Solution & Step-by-step Explanation
The paragraph establishes a historical description of events in the past, using past-tense verbs consistently ("started", "recorded", "crept", "stopped", "died"). To maintain proper narrative consistency, the verb in blank 5 must be in the simple past active voice.
Triggered is the active simple past form, showing that the smoke directly brought on the medical incident.
Was triggered is passive, which breaks the grammar since "smoke" is the active subject doing the triggering.
Hence, 'triggered' is the correct fit.
