Question

the scientific
starts out when you ask a question.
the hypothesis is the second step
method
placebo
conclusion

Explanation:

The sentence is about the scientific process. The "scientific method" is a well - known concept where the process starts with asking a question and the hypothesis is a subsequent step. "Placebo" is related to medical experiments (like in drug trials) and "conclusion" is the end of a process, not the start. So the correct word to fill in is "method".

Answer:

method
