Question:

Use the finite-temperature propagators of Section 8.10 for fermions for the single-loop diagram shown in Figure 8.19, and show that you obtain the same Lindhard formula (8.11.10).

Actually, a two-external-leg diagram can also be viewed as a loop, as illustrated in Figure 8.22, if we view the departing particle as the same particle as the incoming particle.
