Questions 1–2 are based on the following paragraphs.
while some artists paint with watercolors, others prefer oil. the two types of paints are similar in some ways. both are used for creating beautiful paintings, and both use similar pigments (a pigment is a powdered substance that gives paint its color). for example, the powder from an iron mineral called ocher is used to make yellow ocher. a metal called cadmium produces a bright red pigment.
while artists sometimes use both kinds of paints, there are important differences between oils and watercolors. first, they use a different medium. watercolor pigments come in tubes and are mixed with purified water. however, the colors can also be found in small pads of dry pigment to which water must be added. oil paint is made by mixing pigments with linseed oil, made from plants. second, watercolors dry very quickly on paper, while oil paint dries very slowly. third, watercolors can be made stronger or weaker by the amount of water added, while oil paints are altered by adding either linseed oil or turpentine.
