33.Disaster is an event arising out of:  A. Result of hazard event  B. Causes of hazard event  C. Causes of disaster event  D. All of these

To answer the question about what disaster is an event arising out of, let's analyze each option carefully:

1. Result of hazard event: A disaster often results from hazardous events, such as natural disasters (earthquakes, floods, etc.) or human-made hazards (industrial accidents). This suggests that disasters are indeed outcomes of hazard events.

2. Causes of hazard event: This option implies an earlier stage, where the cause of a hazard is related to the disaster itself. However, a disaster is not caused by the causes of a hazard, but rather by the hazard event itself.

3. Causes of disaster event: This option could refer to the various factors that lead to a disaster. However, like the second option, it doesn’t directly address what constitutes the event of a disaster.

4. All of these: This option suggests that disasters can arise from a combination of the above factors.

Conclusion:

Based on the analysis, the best choice is A. Result of hazard event. Disasters primarily arise from hazard events rather than their causes. However, it's worth noting that option D highlights a broader perspective of understanding the entire ecosystem of disasters, including their causes and effects. Nonetheless, in technical terms, disasters are outcomes of hazards.

Final Answer

A. Result of hazard event
