According to Professor Amartya Sen, only democracies (but not dictatorships) have in-built protective systems that prevent famines. That is why India, even in its greatest crises, has had no famines since Independence but China has suffered acutely. Which of the following, if true, most seriously weakens Professor Sen's argument?
1) China has a much larger population than India's.
2) The Bengal Famine of pre-Independence India created an unique bias in Professor Sen's mind.
3) Nepal, which is a monarchy, has never suffered from famines.
4) In a democracy, the distribution of food gets affected due to excessive bureaucratic interference.
5) A famine can occur only after a certain length of time.
