In ancient times, alchemists believed that gold could be made from lead. modern scientists believe that it is impossible to transform lead into gold. what best accounts for these different opinions? experiments provide fresh evidence for new interpretations scientific theories change with changes in properties of matter scientists come up with different hypotheses without enough evidence scientists propose different hypotheses to include all the scientific possibilities

The answer is Experiments provide fresh evidence for new interpretations. It is important to point out that scientific method was invented to provide a tool to evaluate claims like the one above. Hypothesis are not strictly scientific and they need to be subject to the rigours of such things as objective observation, error analysis, statistical analysis, and repeatability before they can be claimed as scientific fact, and generally need to be able t correctly predict future outcomes. Hypothesis and theoretical science do not provide an actual answer but give a basis of evaluation.
