In Priestley's second experiment, the correct response is that **the candle was extinguished immediately**.
For the second question regarding what was proven by Priestley's experiments, the correct responses are:
- **The process of photosynthesis releases oxygen into the environment**
- **A flame requires oxygen to burn**
The first option about photosynthesis absorbing oxygen is not correct, and the statement regarding carbon dioxide's role in fire is more related to the support of combustion rather than being proven directly by Priestley’s experiments.
For the second question regarding what was proven by Priestley's experiments, the correct responses are:
- **The process of photosynthesis releases oxygen into the environment**
- **A flame requires oxygen to burn**
The first option about photosynthesis absorbing oxygen is not correct, and the statement regarding carbon dioxide's role in fire is more related to the support of combustion rather than being proven directly by Priestley’s experiments.
