Which of the following are not abilities required to handle the physical demands of construction work?

The correct answer is that seeing and differentiating between colors is not an ability specifically required to handle the physical demands of construction work. While color vision can be important in certain tasks — such as identifying electrical wires or reading color-coded blueprints — it does not directly relate to the physical capabilities needed in the construction field, such as strength, endurance, or flexibility.

The other options mention various physical abilities that are directly relevant to the demands of construction work. For instance, yoga-level flexibility is a useful asset for performing tasks that may require bending or stretching in confined spaces. Endurance, indicated by the ability to run or walk long distances without a break, is also essential for the physical labor often required on job sites. Hence, these abilities directly contribute to a worker's capability to perform tasks safely and effectively in a construction environment.
