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 west has preferred to focus on endangered animals, rather than endangered humans. African elephants are hunted down and stripped of tusks and hidden by poachers. Their numbers in Africa slumped from 1.2m to 600,000 in a decade until CITES - the Convention on International Trade in Endangered Species - banned the trade in ivory. Sentence 2: The African elephant population was decimated by poachers.
Example Output: 1
