2. Any serious policy discussion about acceptable levels of risk in
connection with explosions is not well served if the participants fail to use

two terms, “explosion” is the one that should be used throughout discussions of
Which of the following is an assumption on which the argument above depends?
(A) In the kind of discussion at issue, the advantages of desirable reactions to

reactions to that term.
(B) The phrase “energetic disassembly” has not so far been used as a substitute
for the word “explosion” in the kind of discussion at issue.
(C) In any serious policy discussion, what is said by the participants is more

describing a controlled rather than an accidental explosion
