How is 'practicable' defined in this context?

The term 'practicable' in this context emphasizes the idea that something is capable of being implemented or carried out, but it takes into account specific circumstances and the resources available. This definition acknowledges the potential limitations that might impact the feasibility of achieving the task. While 'capable regardless of circumstances or resources available' suggests a strong level of capability, it inherently recognizes that some tasks may only be feasible or practical when certain conditions or resources are present.

In contrast, the other choices imply different levels of feasibility that overlook this nuanced understanding. For instance, saying something is 'able to be achieved, regardless of the situation' would suggest that there are no restrictions or considerations for practicality, which is unrealistic. Meanwhile, defining it as 'able to be obtained during normal circumstances' might not fully encapsulate situations where unique circumstances can affect achievability. Lastly, 'dependent on external resources for success' doesn't fully capture the breadth of what practicability entails, as it is not solely reliant on external factors but also on the specific conditions and context in which tasks are attempted.

Therefore, the chosen answer accurately captures the essence of what 'practicable' means in practical application, while also recognizing that capability is often intertwined with specific circumstances and available resources.
