Answer the following question given this paragraph: In science, a theory has been repeatedly shown to be true. A theory is supported by many observations. However, a theory may be disproved if conflicting data is discovered. Many important theories have been shown to be true by many observations and experiments and are extremely unlikely to be disproved. These include the theory of plate tectonics and the theory of evolution. Q: What does a theory need to be supported by? A:
OPTIONS:
- facts
- peer reviewed journals
- scientists
- many observations

Answer: many observations

Question: Answer the following question given this paragraph: The nuclear envelope is a double membrane of the nucleus that encloses the genetic material. It separates the contents of the nucleus from the cytoplasm. The nuclear envelope is made of two phospholipid bilayers, an inner membrane and an outer membrane. The outer membrane is continuous with the rough endoplasmic reticulum. Many tiny holes called nuclear pores are found in the nuclear envelope. These nuclear pores help to regulate the exchange of materials (such as RNA and proteins) between the nucleus and the cytoplasm. Q: What is a double membrane of the nucleus that encloses the genetic material? A:
OPTIONS:
- the complex envelope
- the cell wall
- the nuclear compression
- the nuclear envelope
Answer: the nuclear envelope

input with options: Answer the following question given this paragraph: Caecilians are most closely related to salamanders. As you can see from Figure below , they have a long, worm-like body without legs. Caecilians evolved from a tetrapod ancestor, but they lost their legs during the course of their evolution. Q: What ancestors did caecillians evolve from? A:
OPTIONS:
- ornithopod
- arthropod
- hominid
- tetrapod
output: tetrapod

Q: Answer the following question given this paragraph: - For lenses, the distance from the center of the lens to the focus is . Focal lengths are positive for converging lens and negative for diverging lens. The distance from the center of the lens to the object in question is , where distances to the left of the lens are positive in sign. The distance from the center of the lens to the image is . This number is positive for real images (formed to the right of the lens), and negative for virtual images (formed to the left of the lens). Q: What lengths are positive for converging lens and negative for diverging lens? A:

OPTIONS:
- light lengths
- wavelengths
- differential lengths
- focal lengths

A: focal lengths

input: OPTIONS:
- landslide
- evaporate
- drop
- creep Now, answer this question: Answer the following question given this paragraph: Creep is the very slow movement of rock and soil down a hillside. Creep occurs so slowly you can't see it happening. You can only see the effects of creep after years of movement. This is illustrated in Figure below . The slowly moving ground causes trees, fence posts, and other structures on the surface to tilt downhill. Q: What is the very slow movement of rock and soil down a hillside? A:
A:
output: creep

Question: Answer the following question given this paragraph: Many enzymes are simple proteins consisting entirely of one or more amino acid chains. Other enzymes contain a nonprotein component called a cofactor that is necessary for the enzyme's proper functioning. There are two types of cofactors: inorganic ions [e. , zinc or Cu(I) ions] and organic molecules known as coenzymes. Most coenzymes are vitamins or are derived from vitamins. Q: Many enzymes are simple proteins consisting entirely of one or more of these? A:
OPTIONS:
- alkali acid chains
- interaction acid chains
- proteins acid chains
- amino acid chains
Answer:
amino acid chains
