Research indicates that government warnings can affect buying patterns.

Government warnings linking red meat to poor health and praising chicken as a healthier alternative are likely to increase consumer demand for chicken. With other conditions constant, increased demand shifts the demand curve right, raising the equilibrium price of chicken. Option B (decrease) would occur with decreased demand. Option C (unchanged) ignores the demand shift. Option D (rise, then fall) lacks evidence for a subsequent decline. This question aligns with the Economics category, focusing on demand and price dynamics.
