## Instruction

```
You are given a deep information synthesis question that requires gathering
data from multiple web sources and producing a structured JSON answer.

I am analyzing quarterly population dynamics in Australia from 2004 to 2024. For each quarter within this period, determine whether total population growth for that quarter was lower than the natural increase for the same quarter. Identify all quarters in which this condition is met and group them by year. Present the results in JSON format, where each key is a year and each value is a list of the quarters (e.g., "Q1", "Q2", "Q3", "Q4") in that year for which total population growth was lower than the natural increase. Only include years that contain at least one such quarter.

Research this question thoroughly by browsing the web. Find relevant data
from official sources (government databases, statistical offices,
international organizations). Synthesize the information into a single
JSON answer.

Write your final answer as a valid JSON dictionary to `/app/answer.json`.
The answer should be a JSON object matching the format specified in the
question above (typically string keys with numeric values).

Example answer format:
```json
{"Country A": 1.23, "Country B": 4.56}
```

**Important:**
- You should ONLY interact with the environment provided to you AND NEVER ASK FOR HUMAN HELP.
- Show your work and reasoning before writing the final answer.
- `/app/answer.json` should contain ONLY the valid JSON dictionary — no explanation, no markdown fencing.
