Answer:
Accidental errors.
Explanation:
As the exercise explains, a random/accidental error remains in after mistakes and have been eliminated. They are caused by factors beyond the control of the observer. They are present in all surveying observations. This type of error usually result from human mistakes or accidental errors. The latter type are errors caused by changing experimental conditions, out of the control of the individual doing the study or experiment. It's hard to quantify how "disastrous" they can be given that most of the times it depends on the context of the study.
