Answer: elastic; inelastic
Step-by-step explanation:
A good is considered (elastic) when producers can quickly supply more or less of it based on changing prices while a good is considered (inelastic) when producers can quickly change how much of it is supplied when prices change.
In an elastic good, a change in price brings about a significant shift in the demand of such good while on the other hand, in an inelastic good, a change in price brings about an insignificant shift in the demand of such good.
