A resistor with a gold band in the fourth position has a tolerance of ___.

Explanation:
In a four-band resistor, the fourth band indicates tolerance—the amount the actual resistance can vary from its nominal value. Gold on that band means ±5% tolerance. So the resistor’s actual resistance can be within 5% above or below its stated value. The other tolerance colors correspond to different percentages, but gold specifically corresponds to ±5%.
