Definition: 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'.
Input: Sentence 1: Of all the national park lands in the United States, none is closer to a major urban area or more beset with problems than the Everglades, a shallow, 50-mile-wide river of grass that flows south from Lake Okeechobee to Florida Bay. For more than a generation, this fragile natural wonder has been held hostage by a web of special interests -- farmers, sportsmen and about 6 million South Florida residents in need of drinking water and flood control -- that is as complex as the ecosystem itself. Sentence 2: The Everglades is 50-mile wide.
