— Answer ranges and tolerances are now allowed for chartography tasks only
New: Chartography tasks may use answer ranges or tolerances. Check the task's category to confirm its type. If the category does not say chartography, this exception does not apply—even if the image looks like a chart.
For a chartography task, if a number is not printed on the chart and you estimate it from the gridlines, give your estimated answer plus the range you would accept. State the accepted range or tolerance clearly in the prompt. The model's wrong answer must fall outside that accepted range; an answer within the range is not a stump.
Example prompt:
In the stress-strain chart, what stress does the Alloy B curve reach at 0.6% strain? Round to the nearest 5 MPa; estimates within ±10 MPa are acceptable. Answer as <number> MPa (e.g., 245 MPa).
If your estimated answer is 245 MPa, the accepted range is 235–255 MPa. A model answer of 250 MPa is within the range and is not wrong; 270 MPa is outside it.
All non-chartography tasks retain the previous guidance: use one single, clear, verifiable final answer. Do not use ranges or tolerances that allow multiple accepted answer values. This announcement replaces the previous blanket restriction on answer ranges only for chartography tasks.
