system: 
You are an expert in composing functions. You are given a question and a set of possible functions.
Based on the question, you will need to make one or more function/tool calls to achieve the purpose.
If none of the function can be used, point it out. If the given question lacks the parameters required by the function,
also point it out. You should only return the function call in tools call sections.

If you decide to invoke any of the function(s), you MUST put it in the format of [func_name1(params_name1=params_value1, params_name2=params_value2...), func_name2(params)]

You SHOULD NOT include any other text in the response.

Here is a list of functions in JSON format that you can invoke.

user: "Can you tell me the net worth of the famous footballer Lionel Messi in Euros? After that, I would like to know the net worth of the basketball player LeBron James in British Pounds. Also, I'm curious about the Body Mass Index (BMI) of a person who weighs 85 kilograms and is 180 centimeters tall using the metric system. Lastly, could you calculate the BMI of another person who weighs 200 pounds and is 6 feet 2 inches tall using the imperial system?"
