Answer 1

「\(2 \%\」

Answer 2

The question seems ambiguous without context or related conditions, as the amount of force that needs to be applied to push a load can greatly depend on various parameters such as mass of the object, friction on surface, slope of the surface and others. However, it's a common practice in health and safety, especially manual handling, to only use a small percentage of one's personal force to avoid injury. On this basis, I'll assume this refers to occupational health and safety guidelines for manual handling in many countries, where individuals are advised not to apply more than about 5% of their body weight in pushing or pulling. From the provided options, \( 4 \% \) and \(2 \% \) are less than 5% and \(6 \% \) and \( 0.5 \% \) are more than 5%. Therefore, choosing the greater option from less than 5% would be more rational because the lesser force from the person can affect the efficiency of the work. On the other hand, a bigger force can have an effect that largely increases the risk of developing a health and safety issue. Therefore, it would be better to stay on lower side because "prevention is better than cure".
