Given the task definition and input, reply with output. In this task, you're given two sentences. Indicate if the first sentence clearly entails the second sentence (i.e., one can conclude the 2nd sentence by reading the 1st one). Indicate your answer with '1' if the first sentence entails the second sentence, otherwise answer with '0'.

Sentence 1: China yesterday threw down a challenge to America's 50-year dominance of the global economy as it proposed replacing the dollar as the world's main reserve currency with a new global system under the control of the International Monetary Fund. In a muscle-flexing move that will be seen as an attempt to exploit the big shifts in economic power created by the recession sweeping the West, Beijing said that the dollar's role could eventually be taken over by the IMF's so-called Special Drawing Right (SDR), a quasi-currency that was created in 1969. Sentence 2: The Special Drawing Right is a quasi-currency.
