prompt: What is the difficulty level of sentence: "Sicilian fertility, which had been everywhere famous,
  
  was given the lie when the crops died as they sprouted,
  
  now ruined by too much heat, and now by too heavy a rainfall;
  
  stars and winds harmed them, and the greedy birds devoured
  
  the seed as it was sown; the harvest of wheat was defeated
  
  by thorns and darnels and unappeasable grasses."?
