input with options: Answer the following question given this paragraph: Summary Each atom of an element contains the same number of protons, which is theatomic number (Z). Neutral atoms have the same number of electrons and protons. Atoms of an element that contain different numbers of neutrons are calledisotopes. Each isotope of a given element has the same atomic number but a different mass number (A), which is the sum of the numbers of protons and neutrons. The relative masses of atoms are reported using the atomic mass unit(amu), which is defined as one-twelfth of the mass of one atom of carbon-12, with 6 protons, 6 neutrons, and 6 electrons. The atomic mass of an element is the weighted average of the masses of the naturally occurring isotopes. When one or more electrons are added to or removed from an atom or molecule, a charged particle called an ion is produced, whose charge is indicated by a superscript after the symbol. Q: What do neutral atoms have the same number of? A:
OPTIONS:
- toxins and protons
- gases and protons
- Measure and electrons
- electrons and protons
output: electrons and protons

Q: Answer the following question given this paragraph: Atomic Number In the 1910s, experiments with X rays led to this useful conclusion: the magnitude of the positive charge in the nucleus of every atom of a particular element is the same. In other words, all atoms of the same element have the same number of protons. Furthermore,. Q: All atoms of the same element have the same number of what? A:

OPTIONS:
- electrons
- molecules
- charge
- protons

A: protons

input: OPTIONS:
- stomach
- large intestine
- rectum
- small intestine Now, answer this question: Answer the following question given this paragraph: The ileum is the third part of the small intestine. A few remaining nutrients are absorbed here. Like the jejunum, the inner surface of the ileum is covered with villi that increase the surface area for absorption. Q: The site of some nutrient absorption, the ileum is the third part of what digestive organ? A:
A:
output: small intestine

Answer the following question given this paragraph: Solar cells convert the energy in sunlight to electrical energy. Solar cells are also called photovoltaic (PV) cells because they use light ( photo- ) to produce voltage ( -voltaic ). Solar cells contain a material such as silicon that absorbs light energy. The energy knocks electrons loose so they can flow freely and produce a difference in electric potential energy, or voltage. The flow of electrons creates electric current. Solar cells have positive and negative contacts, like the terminals in chemical cells. If the contacts are connected with wire, current flows from the negative to positive contact. The Figure below and following URL show how a solar cell works. http://www. suntreksolar. com/solarElectricity/howCellsWork. asp. Q: Solar cells convert the energy in sunlight to what type of energy? A:

OPTIONS:
- active energy
- radical energy
- stellar energy
- electrical energy

Answer: electrical energy

Problem: OPTIONS:
- viviparous
- herbivores
- marsupial
- monotremes
Q: Answer the following question given this paragraph: Mammals have separate sexes and reproduce sexually. They produce eggs or sperm and must mate in order for fertilization to occur. A few mammals are oviparous. They lay eggs, which later hatch. These mammals are called monotremes. Most mammals are viviparous and give birth to live young. These mammals are either placental mammals or marsupials. Placental mammals give birth to relatively large and well-developed fetuses. Marsupials give birth to smaller, less-developed embryos. In both placental and marsupial mammals, the young grow and develop inside the mother's body in an organ called the uterus. At birth, they pass through a tube-like organ called the birth canal, or vagina. Q: Mammals that lay eggs are called what? A:
Answer: monotremes

Answer the following question given this paragraph: A common disorder of the ovaries is an ovarian cyst . A cyst is a sac filled with fluid or other material. An ovarian cyst is usually harmless, but it may cause pain. Most cysts slowly disappear and do not need treatment. Very large or painful cysts can be removed with surgery. Q: What is the term for a sac filled with fluid or other material? A:

OPTIONS:
- blister
- lesion
- tumor
- cyst

Answer:
cyst
