other animals to move rapidly on foot. Running is a type of gait characterized by an aerial phase in which all feet are above the ground (though there are exceptions). This is in contrast to walking, where one foot is always in contact with the ground, the legs are kept mostly straight and the center of gravity vaults over the stance leg or legs in an inverted pendulum fashion. A characteristic feature of a running body from the viewpoint of spring-mass mechanics is that changes in kinetic and potential energy within a stride occur simultaneously, with energy storage accomplished by springy tendons and passive muscle elasticity. The term running can refer to any of a variety of speeds ranging from jogging to sprinting.
 question: do both feet leave the ground when running?

SOLUTION: Yes

PROBLEM: passage: Historically, the dunk contest drew some mild criticisms. One is that players who often compete in these contests are seen as dunkers only (with the obvious exceptions of Michael Jordan, Kobe Bryant, and Julius Erving), which is why notable high flying athletes like Shawn Marion and LeBron James have sometimes refused to participate. High-profile players such as Dwyane Wade and Charles Barkley have also declined to participate citing it as an unnecessary risk to injury. In the 2000 NBA Slam Dunk Contest, Tracy McGrady injured his wrist while performing a dunk. Also in the 1995 NBA Slam Dunk Contest, Tony Dumas hurt his knee while performing his ``Texas Twister'' dunk. Although a longtime critic, LeBron James said he would perform in the 2010 Slam Dunk Contest. This decision was made after watching the 2009 dunk contest when Dwight Howard and Nate Robinson went at it. However, he withdrew his statement once the All-Star Weekend came around.
 question: has lebron james ever been in the dunk contest?

SOLUTION: No

PROBLEM: passage: In mathematics, the complex conjugate root theorem states that if P is a polynomial in one variable with real coefficients, and a + bi is a root of P with a and b real numbers, then its complex conjugate a − bi is also a root of P.
 question: if a + bi is a complex zero of a polynomial with real coefficients then so is its a − bi?

SOLUTION:
Yes
