题目： In Country X, a ballroom is classified as Category C if it has a ceiling of at least 10 meters. In the graph, each of the 22 Category C ballrooms is represented by two points arranged vertically: one representing the comparison of the height of the ballroom's ceiling to the number of tiles in the ballroom area (black circles), the other representing the comparison of the height of the ballroom's ceiling to the mean length per tile in the ballroom area (red squares). Based on the given information, use the drop-down menus to most accurately complete the following statements about Category C ballrooms in Country X. A) The ballroom with the greatest mean length per ballroom tile has a ceiling height [s[0]] meters. B) There is a [s[1]] correlation between the number of ballroom tiles and the mean length per ballroom tile.

题目： The graph models the hypothetical mass, in kilograms, of a Tyrannosaurus rex up to 30 years of age. Points A, B, and C represent the masses for a Tyrannosaurus rex at ages 12,16, and 20, respectively, according to the model.From each drop-down menu, select the option that creates the most accurate statement based on the information provided.For integer values of the age from 12 to 30, the average (arithmetic mean) mass falls approximately between [s[0]] kilograms.The percent change in the mass from age 12 to age 16 is approximately [s[1]] the percent change in the mass from age 16 to age 20.

题目： The diagram shows, in three column groupings, various divisions of Earth's geological history since its formation approximately 4,600 million years ago. In the leftmost column grouping, the Precambrian eon is subdivided into chronometric eons shown on the far left; but otherwise, in the rest of the graphic, each subsequent column to the right shows the subdivisions of the timeframes to its left. Each of the rightmost two column groupings is a magnification-with additional information-of a portion of the grouping directly to its left.Fill each blank using the drop-down menu to create the most accurate statement on the basis of the information provided.The Miocene epoch spans closest to [s[0]] of the era of which it is a part.According to the diagram the beginning of the [s[1]] marks the onset of a new eon, era, and period in geological history.
