The structure of CPs

Look at the following examples:

a) The child wanted to know [CP when his father would be back].
b) The man announced [CP that he would hand in his notice].
c) [CP When will John leave England]?

1. For each CP, identify the element that is situated in the head position and indicate the abstract features on the the head C°. List the complement and specifier. Name the category of those heads, complements and specifiers that are overtly realised

• If the head is not overtly realised, or if specifiers are absent, insert "/". Use "t" for traces.
  
• To indicate the abstract head features, choose from the following list of abbreviations: (+tns/+agr); (-tns/-agr); (+WH); (-WH); (+poss).
  
• Use the following abbreviations to indicate the category: NP, DP, VP, AP, PP, AdvP, IP, CP for phrases. If heads or specifiers are not lexically realised, insert "/".

2. Draw a simplified tree diagram to represent the structure of each CP.
