这道题可以解释下么

问题如下：

Scott asks Bird to evaluate the impact of yield curve movements on fixed-income securities. Bird constructs a yield curve factor model that describes three independent yield curve movements. The yield curve movements are shown in Exhibit 2.

Using the information provided in Exhibit 2, the movements characterized by Factor 1, Factor 2, and Factor 3, respectively, are most likely:

选项：

A.

level, steepness, and curvature.

B.

curvature, level, and steepness.

C.

steepness, curvature, and level.

解释：

Correct Answer: C

Factor 1, Factor 2, and Factor 3 represent movements in steepness, curvature, and level, respectively. Factor 1 represents a change in steepness in the yield curve because the changes in yield increase through each maturity point. Factor 2 represents a change in curvature in the yield curve because the changes in the front end and back end of the curve are different from the change in the middle of the curve. Factor 3 represents a change in level in the yield curve because the changes in yield are essentially the same across all maturity points.
