What does it mean to issue a thunderous verbal attack?

To issue a thunderous verbal attack means to express strong, forceful dissent or criticism, often in a way that captures attention and conveys intense emotion. The term "fulminate" specifically refers to the act of shouting forth or vehemently expressing criticism or protest. It carries connotations of a dramatic and thunderous quality, akin to a thunderstorm, which aligns perfectly with the phrasing of the question.

In contrast, the other choices have nuances that do not fully capture the emotive and dramatic quality of "fulminate." For instance, "debate" suggests a structured discussion or argument, which lacks the intensity implied in a thunderous attack. "Condemn" indicates strong disapproval but does not convey the same level of emotional outburst. "Accuse" carries the notion of charging someone with wrongdoing but does not necessarily imply the theatrical intensity of a thunderous verbal assault. Hence, the clarity of "fulminate" as capturing both the forcefulness and the nature of a verbal onslaught makes it the correct choice.
