Step-by-step explanation:
If the conditions for laborers didn't improve, Cadbury threatened to cease employing children and instead employ a greater number of adults in their factories. This was seen as a way to avoid raising the prices of their products, which could lead to competition from foreign manufacturers and decrease demand in both foreign and domestic markets. The threat was made in order to push for better working conditions and wages for the laborers.
