Answer 2

Body parts are not a reliable instruments for measurement. This is because different people might have body part of different sizes. This can lead to inconsistent measurement. Therefore, body parts should not be used as a measuring instrument.
         Eg.- A child measures length of a table 5 hand spans and an adult measures the length of the same table as 4 hand spans. This is inconsistency in the results.
