Final answer:
While the statement regarding the use of a control zone and slope conditions seems specific, determining its truth requires the context of particular safety standards or regulations, which are not provided. To provide a definitive answer, one would need to reference the specific guidelines relevant to the safety measures being discussed.
Step-by-step explanation:
The student asks whether a control zone is only used if work can fall from a surface that has a slope of no more than 4 degrees towards an unguarded edge, or that slopes inwardly away from the unguarded edge and is not less than 2 meters wide when measured from the unguarded edge. The question's scenario seems specific, suggesting a particular safety standard or regulation. In the absence of explicit context, such as construction or workplace safety guidelines to reference, the sentence lacks clarity, but the phrasing strongly hints at safety measures considered in certain types of work environments. Given that the statement appears to specify conditions under which a control zone is applicable, the best approach is to guide the student to the specific safety regulations or guidelines relevant to the context they are studying. As such, the answer to the statement being true or false could vary, depending upon the specific regulatory guidelines being addressed. However, without a clear reference, this cannot be answered with certainty and should be approached by looking into the appropriate safety regulations in the relevant field.
