What is the most similar meaning of the word maximum as per the article?

The word "maximum" refers to the highest or greatest amount, level, or degree that something can achieve or contain. In this context, it is important to identify that "greatest" captures that essence perfectly, conveying the idea of an upper limit or the most that can be reached.

The other options do not align with the meaning of "maximum." For instance, "minimum" signifies the lowest limit, which is directly opposite to maximum. "Average" indicates a middle value, which also does not reflect the extremity of maximum. Lastly, "moderate" suggests a middle ground rather than the highest point, reinforcing why "greatest" is the most accurate synonym for maximum in this context.
