      Task B - Our answer
      The sentence has the following structure: 
      
         
          |  
             S 
           | 
           
             P- 
           | 
           
             A 
           | 
           
             -P 
           | 
           
             O 
           | 
           
             A 
           | 
           
             A 
           | 
           
             A 
           | 
         
         
          |  
             She  
           | 
           
             has | 
           | 
           
             really | 
           | 
           
             pushed | 
           | 
           
             the boat | 
           | 
           
             out, | 
           | 
           
             perhaps | 
           | 
           
             a little too far. 
           | 
         
       
      (Note the way in which the first adverb comes in the middle 
        of the Predicator VP.) 
        
      The wry humour is effected by the contrast between the first part of 
        the sentence (up to the comma) and the rest. The first part of the sentence 
        is grammatically complete, and the last two Adverbials are non-obligatory 
        add-ons which undermine the earlier material. [S, P and O are obligatory 
        in transitive structures and the clause up to the comma is also a clichéd, 
        idiomatic expression in English, but Adverbials are more optional.] The 
        earlier material in the sentence is quite forceful ('pushed'is a dynamic 
        transitive verb and the Adverbial 'really' intensifies the force of 'pushed'). 
        Then the optional clause material, tagged on at the end, rather like an 
        afterthought, undermines the first part of the sentence, suggesting in 
        'a little too far' that the dynamic clothes-buying was ill-judged. And 
        if we compare the Adverbials 'really' and 'perhaps' we can see that an 
        intensifying adverb in the first part is replaced by a hedging, downtoning 
        adverb in the second, bringing out further the contrast between the two 
        parts of the sentence.
