input with options: Answer the following question given this paragraph: Even compounds with the same number of carbon and hydrogen atoms can have different shapes. These compounds are called isomers . Look at the examples in Figure below . The figure shows the structural formulas of butane and its isomer iso -butane. Both molecules have four carbon atoms and ten hydrogen atoms (C 4 H 10 ), but the atoms are arranged differently. Butane is a straight-chain molecule. Iso -butane is branched. You can see three-dimensional models of these two isomers at the URLs below. You can rotate the molecule models to get a better idea of their shapes. Q: What are compounds with the same number of carbon and hydrogen atoms called? A:
OPTIONS:
- alcohols
- hydrocarbons
- monomers
- isomers
output: isomers

input: OPTIONS:
- diffusion action
- transfusion action
- thermal action
- capillary action Now, answer this question: Answer the following question given this paragraph: Towels soak up liquids like water because the fibers of a towel are made of molecules that are attracted to water molecules. Most cloth towels are made of cotton, and paper towels are generally made from paper pulp. Both consist of long molecules of cellulose that contain many OH groups. Water molecules are attracted to these OH groups and form hydrogen bonds with them, which draws the H2O molecules up the cellulose molecules. The water molecules are also attracted to each other, so large amounts of water are drawn up the cellulose fibers. Capillary action can also occur when one end of a small diameter tube is immersed in a liquid, as illustrated in Figure 10.20. If the liquid molecules are strongly attracted to the tube molecules, the liquid creeps up the inside of the tube until the weight of the liquid and the adhesive forces are in balance. The smaller the diameter of the tube is, the higher the liquid climbs. It is partly by capillary action occurring in plant cells called xylem that water and dissolved nutrients are brought from the soil up through the roots and into a plant. Capillary action is the basis for thin layer chromatography, a laboratory technique commonly used to separate small quantities of mixtures. You depend on a constant supply of tears to keep your eyes lubricated and on capillary action to pump tear fluid away. Q: What can occur when one end of a small diameter tube is immersed in liquid? A:
A:
output: capillary action

Answer the following question given this paragraph: Streak is the color of the powder of a mineral. To do a streak test, you scrape the mineral across an unglazed porcelain plate. The plate is harder than many minerals, causing the minerals to leave a streak of powder on the plate. The color of the streak often differs from the color of the larger mineral sample ( Figure below ). Yellow-gold pyrite has a blackish streak. This blackish streak tells you that the mineral is not gold, because gold has a gold-colored streak. Q: What is the color of the powder of a mineral called? A:

OPTIONS:
- dye
- pigment
- hue
- streak

Answer: streak

Problem: OPTIONS:
- infectious system
- circulatory system
- endocrine system
- nervous system
Q: Answer the following question given this paragraph: Diseases of the nervous system include infections, epilepsy, strokes, and Alzheimer's disease. Injuries include concussions and spinal cord damage that may cause paralysis. Most nervous system diseases can't be prevented, but many nervous system injuries can be prevented by following safe practices. Q: Diseases of this system include epilepsy, strokes, and alzheimer's disease A:
Answer: nervous system
