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'.

Ex Input:
Sentence 1: A run by Mr. Feinblatt would complicate what is already a three-person race because he most likely would have the support of the powerful mayor, who is running for a third term. Such a move could also irritate the outgoing district attorney, Robert M. Morgenthau, because it could hurt the chances of his preferred candidate, Cyrus R. Vance Jr. The relationship between Mr. Morgenthau and Mr. Bloomberg has been strained, in part because of the district attorney's investigation into the fire at the former Deutsche Bank building, which found that lapses by the city had contributed to the deaths of two firefighters. Sentence 2: Feinblatt works for Bloomberg.

Ex Input:
Sentence 1: On August 21, the Polish weekly Przekrój published an advertisement for Dan-Mark exercise books, bearing the logo of 4fun.tv, a Polish music/interactive  TV station. Part of the advertisement contained a definition of the word "exercise book". The wording looked familiar, and Wikinews consulted Wikipedia,  the collaborative online encyclopedia. Upon seeing the Wikipedia definition, it appeared that the entry quoted in the promotional material was identical to the initial two paragraphs of the relevant Wikipedia entry. Sentence 2: Readers of online encyclopedias can edit the contents.
