Final answer:
Objective evidence should be unbiased, collected through experiments or direct observations, and provide measurable results.
Step-by-step explanation:
Objective evidence should be unbiased and collected through experiments or direct observations. It should provide measurable results and be based on facts rather than opinions or biases. For example, in a scientific experiment, objective evidence would be the data collected through measurements or observations that can be replicated by others. Objective evidence should be used to support arguments or conclusions in a fair and impartial manner, regardless of personal beliefs or hypotheses.
