input with options: Answer the following question given this paragraph: 2.3 Scientific method The scientific method is not a step by step, linear process. It is an intuitive process, a methodology for learning about the world through the application of knowledge. Scientists must be able to have an "imaginative preconception" of what the truth is. Scientists will often observe and then hypothesize the reason why a phenomenon occurred. They use all of their knowledge and a bit of imagination, all in an attempt to uncover something that might be true. A typical scientific investigation might go like so: You observe that a room appears dark, and you ponder why the room is dark. In an attempt to find explanations to this curiosity, your mind unravels several different hypotheses. One hypothesis might state that the lights are turned off. Another hunch might be that the room's lightbulb has burnt out. Worst yet, you could be going blind. To discover the truth, 10 11 12 13 14. Q: Scientists will often observe and then what the reason why a phenomenon occurred? A:
OPTIONS:
- realize
- normalize
- theorize
- hypothesize
output: hypothesize

Q: Answer the following question given this paragraph: Aerobic respiration , which takes place in the presence of oxygen, evolved after oxygen was added to Earth's atmosphere. This type of respiration is useful today because the atmosphere is now 21% oxygen. However, some anaerobic organisms that evolved before the atmosphere contained oxygen have survived to the present. Therefore, anaerobic respiration , which takes place without oxygen, must also have advantages. Q: Anaerobic respiration takes place without what? A:

OPTIONS:
- nitrogen
- movement
- carbon
- oxygen

A: oxygen

input: OPTIONS:
- bleaching
- remodeling
- eroding
- weathering Now, answer this question: Answer the following question given this paragraph: Weathering changes solid rock into sediments. Sediments are different sizes of rock particles. Boulders are sediments; so is gravel. At the other end, silt and clay are also sediments. Weathering causes rocks at the Earth's surface to change form. The new minerals that form are stable at the Earth's surface. Q: Which process causes rocks at the earth's surface to change form? A:
A:
output: weathering

Answer the following question given this paragraph: A proton is one of three main particles that make up the atom. The other two particles are the neutron and electron. Protons are found in the nucleus of the atom. This is a tiny, dense region at the center of the atom. Protons have a positive electrical charge of one (+1) and a mass of 1 atomic mass unit (amu), which is about 1.67 10 -27 kilograms. Together with neutrons, they make up virtually all of the mass of an atom. For an excellent video on protons and other fundamental particles in atoms, go to this URL:. Q: Which atomic particle has a positive charge? A:

- the electron
- the nucleus
- the neutron
- the proton

Answer: the proton
