Final answer:

The resistance of a conductor can be decreased by either decreasing the length or increasing the cross-sectional area.

Step-by-step explanation:

The resistance of a conductor can be decreased by either decreasing the length or increasing the cross-sectional area.

Decreasing the length: When the length of a conductor is decreased, the resistance decreases because there is less material for the current to flow through.

Increasing the cross-sectional area: When the cross-sectional area of a conductor is increased, the resistance decreases because there is more space for the current to flow through.
