The task involves interpreting the graph depicting the productivity of two production lines to determine the answer to two questions:
- Can the duration of the reported breakdown be established?
- Can the loss of production be quantified?
For question A, the graph typically shows time on one axis and productivity levels on the other. If there is a distinct drop or flatline in the production line's performance over a specific time period, the duration of the breakdown can be estimated directly from the time axis. Therefore, the answer for A is yes—the duration of the breakdown can be established if the graph provides a clear indication of when the productivity stopped and resumed.
For question B, quantifying the loss of production would require specific data points, such as the expected productivity versus the actual productivity over the timeframe in question. If the graph does not provide numerical values or the baseline production level, then it is difficult to numerically quantify the lost production directly from the graph.
Given these observations, the correct option is "Only A question can be answered" as the graph allows for determining the duration of a breakdown but not directly quantifying the production loss without additional numerical data.
