Task: Question Answering
Input (English): Passage: On 2 March 1882, Roderick Maclean, a disgruntled poet apparently offended by Victoria's refusal to accept one of his poems, shot at the Queen as her carriage left Windsor railway station. Two schoolboys from Eton College struck him with their umbrellas, until he was hustled away by a policeman. Victoria was outraged when he was found not guilty by reason of insanity, but was so pleased by the many expressions of loyalty after the attack that she said it was "worth being shot at—to see how much one is loved". Question: What provoked the attack on Queen Victoria as she left Windsor? 
Output (English): offended by Victoria's refusal to accept one of his poems
