Task: 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'.

Positive examples:
input: Sentence 1: No Weapons of Mass Destruction Found in Iraq Yet. Sentence 2:Weapons of Mass Destruction Found in Iraq.
output: 0
explanation: 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.; input: Sentence 1: A place of sorrow, after Pope John Paul II died, became a place of celebration, as Roman Catholic faithful gathered in downtown Chicago to mark the installation of new Pope Benedict XVI. Sentence 2: Pope Benedict XVI is the new leader of the Roman Catholic Church.
output: 1
explanation: In the given first sentence we can clearly understand that Pope John Paul II has died and Pope Benedict XVI was elected as the next Pope which is what the second statement also says. Hence, our output will be 1 for entailment; input: Sentence 1: Herceptin was already approved to treat the sickest breast cancer patients, and the company said, Monday, it will discuss with federal regulators the possibility of prescribing the drug for more breast cancer patients. Sentence 2: Herceptin can be used to treat breast cancer.
output: 1
explanation: In this example, our first sentence says that the Herceptin was already an approved drug for treating breast cancer patients and the same is said by Sentence 2 as well. So our output will be 1 for entailment.; input: Sentence 1: Nearly 4 million children who have at least one parent who entered the U.S. illegally were born in the United States and are U.S. citizens as a result, according to the study conducted by the Pew Hispanic Center. That's about three quarters of the estimated 5.5 million children of illegal immigrants inside the United States, according to the study. About 1.8 million children of undocumented immigrants live in poverty, the study found. Sentence 2: Three quarters of U.S. illegal immigrants have children.
output: 0
explanation: In the first sentence it is written that from the total of 5.5 million children of illegal immigrants nearly three quaters were born here in U.S. There is no mention of the count of how many illegal immigrants have children in the first statement. Hence, the output will be 0 for non entailment

Negative examples:
input: Sentence 1: Valero Energy Corp., on Monday, said it found "extensive" additional damage at its 250,000-barrel-per-day Port Arthur refinery. Sentence 2: Valero Energy Corp. produces 250,000 barrels per day.
output: 0
explanation: The first statement mentions that there was damage found in the 250,000 barrel-per-day Port Aurthur refinery. Which means that they produce 250,000 barrels a day. Hence the output should have been 1 for entailment; input: Sentence 1: A man is due in court later charged with the murder 26 years ago of a teenager whose case was the first to be featured on BBC One's Crimewatch. Colette Aram, 16, was walking to her boyfriend's house in Keyworth, Nottinghamshire, on 30 October 1983 when she disappeared. Her body was later found in a field close to her home. Paul Stewart Hutchinson, 50, has been charged with murder and is due before Nottingham magistrates later. Sentence 2: Paul Stewart Hutchinson is accused of having stabbed a girl.
output: 1
explanation: In this example our first sentence only mentions that Paul Stewart Hutchinson has murdered the girl. There is no information in the statement about the how she was killed and so since the second statement mentions she was stabbed our statement does not entail. So output should have been 0.
