Answer:

A decrease in length, or the use of a material with lower resistivity, or an increase in the cross-sectional area of the wire

Step-by-step explanation:

The resistance of a wire is given by

$R=(\rho L)/(A)$

where

$\rho$ is the resistivity of the material of the wire

L is the length of the wire

A is the cross-sectional area

We see that:

R is directly proportional to
$\rho$ and L - therefore if we decrease one of these two, the resistance of the wire will decrease too

R is inversely proportional to A - therefore if the increase the cross-sectional area, the resistance of the wire will decrease
