Reference Answer
### (a) Fault Tree Analysis (FTA)
**1. Definition and Purpose**
Fault Tree Analysis (FTA) is a top-down, deductive failure analysis technique used in safety and reliability engineering. It starts with a predefined undesirable state, known as the "Top Event" (e.g., a system failure), and systematically traces back in time to identify all possible contributing causes, including component failures, human errors, and environmental factors. The analysis uses Boolean logic to model the relationships between these causes.
