Explanation:

In scientific research, the first step after receiving an unknown substance is to develop a research - able question. This helps in formulating a clear direction for the investigation. Measuring the melting point (without a prior question about its identity) might be premature. Writing a presentation or proposing a data - analysis method also comes after having a well - defined research question.

Answer:

Develop a specific, researchable question about how to identify it.
