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'.

Let me give you an example: Sentence 1: No Weapons of Mass Destruction Found in Iraq Yet. Sentence 2:Weapons of Mass Destruction Found in Iraq.
The answer to this example can be: 0
Here is why: In our first statement we clearly say that Iraq does not have any weapon of mass destruction but the second sentence says that weapon of mass destruction is found in Iraq which is contradiction. Hence output will be 0 for non entailment.

OK. solve this:
Sentence 1: International observers are surprised at the attack, given the recent advances that the Sri Lanka army has made, driving the LTTE from their former territories. "It is very significant that the rebels have carried out such an audacious attack when the government say that they are all but finished," opined BBC's Sinhala Editor, Priyath Liyanage. "It confirms what many of us already knew the rebels may be experiencing reverses on the battle field but they are not simply just going to disappear." Sentence 2: LTTE stands for Liberation Tigers of Tamil Eelam.
