Answer the following question given this paragraph: Scientists make many measurements during experiments. Humans and equipment can make mistakes. Errors are often unavoidable. This is called experimental error . Errors may be due to the equipment being used. In this case, the numbers may be always skewed in one direction. For example, a scale may always measure one-half of an ounce high. People can also make errors. A measurement may not be made precisely. For example, a stopwatch may be stopped too soon or too late. But probably not always in the same direction. To correct for this, many measurements are taken. The measurements are then averaged. Experiments always have a margin of error associated with them. Q: How do you decrease errors in an experiment? Choices: - write about it - ask God - decrease measurements - take many measurements A:
take many measurements

Answer the following question given this paragraph: Introduction Close your eyes and picture a brick wall. What is the basic building block of that wall? A single brick, of course. Like a brick wall, your body is composed of basic building blocks, and the building blocks of your body are cells. Your body has many kinds of cells, each specialized for a specific purpose. Just as a home is made from a variety of building materials, the human body is constructed from many cell types. For example, epithelial cells protect the surface of the body and cover the organs and body cavities within. Bone cells help to support and protect the body. Cells of the immune system fight invading bacteria. Additionally, blood and blood cells carry nutrients and oxygen throughout the body while removing carbon dioxide. Each of these cell types plays a vital role during the growth, development, and day-to-day maintenance of the body. In spite of their enormous variety, however, cells from all organismseven ones as diverse as bacteria, onion, and humanshare certain fundamental characteristics. Q: What are the specialized building blocks of your body? Choices: - tissues - proteins - muscles - cells A:
(Answer)
cells

Answer the following question given this paragraph: The image above is of a copper plate that was made in 1893. The utensil has a great deal of elaborate decoration and the item is very useful. What would have happened if we decided that copper (I) chloride was just as good a material (well, it does have copper in it). The CuCl would end up as a powder when we pounded on it to shape it. Metals behave in unique ways. The bonding that occurs in a metal is responsible for its distinctive properties: luster, malleability, ductility, and excellent conductivity. Q: Luster, malleability, ductility, and conductivity are all properties of which kind of material? Choices: - ores - wood - nonmetals - metals A:
(A).
metals
