This figure shows the percentage of daily temperature records set at weather stations across the contiguous 48 states by decade. Record highs (blacks) are compared with record lows (gray). Record Highs and Lows, 1950-2010 According to the graph, which of the following statements is correct?
A. Only two decades reached 50% or more record high temperatures
B. Only one decade reached less than 25% record low temperature records
C. More decades reached greater than 50% of low dally temperature records than reached greater than 50% of daily high temperature records
D. More decades reached greater than 50% of daily high temperature records than reached greater than 50% of low temperature records
D. According to the graph, the correct statement is: "More decades reached greater than 50% of daily high temperature records than reached greater than 50% of low temperature records." The black portion (record highs) of the bars on the graph is larger and covers more decades, indicating that more decades have a greater percentage of record high temperatures than record low temperatures.
Therefore, the Correct Answer is D.
