As any economist knows, healthy people pose less of an economic burden

As any economist knows, healthy people pose less of an economic burden to society than unhealthy people. Not surprisingly, then, every dollar our state government spends on prenatal care for undocumented immigrants will save taxpayers of this state three dollars.

Lets breakdown this argument a little, to get a better understanding.
1. un-healthy people stress the economy of a society more than healthy people do ---- We can consider it as a Fact
2. Every dollar that the govt. spends on prenatal care for undocumented immigrants will save taxpayers more money.
So okay, this means that if the govt. provides pre natal care then it will somehow improve the health of people and thus save the tax-payers more money as increasing healthy people will reduce the stress on the economy.
Cool, that's the idea that we can guess till now.


Which of the following, if true, would best explain why the statistics cited above are not surprising?


(A) The state’s taxpayers pay for prenatal care of all immigrants. - might be true but does not really tell that why will the taxpayers benefit from this.

(B) Pregnant women who do not receive prenatal care are more likely to experience health problems than other pregnant women. - Ok, so less prenatal care -> more unhealthy people, So it makes the point that it is not surprising that the taxpayers would want to pay for it so that more prenatal care -> healthy people -> better economy.

(C) State benefits for prenatal care serve to promote undocumented immigration. - Not Relevant, Anyhow, if it supports undocumented immigration, then it will be bad and the taxpayers would not want to pay.

(D) Babies whose mothers did not receive prenatal care are just as healthy as other babies. - Weakens the argument, if pre-natal care does not do anything then why should the taxpayers pay for it.

(E) Babies born in this state to undocumented immigrant parents are entitled to infant care benefits from the state - Tricky, so one may think that prenatal care should be given so that the babies are healthy and later they would involve less care via infant care benefits so the economy will be better, BUT this will be reading a lot into the layers. As it is not really stated that Infant care impacts the economy or that prenatal care and the health is somewhat related. Which in the first fact is mentioned. Hence this option is eliminated.
