input with options: Answer the following question given this paragraph: Where do forces come from? Observations suggest that a force applied to an object is always applied by another object. A hammer strikes a nail, a car pulls a trailer, and a person pushes a grocery cart. Newton realized that forces are not so one-sided. When the hammer exerts a force on the nail, the nail also exerts a force on the hammerafter all, the hammer comes to rest after the interaction. This led to Newton's Third Law of Motion , which states that whenever one object exerts a force on a second object, the second object also exerts a force on the first object, equal in magnitude and opposite in direction. Q: Observations suggest that a force applied to an object is always applied by what? A:
OPTIONS:
- itself
- gravity
- dark matter
- another object
output: another object

Q: Answer the following question given this paragraph: Larger buildings must sway, but not so much that they touch nearby buildings. Counterweights and diagonal steel beams are used to hold down sway. Q: Counterweights and diagonal steel beams are used in buildings to hold down what? A:

OPTIONS:
- traction
- inertia
- gravity
- sway

A: sway

input: OPTIONS:
- negative ions
- similar ion
- constant ion
- positive ion Now, answer this question: Answer the following question given this paragraph: Ionic compounds are named for their positive and negative ions. The name of the positive ion always comes first, followed by the name of the negative ion. For example, positive sodium ions and negative chloride ions form the compound named sodium chloride. Similarly, positive calcium ions and negative chloride ions form the compound named calcium chloride. Q: The name of which ion always comes first? A:
A:
output: positive ion

Answer the following question given this paragraph: The rigid crystals of ionic compounds are brittle. They are more likely to break than bend when struck. As a result, ionic crystals tend to shatter easily. Try striking salt crystals with a hammer and you'll find that they readily break into smaller pieces. You can learn more about the properties of ionic compounds by watching the video at this URL:. Q: When struck, how are the rigid crystals of ionic compounds likely to react? A:

OPTIONS:
- shrink
- bend
- grow
- break

Answer: break

Problem: OPTIONS:
- reptiles
- mammals
- animals
- plants
Q: Answer the following question given this paragraph: Plants have eukaryotic cells with large central vacuoles, cell walls containing cellulose, and plastids such as chloroplasts and chromoplasts. Different types of plant cells include parenchymal, collenchymal, and sclerenchymal cells. The three types differ in structure and function. Q: What living things have cell walls containing cellulose and plastids such as chloroplasts? A:
Answer: plants

Answer the following question given this paragraph: Tight junctions are common at epithelia, which are sheets of cells that form a boundary between a mass of cells and a cavity or space (a lumen ). The membranes of these cells join together, forming a virtually impermeable barrier to fluid. Tight junctions essentially seal adjacent epithelial cells in a narrow layer just beneath their apical surface, which is the portion of the cell exposed to the lumen. The rest of the cell surface is known as the basolateral surface. Tight junctions prevent integral membrane proteins from moving between the apical and basolateral surface, maintaining the properties of those distinct surfaces. For example, receptor-mediated endocytosis occurs at the apical surface and exocytosis at the basolateral surface. Q: What is the term for sheets of cells that form a boundary between a mass of cells and a cavity or space? A:

OPTIONS:
- mucus
- myelin
- ganglion
- epithelia

Answer:
epithelia
