Which term means 'The amount left over' as a noun reference?

• A. Residual
• B. Recessive
• C. Status
• D. Site

Answer: (A)

The main idea here is identifying a noun that describes what remains after the rest has been used or removed. The word that fits this sense is residual. As a noun, residual refers to the amount left over, the remainder, or what remains after other parts have been accounted for. You can see this in everyday uses like leftover funds or the leftover portion after calculations, and in statistics where residuals are the differences between observed values and those predicted by a model, i.e., what remains unexplained by the model. The other terms don’t capture that same sense. Recessive is a genetics term describing an allele that is masked by another; status refers to a person’s or thing’s position or condition, not the leftover amount; site simply means a location or place.
