　　Section C
　　Directions: In this section, you will hear a passage three times. When the passage is read for the first time, you should listen carefully for its general idea. When the passage is read for the second time, you are required to fill in the blanks with the exact words you have just heard. Finally, when the passage is read for the third time, you should check what you have written.

　　Graphics are used in textbooks as part of the language of the discipline, as in math or economics, or as study aids. Authors use graphic aids to（26）and expand on concepts taken up in the text because graphics are yet another way of portraying relationships and（27）connections.
　　Graphics are used extensively in natural sciences and social sciences. Social scientists work with statistics（28）data, and the best way to present these statistics is often in graphic form. Graphics are included- not merely as a means of making the information easier for the student to grasp, but as an integral part of the way social scientists think. Many textbooks,（29）those in economics, contain
appendixes that provide specific information on reading and working with graphic material.
　　Make it a practice to（30）attentively the titles, captions, headings, and other material connected with graphics. These elements（31）and usually explain what you are looking at. When you are examining graphics, the（32）questions to ask are (a.)What is this item about? and (b.)What key idea is the author（33）?
　　One warning: Unless you integrate your reading of graphics with the text, you may make a wrong assumption.（34）, from a chart indicating that 33 percent of firstborn children in a research sample did not feel close to their fathers, you might assume that some dreadful influence was at work on the firstborn children. However, a careful reading of the text（35）that most of the firstborn children in the sample were from single-parent homes in which the father was absent.
