4. To construct a sound argument, one must anticipate the evidence needed to
support a claim. For Appendix 2, you can choose between two claims: 1) yes, the
eggs in the current breeding season have less yolk than expected, or 2) no, the
eggs in the current breeding season do not have less yolk than expected.
To that end, select the figure that best illustrates what one should expect to

expected.
In each of the three figures below, the y-axis represents the mean yolk mass, with
higher values indicating a greater yolk mass and lower values indicating less yolk
mass. The x-axis compares two periods: past breeding seasons and the current
breeding season.
