Answer:
The utility that U2 represents is twice as higher than the utility that U1 represents.
Explanation:
An indifference curve is the locus of combination of two commodities bundles that yield the same level of satisfaction or utility to the consumer.
An indifference map is a graph that present two or more indifference curves that yield different level of utility to the consumer.
The farther away an indifferent curve from the origin, the higher the level of utility the consumer derives from the combinations of two goods it represents.
Therefore, if we have two indifference curves U1 and U2 representing the consumption of two normal goods. If U2 is twice as far from the origin as U1, then the utility that U2 represents is twice as higher than the utility that U1 represents.
