Answer:
A) cyclic and predictable
Explanation:
The graph shows changes in the water levels (in feet, ft). The water cycle consists of water that evaporates from the surface (land and sea) and subsequently returns in form of rain and/or snow. In general, water levels may be unpredictable in short term but predictable in the long term. The graph shows that this process is cyclic because it is regularly patterned and also occurs in regular intervals (therefore being predictable).
Because evolution has not been explicitly proven. There has been some evidence, but there is not enough real proof to support this. Even the man who invented the theory of evolution ended up not believing in his own theory at the time of his death. Overall, the premise of evolution is built on an unstable rock, a theory.
