Problem:OPTIONS:
- metallic mass
- real mass
- major mass
- atomic mass

Answer the following question given this paragraph: You can see how Mendeleev organized the elements in Figure below . From left to right across each row, elements are arranged by increasing atomic mass. Mendeleev discovered that if he placed eight elements in each row and then continued on to the next row, the columns of the table would contain elements with similar properties. He called the columns groups . They are sometimes called families, because elements within a group are similar but not identical to one another, like people in a family. Q: In the periodic table, elements are arranged from left to right according to what property? A:
****
A: atomic mass

Answer the following question given this paragraph: Earth and Moon orbit each other. This Earth-Moon system orbits the Sun in a regular path ( Figure below ). Gravity is the force of attraction between all objects. Gravity keeps the Earth and Moon in their orbits. Earth's gravity pulls the Moon toward Earth's center. Without gravity, the Moon would continue moving in a straight line off into space. Q: What keeps the earth orbiting the sun? A:
OPTIONS:
- strong nuclear force
- magnetic force
- weak nuclear force
- gravity
gravity

Answer the following question given this paragraph: A catalyst works by providing a lower energy pathway from reactants to products. The use of a catalyst involves intermediate reactions which have lower activation complexes than the original reaction. On a simplified reaction energy diagram, this can be thought of as lowering the activation energy for a given transformation. If the activation energy of a reaction is decreased, more collisions will have enough energy to overcome this lower barrier, so the reactant-to-product transformation will occur more frequently. As a result, the overall reaction rate will be higher than for an identical reaction with a larger activation energy barrier. Q: What works by providing a lower energy pathway from reactants to products? A:
OPTIONS:
- thermodynamics
- hormones
- magnetism
- catalyst

Answer: catalyst

Question: Answer the following question given this paragraph: Earth is a round, three-dimensional ball. In a small area, Earth looks flat, so it is not hard to make accurate maps of a small place. When mapmakers want to map the round Earth on flat paper, they use projections. What happens if you try to flatten out the skin of a peeled orange? Or if you try to gift wrap a soccer ball? To flatten out, the orange peel must rip, and its shape must become distorted. To wrap a round object with flat paper requires lots of extra cuts and folds. A projection is a way to represent Earth's curved surface on flat paper ( Figure below ). Q: What method is used to map the earth on flat paper? A:
OPTIONS:
- calculations
- forecasts
- surveying
- projections
Answer: projections

input with options: Answer the following question given this paragraph: Q: The volume of blood each ventricle pumps per minute is called what? A:
OPTIONS:
- trauma output
- blood output
- brain output
- cardiac output
output: cardiac output

Problem: OPTIONS:
- vacuum waves
- gas waves
- energy waves
- body waves
Q: Answer the following question given this paragraph: Body waves travel through the body of a planet. Surface waves travel along the surface. Q: What type of waves travel through the body of a planet? A:
Answer:
body waves
