Many plants have leaves that are larger on one side of their long central axis than the other, a phenomenon known as asymmetrical orientation. University of California, Berkeley biologist Ciera Martinez and colleagues examined several species of grapevines and closely related plants which have leaves that grow in pairs, to see if both leaves in a pair tend to be oriented toward the same side (that is, have more tissue on the same side) or not. They found that in some species, opposite-side orientations are more common than same-side orientations, which can most be shown in the ratio of ______. Which choice most effectively uses data from the table to complete the assertion?

Quantitative evidence: reading the graph the question did not ask about — A choice can describe the chart perfectly and still be the wrong answer. Match the data point to the claim.
