Please solve the programming task below using a self-contained code snippet in a markdown code block.

You own a Goal Parser that can interpret a string command. The command consists of an alphabet of "G", "()" and/or "(al)" in some order. The Goal Parser will interpret "G" as the string "G", "()" as the string "o", and "(al)" as the string "al". The interpreted strings are then concatenated in the original order.
Given the string command, return the Goal Parser's interpretation of command.
 
Please complete the following python code precisely:
```python
class Solution:
    def interpret(self, command: str) -> str:
```
