Answer the following question given this paragraph: One of the reasons the periodic table is so useful is because its structure allows us to qualitatively determine how some properties of the elements vary versus their position on the periodic table. The variation of properties versus position on the periodic table is called periodic trends. There is no other tool in science that allows us to judge relative properties of a class of objects like this, which makes the periodic table a very useful tool. Many periodic trends are general. There may be a few points where an opposite trend is seen, but there is an overall trend when considered across a whole row or down a whole column of the periodic table. The first periodic trend we will consider atomic radius. The atomic radius is an indication of the size of an atom. Although the concept of a definite radius of an atom is a bit fuzzy, atoms behave as if they have a certain radius. Such radii can be estimated from various experimental techniques, such as the x-ray crystallography of crystals. As you go down a column of the periodic table, the atomic radii increase. This is because the valence electron shell is getting a larger and there is a larger principal quantum number, so the valence shell lies physically farther away from the nucleus. This trend can be summarized as follows:. Q: Snippet 2: one of the reasons the periodic table is so useful is because its structure allows us to qualitatively determine how some properties of the elements vary versus their position on the periodic table. the variation of properties versus position on the periodic table is called what? A:
****
A: periodic trends

Answer the following question given this paragraph: Many people have problems with their vision , or ability to see. Often, the problem is due to the shape of the eyes and how they focus light. Two of the most common vision problems are nearsightedness and farsightedness, which you can read about below. You may even have one of these vision problems yourself. Usually, the problems can be corrected with contact lenses or lenses in eyeglasses. In many people, they can also be corrected with laser surgery, which reshapes the outer layer of the eye. For a video about vision problems, go to this URL: http://www. youtube. com/watch?v=ekSGbXt4XdI. Q: What are the two most common vision problems? A:
OPTIONS:
- colorblindness and farsightedness
- glaucoma and nearsightedness
- colorblindness and nearsightedness
- nearsightedness and farsightedness
nearsightedness and farsightedness

Answer the following question given this paragraph: We can see two general types of effects when humans are exposed to radiation. Low-level exposure can lead to development of cancer. The regulatory processes regulating cell growth are disrupted, leading to uncontrolled growth of abnormal cells. Acute exposure can produce nausea, weakness, skin burns, and internal tissue damage. Cancer patients receiving radiation therapy experience these symptoms, but the radiation is targeted to a specific site in the body so that the damage is primarily to the cancer cells and the patient is able to recover from the exposure. Q: Low-level exposure of humans to radiation can cause what? A:
OPTIONS:
- illness
- coughing
- bleeding
- cancer

Answer: cancer

Question: Answer the following question given this paragraph: The only light that people can see is called visible light . This light consists of a very narrow range of wavelengths that falls between infrared light and ultraviolet light. Within the visible range, we see light of different wavelengths as different colors of light, from red light, which has the longest wavelength, to violet light, which has the shortest wavelength (see Figure below ). When all of the wavelengths of visible light are combined, as they are in sunlight, visible light appears white. You can learn more about visible light at this URL: http://www. youtube. com/watch?v=PMtC34pzKGc . Q: What do we call the only light that people can see? A:
OPTIONS:
- wave light
- spectral light
- natural light
- visible light
Answer: visible light

input with options: Answer the following question given this paragraph: The cerebrum is divided into a right and left half ( Figure above ). Each half of the cerebrum is called a hemisphere. The two hemispheres are connected by a thick bundle of axons called the corpus callosum . It lies deep inside the brain and carries messages back and forth between the two hemispheres. Q: What is each half of the cerebrum called? A:
OPTIONS:
- demisphere
- a describe
- a biplane
- a hemisphere
output: a hemisphere

Q: Answer the following question given this paragraph: Melting and boiling points are somewhat unique identifiers, especially of compounds. In addition to giving some idea as to the identity of the compound, important information can be obtained about the purity of the material. Q: What is the boiling and freezing point of water in celcius? A:
Answer:
100 degrees c and 0 degrees c
