The argument derived from the title is that the rapid rise of crude oil price is not caused by the change of world oil supply and demand, and the conclusion is that the rapid rise of crude oil price is the result of crazy speculation of international speculative capital in the oil futures market.

Item A says: "From 2000 to 2008, governments all over the world generally increased their strategic oil reserves", which will obviously lead to an increase in total oil demand and affect the relationship between supply and demand, but it will not have a great impact on world oil consumption demand, which will greatly weaken the argument and further weaken the inference.

Item B: "A small economic growth rate always leads to a large oil demand growth rate", which supports the fact that the average annual growth rate of the world economy is around 5% in the same period, and the world oil consumption demand has not advanced by leaps and bounds.

Item C: "The asymmetry between the rate of change of oil demand and the rate of change of oil price" directly weakens the argument. The implication is that even if the total demand remains unchanged, there are still many other factors that will affect the price. Weakened the argument relationship. Otherwise, other reasons will be weakened.

Item D, even if it appears, can not effectively weaken speculative capital to invest in oil, just like buying lottery tickets. Isn't the risk small? Many people are still investing.
