[AI-generated answer — Bot GPT 3.5]

It is advisable to start with mark more than one when using a meter rule to measure the length of an object to improve the accuracy and precision of the measurement. By making multiple marks, it helps to minimize the errors that can occur during measurement due to factors such as parallax, human variability in reading measurements, and imperfections in the meter rule itself. Taking multiple measurements and averaging them can help to reduce random errors and provide a more reliable and accurate measurement of the length of an object.
