Answer the following question given this paragraph: You know that friction produces heat. That's why rubbing your hands together makes them warmer. But do you know why the rubbing produces heat? Friction causes the molecules on rubbing surfaces to move faster, so they have more heat energy. Heat from friction can be useful. It not only warms your hands. It also lets you light a match (see Figure below ). On the other hand, heat from friction can be a problem inside a car engine. It can cause the car to overheat. To reduce friction, oil is added to the engine. Oil coats the surfaces of moving parts and makes them slippery so there is less friction. Q: Friction causes the molecules on rubbing surfaces to move faster, which produces what? A:
OPTIONS:
- life
- precipitation
- cold
- heat

Answer: heat

Question: Answer the following question given this paragraph: Single-celled organisms do not need blood. They obtain nutrients directly from and excrete wastes directly into their environment. The human organism cannot do that. Our large, complex bodies need blood to deliver nutrients to and remove wastes from our trillions of cells. The heart pumps blood throughout the body in a network of blood vessels. Together, these three componentsblood, heart, and vesselsmakes up the cardiovascular system. This chapter focuses on the medium of transport: blood. Q: What type of organisms do not need blood? A:
OPTIONS:
- cold-blooded
- vertebrate
- marine
- single-celled
Answer: single-celled

input with options: Answer the following question given this paragraph: A dipole occurs when two opposite charges are separated by some amount of distance. We have already seen dipoles in the form of polar bonds. For example, each O-H bond in water is an example of a dipole; the partial positive charge on hydrogen is separated from the partial negative charge on oxygen by the length of the bond. A molecular dipole is the geometric sum of all the individual bond dipoles in a molecule. In order for a molecule to have a dipole, it must have at least one polar bond. However, not all molecules with polar bonds have an overall molecular dipole. Sometimes the dipoles within a molecule will effectively cancel each other out, giving a zero net molecular dipole. This is often seen in symmetrical molecules. Q: What occurs when two opposite charges are separated by some amount of distance? A:
OPTIONS:
- particle
- radioactivity
- diffusion
- dipole
output: dipole

Q: Answer the following question given this paragraph: Raptors such as hawks and owls are carnivores. They hunt and eat mammals and other birds. Vultures are scavengers. They eat the remains of dead animals, such as roadkill. Aquatic birds generally eat fish or water plants. Perching birds may eat insects, fruit, honey, or nectar. Many fruit-eating birds play a key role in seed dispersal, and some nectar-feeding birds are important pollinators. Q: What term is used to describe birds that hunt, eat mammals, and other birds? A:

OPTIONS:
- warriors
- consumers
- predators
- raptors

A: raptors

input: OPTIONS:
- fimbriae
- biofilm
- endothelium
- pellicle Now, answer this question: Answer the following question given this paragraph: Cell Structure The cells of protists are among the most elaborate of all cells. Most protists are microscopic and unicellular, but some true multicellular forms exist. A few protists live as colonies that behave in some ways as a group of free-living cells and in other ways as a multicellular organism. Still other protists are composed of enormous, multinucleate, single cells that look like amorphous blobs of slime, or in other cases, like ferns. In fact, many protist cells are multinucleated; in some species, the nuclei are different sizes and have distinct roles in protist cell function. Single protist cells range in size from less than a micrometer to three meters in length to hectares. Protist cells may be enveloped by animal-like cell membranes or plant-like cell walls. Others are encased in glassy silica-based shells or wound with pellicles of interlocking protein strips. The pellicle functions like a flexible coat of armor, preventing the protist from being torn or pierced without compromising its range of motion. Q: What functions like a flexible coat of armor, preventing the protist from being torn or pierced without compromising its range of motion? A:
A:
output: pellicle

Question: Answer the following question given this paragraph: Today, remote-control vehicles, called remotely operated vehicles (ROVs) go to the deepest ocean floor. They don't have any people on board. However, they carry devices that record many measurements. They also collect sediments and take photos. Q: What type of vehicles is able to go to the deepest ocean floor? A:
OPTIONS:
- off road vehicles
- all-terrain vehicles
- autonomous controlled airplanes
- remote-control vehicles
Answer:
remote-control vehicles
