Any serious strategy deliberation about tolerable levels of risk in connection with radiation leakage is not well served if the participants fail to use the words “radiation leakage” and use the phrase “undesirable exposure” instead. In fact, the words “radiation leakage” elicit desirable responses, such as a raised level of alertness, whereas the substitute phrase does not. Therefore, of the two terms, “radiation leakage” is the one that should be used throughout deliberations of this sort. Which of the following is an assumption on which the argument above depends?

In the kind of deliberations at issue, the advantages of desirable responses to the term “radiation leakage” outweigh the drawbacks, if any, arising from undesirable responses to that term.

The phrase “undesirable exposure” has not so far been used as a substitute for the word “radiation leakage” in the kind of discussion at issue.

In any serious strategy deliberation, what is said by the participants is more important than how it is put into words.

The only reason that people are using “undesirable exposure” in place of “radiation leakage” is to render any impossible serious policy discussion concerning leakages.

The phrase “undesirable exposure” is not necessarily out of place in describing a controlled rather than an accidental leakage.
