Question 8

The plumber most likely used a flexible tube.

A flexible tube is generally utilized in situations where maneuverability is required, such as in opening up a curved pipe. It can easily bend and adapt to the shape of the pipe, making it the most suitable choice for this task.

A) Solid

A solid tube would not be appropriate for this situation as it lacks the ability to navigate around curves. Its inflexible nature would prevent it from effectively opening up a curved pipe, making it an unsuitable option.

B) Rigid

While a rigid tube could potentially be used in some plumbing applications, it would struggle with flexibility in navigating curves. The inability to bend makes it less efficient for opening up a curved pipe compared to a flexible tube.

C) Flexible

A flexible tube is the ideal choice for this task as it can easily conform to the curves of the pipe. Its design allows for better maneuverability, making it effective in opening up areas that are not straight.

D) Perforated

A perforated tube is designed to allow fluid to pass through the holes in its structure, which is not relevant to the task of opening up a curved pipe. Its primary function does not align with the needs of the plumber in this scenario.

Conclusion

The flexible tube is definitively the correct answer, as it provides the necessary adaptability to navigate curves effectively. All other options fail to meet the requirements for this plumbing task due to their lack of flexibility or relevance to the task at hand.
