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'.

Example Input: Sentence 1: The first few Mersenne primes are 3, 7, 31, 127 and 8191. These numbers took a total of several weeks to verify, using different software and hardware. Each number was independently checked by several members of GIMPS' verification team, using 16-core systems of different configurations. The two primes were announced by GIMPS on September 16. Before these two discoveries, the two previously largest known prime numbers were discovered by UCMO professors Curtis Cooper and Steven Boone in Missouri, United States, and their record lasted almost three years. Historically, prime numbers discovered by GIMPS are larger than the one previously found. The only other exception was when the 29th Mersenne prime was discovered after the 30th and 31st were found. Founded by M.I.T. graduate George Woltman in 1996, GIMPS has found 12 Mersenne primes, or about one per year on average. Sentence 2: Steve Boone is a member of GIMPS.
Example Output: 0

Example Input: Sentence 1: 20 million years ago there were apes, and by 5 million years ago our closest ancestors and cousins, early ape-humans, had split from the other apes. Sentence 2: Humans existed 10,000 years ago.
Example Output: 0

Example Input: Sentence 1: A month after Gov. David A. Paterson dropped his proposal for a soda tax, New York City's health commissioner has written an article advocating "hefty" taxes on sodas and sports drinks containing sugar. Such a tax, the article said, could be the biggest boon to public health since tobacco taxes. The commissioner, Dr. Thomas R. Frieden, and Kelly D. Brownell of Yale University, his co-author, argue in the New England Journal of Medicine that a tax of a penny per ounce could reduce consumption by more than 10 percent and raise $1.2 billion a year in New York State alone. Sentence 2: Michael Bloomberg is the mayor of New York.
