Answer the following question given this paragraph: The human eye can distinguish only red, green, and blue light. These three colors are the primary colors of light. All other colors of light can be created by combining the primary colors. Secondary colors of lightcyan, yellow, and magentaform when two primary colors combine equally. Q: What three primary colors of light can be distinguished by the human eye? A:
OPTIONS:
- blue, red, orange
- yellow, green, blue
- red, green, yellow
- red, green, blue

Answer: red, green, blue

Question: Answer the following question given this paragraph: Minerals can form various shapes. Polygons are pictured below ( Figure below ). The shapes form as the minerals are broken along their cleavage planes. Cleavage planes determine how the crystals can be cut to make smooth surfaces. People who cut gemstones follow cleavage planes. Diamonds and emeralds can be cut to make beautiful gemstones. Q: The shapes of minerals form as they are broken along what planes? A:
OPTIONS:
- parallel planes
- sedimentary planes
- calcium planes
- cleavage planes
Answer: cleavage planes

input with options: Answer the following question given this paragraph: The respiratory system is the body system that exchanges gases with the outside air. It brings air containing oxygen into the body for the cells. It also releases carbon dioxide from the cells into the air. This exchange of gases is called respiration. Q: Which system in the body exchanges gases with the outside air? A:
OPTIONS:
- immune
- digestive
- vascular
- respiratory
output: respiratory

Q: Answer the following question given this paragraph: The energy that the object gains or loses when traveling through a potential difference is supplied (or absorbed) by the electric field --- there is nothing else there. Therefore, it follows that electric fields contain energy . Q: Where does an object gain or lose it's energy to during travel through a potential difference? A:

OPTIONS:
- particle field
- magnetic field
- wave field
- electric field

A: electric field

Answer the following question given this paragraph: Since the force on a charged particle in a magnetic field is always perpendicular to both its velocity vector and the field vector (check this using the second right hand rule above), a constant magnetic field will provide a centripetal force --- that is, a constant force that is always directed perpendicular to the direction of motion. Two such force/velocity combinations are illustrated above. According to our study of rotational motion, this implies that as long as the particle does not leave the region of the magnetic field, it will travel in a circle. To find the radius of the circle, we set the magnitude of the centripetal force equal to the magnitude of the magnetic force and solve for :. Q: The force on a charged particle in a magnetic field is always perpendicular to both its velocity vector and the? A:
OPTIONS:
- position vector
- track vector
- gravity vector
- field vector
field vector
