Problem: OPTIONS:
- strip mine
- fracking
- gold mine
- open-pit mine
Q: Answer the following question given this paragraph: As the name suggests, open-pit mining creates a big pit from which the ore is mined. Figure below shows an open-pit diamond mine in Russia. The size of the pit grows as long as the miners can make a profit. Strip mines are similar to open-pit mines, but the ore is removed in large strips. A quarry is a type of open-pit mine that produces rocks and minerals that are used to make buildings and roads. Q: A quarry, which produces rocks and minerals used to make buildings and roads, is an example of what type of mine? A:
Answer: open-pit mine

Problem:OPTIONS:
- frictional forces
- tension forces
- hydrodynamic forces
- centripetal forces

Answer the following question given this paragraph: In the absence of a net force, objects move in a straight line. If they turn that is, if their velocity changes, even only in direction there must be an applied force. Forces which cause objects to turn around continuously in a circle are known as centripetal forces. When an object moves in a circle its velocity at any particular instant points in a direction tangent to the circle. The acceleration points towards the center of the circle, and so does the force acting on it. This is only natural, when you think about it if you feel a force pushing you towards your left as you walk forward, you will walk in a circle, always turning left. Q: Forces which cause objects to turn around continuously in a circle are known as? A:
****
A: centripetal forces

Answer the following question given this paragraph: A: The copper has become tarnished. The tarnishalso called patinais a compound called copper carbonate, which is green. Copper carbonate forms when copper undergoes a chemical reaction with carbon dioxide in moist air. The green patina that forms on copper actually preserves the underlying metal. That's why it's not removed from the statue. Some people also think that the patina looks attractive. Q: What compound gives tarnished copper it's green color? A:
OPTIONS:
- bronze
- zinc
- brass
- copper carbonate
copper carbonate

Answer the following question given this paragraph: Sulfur oxides are produced when sulfur and oxygen combine. This happens when coal that contains sulfur burns. Q: What is produced when sulfur and oxygen combine? A:
OPTIONS:
- Acidic oxides
- hydrogen oxide
- Basic Oxides
- sulfur oxide

Answer: sulfur oxide

Question: Answer the following question given this paragraph: The Role of Blood in the Body Blood, like the human blood illustrated in Figure 40.5 is important for regulation of the body's systems and homeostasis. Blood helps maintain homeostasis by stabilizing pH, temperature, osmotic pressure, and by eliminating excess heat. Blood supports growth by distributing nutrients and hormones, and by removing waste. Blood plays a protective role by transporting clotting factors and platelets to prevent blood loss and transporting the disease-fighting agents or white blood cells to sites of infection. Q: Blood helps maintain homeostasis by stabilizing ph, temperature, osmotic pressure, and by eliminating this? A:
OPTIONS:
- toxins
- acid
- water
- excess heat
Answer: excess heat

A:
output:
