Which scenario could be represented by this graph?
OA. For some time, the water level of the Humphrey Dam doesn't
change. During a long rain spell, the water level rises, increasing at
a constant rate. After the rain subsides, it levels off again. The x-
axis represents time; the y-axis represents the height of the water
behind the dam.
OB. At first, there is no water behind the Humphrey Dam. As the river is
redirected toward the dam, the water level rises steadily. The x-
axis represents time; the y-axis represents the height of the water
behind the dam.
O C. For some time, heavy rain causes the water level to rise behind the
Humphrey Dam. When the rain subsides, the height of the water
remains high. The x-axis represents time; the y-axis represents the
height of the water behind the dam.
