Answer

The original statement is false. A 4-pound object weighs less than a 2000-gram object.

Work Step by Step

$1~kg = 1000~g$ $1~lb \approx 0.45~kg$ We can convert 2000 g to units of pounds. $2000~g = \frac{2000~g}{1}\times \frac{1~kg}{1000~g}\times \frac{1~lb}{0.45~kg}$ $2000~g = 4.44~lb$ We can see that the original statement is false. A 4-pound object weighs less than a 2000-gram object.
