input with options: Answer the following question given this paragraph: Superior Rotation and Inferior Rotation Superior and inferior rotation are movements of the scapula and are defined by the direction of movement of the glenoid cavity. These motions involve rotation of the scapula around a point inferior to the scapular spine and are produced by combinations of muscles acting on the scapula. During superior rotation, the glenoid cavity moves upward as the medial end of the scapular spine moves downward. This is a very important motion that contributes to upper limb abduction. Without superior rotation of the scapula, the greater tubercle of the humerus would hit the acromion of the scapula, thus preventing any abduction of the arm above shoulder height. Superior rotation of the scapula is thus required for full abduction of the upper limb. Superior rotation is also used without arm abduction when carrying a heavy load with your hand or on your shoulder. You can feel this rotation when you pick up a load, such as a heavy book bag and carry it on only one shoulder. To increase its weight-bearing support for the bag, the shoulder lifts as the scapula superiorly rotates. Inferior rotation occurs during limb adduction and involves the downward motion of the glenoid cavity with upward movement of the medial end of the scapular spine. Q: Inferior rotation occurs during limb adduction and involves the downward motion of what? A:
OPTIONS:
- choroidal cavity
- pelvic cavity
- dialysate cavity
- glenoid cavity
output: glenoid cavity

Answer the following question given this paragraph: Smog clouds the city of Los Angeles, California. Visible air pollution in the form of smog is a sign that the air is unhealthy. Q: Smog is a visible form of what? A:

OPTIONS:
- condensation
- water pollution
- oxidation
- air pollution

Answer: air pollution

Problem: OPTIONS:
- oxygen ion
- magnesium ion
- electron
- chloride ion
Q: Answer the following question given this paragraph: The formula unit of sodium chloride dissociates into one sodium ion and one chloride ion. The calcium nitrate formula unit dissociates into one calcium ion and two nitrate ions. This is because of the 2+ charge of the calcium ion. Two nitrate ions, each with a 1 charge are required to make the equation balance electrically. The ammonium phosphate formula unit dissociates into three ammonium ions and one phosphate ion. Note that the polyatomic ions themselves do not dissociate further, but remain intact. Q: The formula unit of sodium chloride dissociates into one sodium ion and one? A:
Answer: chloride ion

OPTIONS:
- bedrock
- humus
- subsoil
- topsoil

Answer:
topsoil
