Explanation:

Step1: Understand percent error formula

Percent error = $\frac{\vert error\vert}{actual\ value}\times100\%$. The value of percent error depends on both the error and the actual value.

Step2: Analyze each option

• Option 1: Brand of calculator has no relation to percent error formula.
• Option 2: Since percent error formula has actual value in denominator, 3.5 ft error's percent error nature (large or small) depends on actual measurement value.
• Option 3: Sign (positive or negative) of error (as it's in absolute value in formula) doesn't determine if it's large or small percent error.

Answer:

depending on the size of the actual measurement value.
