input with options: Answer the following question given this paragraph: An element is a pure substance. It cannot be separated into any other substances. There are more than 90 different elements that occur in nature. Some are much more common than others. Hydrogen is the most common element in the universe. Oxygen is the most common element in Earth's crust. Figure below shows other examples of elements. Still others are described in the video below. Q: What element is the most common element in the universe? A:
OPTIONS:
- carbon
- helium
- nitrogen
- hydrogen
output: hydrogen

Q: Answer the following question given this paragraph: An organ is a structure composed of two or more types of tissues that work together to do a specific task. Most modern plants have several organs that help them survive and reproduce in a variety of habitats. Major organs of most plants include roots, stems, and leaves. These and other plant organs generally contain all three major tissue types. Q: What do you call a structure composed of two or more types of tissues that work together to do a specific task? A:

OPTIONS:
- cell
- marrow
- system
- organ

A: organ

input: OPTIONS:
- cell rejection
- anomalies
- mutation
- allergies Now, answer this question: Answer the following question given this paragraph: Allergies occur when the immune system attacks harmless substances that enter the body from the outside. Q: What occurs when the immune system attacks harmless substances that enter the body from the outside? A:
A:
output: allergies

Answer the following question given this paragraph: The hypothalamus is actually part of the brain (see Figure below ), but it also secretes hormones . Some of its hormones "tell" the pituitary gland either to secrete or to stop secreting its hormones. In this way, the hypothalamus provides a link between the nervous and endocrine systems. The hypothalamus also produces hormones that directly regulate body processes. These hormones travel to the pituitary gland, which stores them until they are needed. The hormones include antidiuretic hormone and oxytocin. Q: Which part of the brain secretes hormones that tell the pituitary gland either to secrete or to stop secreting its hormones? A:

OPTIONS:
- cerebrum
- hippocampus
- thalamus
- hypothalamus

Answer: hypothalamus

Problem: OPTIONS:
- water
- chlorophyll
- air
- light
Q: Answer the following question given this paragraph: every organism uses to power its metabolism. In brief, the energy of sunlight is captured and used to energize electrons, which are then stored in the covalent bonds of sugar molecules. How long lasting and stable are those covalent bonds? The energy extracted today by the burning of coal and petroleum products represents sunlight energy captured and stored by photosynthesis almost 200 million years ago. Plants, algae, and a group of bacteria called cyanobacteria are the only organisms capable of performing photosynthesis (Figure 8.2). Because they use light to manufacture their own food, they are called photoautotrophs (literally, "self-feeders using light"). Other organisms, such as animals, fungi, and most other bacteria, are termed heterotrophs ("other feeders"), because they must rely on the sugars produced by photosynthetic organisms for their energy needs. A third very interesting group of bacteria synthesize sugars, not by using sunlight's energy, but by extracting energy from inorganic chemical compounds; hence, they are referred to as chemoautotrophs. Q: Photoautotrophs use what energy source to self-manufacture their own food? A:
Answer: light

Answer the following question given this paragraph: Chemical cells are found in batteries. They produce voltage by means of chemical reactions. Chemical cells have two electrodes, which are strips of different materials, such as zinc and carbon. The electrodes are suspended in an electrolyte. This is a substance that contains free ions, which can carry electric current. The electrolyte may be either a paste, in which case the cell is called a dry cell, or a liquid, in which case the cell is called a wet cell. Flashlight batteries contain dry cells. Car batteries contain wet cells. Q: Batteries produce voltage through what type of reaction? A:

OPTIONS:
- liquid
- non-chemical
- thermal
- chemical

Answer:
chemical
