Problem: OPTIONS:
- warm force
- cool force
- gravity force
- buoyant force
Q: Answer the following question given this paragraph: What explains buoyant force? Recall from the earlier lesson "Pressure of Fluids" that a fluid exerts pressure in all directions but the pressure is greater at greater depth. Therefore, the fluid below an object exerts greater force on the object than the fluid above the object. This is illustrated in Figure below . Buoyant force explains why objects may float in water. No doubt you've noticed, however, that some objects do not float in water. If buoyant force applies to all objects in fluids, why do some objects sink instead of float? The answer has to do with their weight. Q: What force explains why objects may float in water? A:
Answer: buoyant force

Problem:OPTIONS:
- Lungs
- brain
- heart
- blood

Answer the following question given this paragraph: Some diseases affect mainly the blood or its components. They include anemia, leukemia, hemophilia, and sickle-cell disease. Q: Anemia, leukemia, hemophilia, and sickle-cell disease are examples of conditions that primarily affect what? A:
****
A: blood

Answer the following question given this paragraph: Steroid hormones are made of lipids, such as phospholipids and cholesterol. They are fat soluble, so they can diffuse across the plasma membrane of target cells and bind with receptors in the cytoplasm of the cell (see Figure below ). The steroid hormone and receptor form a complex that moves into the nucleus and influences the expression of genes, essentially acting as a transcription factor. Examples of steroid hormones include cortisol and sex hormones. Q: What are steroid hormones made of? A:
OPTIONS:
- water
- amino acid
- organisms
- lipids
lipids

Answer the following question given this paragraph: The inertia of an object depends on its mass. Objects with greater mass also have greater inertia. Think how hard it would be to push a big box full of books, like the one in Figure below . Then think how easy it would be to push the box if it was empty. The full box is harder to move because it has greater mass and therefore greater inertia. Q: What property increases as an object's mass increases, making a full box harder to push than an empty one? A:
OPTIONS:
- weight
- gravity
- magnetism
- inertia

Answer: inertia

Question: Answer the following question given this paragraph: Because the Sun is not solid, it does not have a defined outer boundary. It does, however, have a definite internal structure with identifiable layers ( Figure below ). Since the layers are not solid, the boundaries are fuzzy and indistinct. From inward to outward, the layers are: the core, the radiative zone, and the convection zone. Q: What is the innermost layer of the sun called? A:
OPTIONS:
- Convection Zone
- Chromosphere
- Photosphere
- the core
Answer: the core

input: OPTIONS:
- acids
- atoms
- proteins
- fungi Now, answer this question: Answer the following question given this paragraph: Almost all fungi have a single common ancestor. The earliest fungi may have evolved about 600 million years ago. Fungi colonized land at least 460 million years ago. By 250 million years ago, they may have been the dominant life forms on Earth. Q: Evolving from a single common ancestor, what group of organisms was perhaps the dominant life form on earth 250 million years ago? A:
A:
output:
fungi
