Answer the following question given this paragraph: Q: What type of molecules are found in the hydration shell of a dissolved ion? A:

OPTIONS:
- iron
- carbon
- oxygen
- water

Answer: water

Problem: OPTIONS:
- chloroplasts
- microbial
- carbonate
- chlorophyll
Q: Answer the following question given this paragraph: Bacteria called cyanobacteria are very important. They are bluish green in color (see Figure below ) because they contain chlorophyll. They make food through photosynthesis and release oxygen into the air. These bacteria were probably responsible for adding oxygen to the air on early Earth. This changed the planet's atmosphere. It also changed the direction of evolution. Ancient cyanobacteria also may have evolved into the chloroplasts of plant cells. Q: Cyanobacteria are bluish green in color because they contain what? A:
Answer: chlorophyll

Problem:OPTIONS:
- time
- erosion
- weather
- stress

Answer the following question given this paragraph: When plates are pushed or pulled, the rock is subjected to stress. Stress can cause a rock to change shape or to break. When a rock bends without breaking, it folds. When the rock breaks, it fractures. Mountain building and earthquakes are some of the responses rocks have to stress. Q: Mountain building and earthquakes are some of the responses of rocks when subected to what? A:
****
A: stress

Answer the following question given this paragraph: The concentration of an acid or base can be determined by titration. Q: Titration is a method to determine what in acids or bases? A:
OPTIONS:
- alkalinity
- maturation
- glucose
- concentration
concentration

Answer the following question given this paragraph: Q: Via what process do substance move from one cell to another? A:
OPTIONS:
- reverse transferase
- autolysis
- downregulation
- plasmodesmata

Answer: plasmodesmata

input with options: Answer the following question given this paragraph: A radioisotope has atoms with unstable nuclei. Unstable nuclei naturally decay, or break down. They lose energy and particles and become more stable. As nuclei decay, they gain or lose protons, so the atoms become different elements. This is illustrated in the Figure below . The original, unstable nucleus is called the parent nucleus. After it loses a particle (in this case a type of particle called an alpha particle), it forms a daughter nucleus, with a different number of protons. Q: What has atoms with unstable nuclei? A:
OPTIONS:
- hydrocarbon
- microwaves
- radionuclide
- radioisotope
output:
radioisotope
