Researchers have shown that teacher evaluations based on brief viewings of videotapes made by students who were not enrolled in a course correlate well with end-of-the-semester teacher evaluations made by students enrolled in the class. The researchers suggest that the relationship occurs because people can make relatively accurate judgments of affective behavior (e.g., likableness) very quickly because doing so is adaptive. Based on the correlational evidence alone, the researchers' explanation for their findings can best be considered

A. speculative.
B. qualitative.
C. a causal inference.
D. a confirmed hypothesis.
