Which example does NOT contain a redundant modifier?

In this context, the selected example is the most straightforward and clear in its presentation of information. It specifies that "a 75% majority" was required for the bill's approval, which is a precise and necessary detail for understanding how the decision was made. This phrasing does not contain any unnecessary modifiers; instead, it conveys a factual statement effectively.

Each of the other examples includes modifiers that could be seen as superfluous or potentially confusing. For instance, "varied from past experiences" may imply more than is needed and could be simplified for clarity. "Future plans" inherently suggests that the plans are aimed towards the future, and thus the word "future" adds little to the intended meaning. Similarly, in "More than 100 guests," while informative, there could be modifiers that aren't necessary to establish the impact of the attendance.

Thus, the structure of the first example stands out as being concise and free of unnecessary embellishments, aligning with effective communication principles that seek clarity and precision.
