Given the task definition and input, reply with output. 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'.

Sentence 1: A large proportion of young children in Ukraine suffer from various health problems that have probably gone undiagnosed until now, but which are being detected in connection with the Chernobyl disaster. This could well point to a weak health care system and harsh living conditions. Sentence 2: Chernobyl disaster had repercussions outside ex-USSR.
