Question

refer to figure 4-3. starting with initial curves $d_0$ and $s_0$, which movement is consistent with a successful advertising campaign that claims wool keeps you warm?
a movement from point a to point h
a movement from point a to point b
a movement from point a to point d
a movement from point a to point f

Explanation:

A successful advertising campaign highlighting wool's warmth increases consumer demand for wool. In supply-demand graphs, a demand increase shifts the demand curve rightward (from $D_0$ to $D_1$), while supply remains unchanged ($S_0$). This moves the equilibrium point from A (intersection of $D_0$ and $S_0$) to F (intersection of $D_1$ and $S_0$). Other options reflect supply shifts or demand decreases, which do not match the scenario.

Answer:

a movement from Point A to Point F
