Question 21

Re- implies duplication or repetition when attached to a root word.

The prefix "Re-" indicates the action of doing something again or returning to a previous state, thus implying duplication or repetition.

A) Un-

The prefix "Un-" signifies negation or the opposite of a root word. For example, "unknown" means not known, which does not suggest duplication or repetition.

B) Dis-

"Dis-" conveys a sense of removal or negation from the root word. An example is "disagree," which indicates a lack of agreement rather than any form of repetition or duplication.

C) Re-

"Re-" is the correct answer as it explicitly denotes the action of repeating or doing something again, such as in "redo," which means to do again. This prefix is fundamentally associated with the concept of duplication.

D) In-

The prefix "In-" typically denotes negation or the absence of a quality, as seen in "incomplete," which indicates something that is not whole, rather than suggesting any form of repetition.

Conclusion

The prefix "Re-" is definitively the correct choice as it explicitly implies duplication or repetition, as demonstrated in various examples. All other options, including "Un-," "Dis-," and "In-," focus on negation or the absence of qualities, making them unsuitable for the context of indicating repetition.
