What does the term 'tirade' refer to?

The term 'tirade' refers specifically to a lengthy, intense speech or discourse characterized by anger and critical sentiment. It often involves a speaker expressing strong emotions, usually in a vehement or forceful manner, which aligns perfectly with the definition in the correct choice. A tirade typically addresses grievances, frustrations, or criticisms directed towards a person, group, or situation, making it distinct for its passionate tone.

In contrast, the first choice suggests a positive context of a "famous speech," which does not capture the essential tone of anger associated with a tirade. The third option, “a short remark,” is fundamentally different since a tirade is far from brief; it implies a substantial amount of speech. Lastly, the notion of an "official announcement" represents a formal declaration and lacks the emotional intensity and critical nature inherent in a tirade. Thus, the definition aligns closely with the characteristics of a long, angry, and critical speech.
