Uncertainty and percentage error

Hi, does anyone know how to explain why the experiment error would be higher than the apparatus uncertainty?
Btw this is a question for Required practical 2: (Measuring an Enthalpy change) of the new AQA AS chemistry spec


Thanks in advance
Because the apparatus used has smaller incremental values and therefore less margin for error. The experiment itself would have a higher chance of error as there are multiple factors that could result in an abnormal value depending on your experiment.
