In your screenshot, the first number is an automatic number and the repeated number is hardcoded (typed in and editable).
It isn't apparent from your screenshot whether the A. to E. answers are hardcoded or automatic numbers so this can be a problem if you wanted an method to remove the hardcoded numbers from only the questions. Assuming they are all automatic numbers and you ONLY want to remove the hardcoded numbers from the questions then you can run a macro to do that to selected paragraphs.
Code:
Sub NumberingDeleteHardcoded()
'Only acts on selected paragraphs
Dim iResp As Integer
iResp = MsgBox("This macro will remove all hardcoded paragraph numbers " _
& vbCr & "from the SELECTED paragraphs. Click OK to continue.", _
vbOKCancel, "Delete Hard Numbers")
If iResp = vbOK Then
WordBasic.ToolsBulletsNumbers Replace:=0, Type:=1, Remove:=1
End If
End Sub
