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: Today Wikipedia, the free encyclopedia that anyone with access to the Internet can edit, was the victim of an onslaught of practical jokes, as April Fool's Day kicked in various timezones around the world, at least those parts which follow the Gregorian calendar. It is believed that Wikipedia contributors were kept busy tidying up and removing prank articles and changes made by other Wikipedia contributors, and were expecting to be cleaning up the aftermath for days afterwards. Sentence 2: Readers of online encyclopedias can edit the contents.
