What type of troubleshooting tool asks a series of questions with yes or no answers?

The correct choice is a flow chart. A flow chart is a visual representation of a process that guides users through a series of steps or questions that can typically be answered with yes or no. This method is particularly useful in troubleshooting because it leads the user down different paths based on their responses, effectively narrowing down the potential causes of a problem. Each yes or no response directs the user to the next question or step, allowing for a systematic approach to diagnosing issues.

In contrast, a sequencing chart organizes tasks or events in a specific order but does not inherently use yes or no questions to guide decision-making. A Pareto chart visually represents data to identify the most significant factors in a problem but does not function as a troubleshooting tool in the way that allows for yes or no questioning. The half-split method is a technique used to systematically narrow down possibilities, but it isn't strictly about asking yes or no questions in a flow format.
