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.
