he used
to obtain the truth.
\so if i drop these cannonballs at the same time\
options: placebos, conclusions, experiments (visual elements: pink circles with option text)

Explanation:

Galileo is known for using experiments (like dropping cannonballs) to test scientific ideas and obtain proof. "Placebos" are related to medical trials with fake treatments, and "conclusions" are the results, not the method to obtain truth. So the correct word is "experiments".

Answer:

experiments
