Answer the following question given this paragraph: osmol = M i If more than one solute is present in a solution, the individual osmolarities are additive to get the total osmolarity of the solution. Solutions that have the same osmolarity have the same osmotic pressure. If solutions of differing osmolarities are present on opposite sides of a semipermeable membrane, solvent will transfer from the lower-osmolarity solution to the higher-osmolarity solution. Counterpressure exerted on the highosmolarity solution will reduce or halt the solvent transfer. An even higher pressure can be exerted to force solvent from the high-osmolarity solution to the low-osmolarity solution, a process called reverse osmosis. Reverse osmosis is used to make potable water from saltwater where sources of fresh water are scarce. Q: If solutions of differing osmolarities are present on opposite sides of a semipermeable membrane, solvent will transfer from what to what, in terms of osmolarity of the solution? A:

OPTIONS:
- low to low
- high to high
- high to low
- low to high

Answer: low to high

Answer the following question given this paragraph: Regular physical exercise is important in preventing lifestyle diseases such as cardiovascular disease, some types of cancer, type 2 diabetes, and obesity. Regular exercise also improves the health of the muscular system. Muscles that are exercised are bigger and stronger than muscles that are not exercised. Q: Cardiovascular disease, some types of cancer, type 2 diabetes, and obesity are considered what kind of preventable diseases? A:
OPTIONS:
- environmental diseases
- atmosphere diseases
- age diseases
- lifestyle diseases
lifestyle diseases

Answer the following question given this paragraph: Most mirrors are plane mirrors. A plane mirror has a flat reflective surface and forms only virtual images. The image formed by a plane mirror is also life sized. But something is different about the image compared with the real object in front of the mirror. Left and right are reversed. Look at the man shaving in Figure below . He is using his right hand to hold the razor, but his image appears to be holding the razor in the left hand. Almost all plane mirrors reverse left and right in this way. Q: A plane mirror has a flat reflective surface and forms only which kind of images? A:
OPTIONS:
- enlarged
- spherical
- reduced
- virtual

Answer: virtual

input with options: Answer the following question given this paragraph: Ionic bonds are possible because the elements involved have either donated or accepted one or more electrons. Sodium chloride is formed when each sodium atom donates its single valence electron to a chlorine atom. As a result, both ions have a noble gas configuration, and an attraction is formed between the positive sodium ions and the negative chloride ions. Q: What is formed when each sodium atom donates its single valence electron to a chlorine atom? A:
OPTIONS:
- carbon chloride
- nitrogen chloride
- trioxide chloride
- sodium chloride
output:
sodium chloride
