What term means 'to replace' ?

• A. Mitigate
• B. Substitute
• C. Velocity
• D. Slope

Answer: (B)

Substitute means to replace something by putting another thing in its place. This word is used when one item takes the place of another, like a substitute teacher covering for the regular teacher or substituting honey for sugar in a recipe. That sense of “taking the place of” is exactly what the question is asking for.

Mitigate means to lessen or reduce something harmful or unfavorable, not to replace it. Velocity is the speed of something in a given direction. Slope refers to the incline or the rate of change in a graph, not to replacement.
