Answer the following question given this paragraph: Humans have walked on only two planetary bodies: Earth and the Moon. The footprints the men left behind are the first signs of life ever on the Moon. Scientists learned a great deal about the Moon from the Apollo missions. The samples that were brought back have been studied in laboratories. We know an incredible amount about the Moon because of these samples. Having these rocks radically changed our thinking about the Moon. Q: Which two planetary bodies have humans walked on? A:
OPTIONS:
- Mars and Jupiter
- The Sun and Mars
- Earth and Saturn
- earth and the moon

Answer: earth and the moon

Question: Answer the following question given this paragraph: There are a variety of substances in foods that the body needs. Any substance in food that the body needs is called a nutrient. There are six major types of nutrients: carbohydrates, proteins, lipids, water, minerals, and vitamins. Carbohydrates, proteins, and lipids can be used for energy. Proteins also provide building materials. Proteins, minerals, and vitamins help control body processes. Water is needed by all cells just to stay alive. Q: What do you call any substance in food that the body needs? A:
OPTIONS:
- dietary
- antioxidant
- beneficial
- a nutrient
Answer: a nutrient

input with options: 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
output: field vector

Q: Answer the following question given this paragraph: 2.3 Chemical Reactions Chemical reactions, in which chemical bonds are broken and formed, require an initial investment of energy. Kinetic energy, the energy of matter in motion, fuels the collisions of atoms, ions, and molecules that are necessary if their old bonds are to break and new ones to form. All molecules store potential energy, which is released when their bonds are broken. Four forms of energy essential to human functioning are: chemical energy, which is stored and released as chemical bonds are formed and broken; mechanical energy, which directly powers physical activity; radiant energy, emitted as waves such as in sunlight; and electrical energy, the power of moving electrons. Chemical reactions begin with reactants and end with products. Synthesis reactions bond reactants together, a process that requires energy, whereas decomposition reactions break the bonds within a reactant and thereby release energy. In exchange reactions, bonds are both broken and formed, and energy is exchanged. The rate at which chemical reactions occur is influenced by several properties of the reactants: temperature, concentration and pressure, and the presence or absence of a catalyst. An enzyme is a catalytic protein that speeds up chemical reactions in the human body. Q: What term is used to describe the energy of matter in motion? A:

OPTIONS:
- frictional energy
- gravitational energy
- emotional energy
- kinetic energy

A: kinetic energy

Question: Answer the following question given this paragraph: assigned a unique one-, two-, or three-letter symbol. The names of the elements are listed in the periodic table, along with their symbols, atomic numbers, and atomic masses. The chemistry of each element is determined by its number of protons and electrons. In a neutral atom, the number of electrons equals the number of protons. Q: The chemistry of each element is determined by its number of what? A:
OPTIONS:
- nuclei and neutrons
- protons and neutrons
- electrons and neutrons
- protons and electrons
Answer:
protons and electrons
