Question

Steve was given a set of 5 metal cubes. He calculated the densities of each several times to determine the type of metal in each. The densities were really close to each other after each calculation, so he asked his friend Robert to do the same experiment and see if he gets the same results. Which sentence from the report refers to replication?

A. The densities were really close to each other after each calculation, so he asked his friend Robert to do the same experiment and see if he gets the same results.
B. Steven was given a set of 5 metal cubes.
C. He calculated the densities several times to determine the type of metal.

Answer 1

The answer is A because replication is someone else repeating something so it can’t be C because that’s repetition since he is repeating it and it can’t be B because it’s just saying what he was given and has nothing to do with replication.
