This versatile muscle flexes the leg at the knee and flexes, abducts, and laterally rotates the leg at the hip. This muscle allows us to sit cross-legged. The posterior compartment of the thigh includes muscles that flex the leg and extend the thigh. The three long muscles on the back of the knee are the hamstring group, which flexes the knee. These are the biceps femoris, semitendinosus, and semimembranosus. The tendons of these muscles form the popliteal fossa, the diamond-shaped space at the back of the knee. Q: The three long muscles on the back of the knee are part of which group? A:
OPTIONS:
- synovial joint
- patella
- adductors
- hamstring group
output: hamstring group

Answer the following question given this paragraph: How high or low a sound seems to a listener is its pitch . Pitch, in turn, depends on the frequency of sound waves. Wave frequency is the number of waves that pass a fixed point in a given amount of time. High-pitched sounds, like the sounds of the piccolo in the Figure below , have high-frequency waves. Low-pitched sounds, like the sounds of the tuba Figure below , have low-frequency waves. For a video demonstration of frequency and pitch, go to this URL: http://www. youtube. com/watch?v=irqfGYD2UKw. Q: Dependent on the frequency of sound waves, what term described how high or low a sound seems to a listener? A:

OPTIONS:
- curve
- wavelength

Answer the following question given this paragraph: Birds need a light-weight body in order to stay aloft. Even so, flying is hard work, and flight muscles need a constant supply of oxygen- and nutrient-rich blood. The organ systems of birds are adapted to meet these needs. Q: Why do birds need a light-weight body? A:

OPTIONS:
- for cooling
- water flotation
- food shortages
- to stay aloft

Answer:
to stay aloft
