In each item you are to compare a quantity in Column $1$ with a quantity in Column $2$. Write the letter of the correct answer from these choices: A. The quantity in Column $1$ is greater than the quantity in Column $2$ . B. The quantity in Column $2$ is greater than the quantity in Column $1$ . C. The quantity in Column $1$ is equal to the quantity in Column $2$ . D. The relationship cannot be determined from the given information. Notes: Information centered over both columns refers to one or both of the quantities being compared. A symbol that appears in both columns has the same meaning in each column. All variables represent real numbers. Most figures are not drawn to scale.
