Every design chunk in Intention Space can be associated with a set of phrase pairs, represented as JSON objects, which are generally referred to as QnA Statement Pair in Intention Space, where the pair can include placeholders and regular expressions, e.g. {'question':, "Simon Is Served, 'answer':'Fish Fry'}   is a question-answer pair,  {'question':,"Simon Is Served, 'answer':'_'}  is a question-answer pair with the place holder '_'. Similarly, {'question':'* is Served', 'answer':['priya', 'john',' Richard]} is a question-answer pair with a regular expression '*'.
We can look at the execution of the design chunk to include either reading or writing the JSON statement pair set(QnAs) associated with the design chunk. In that sense, a Design Chunk can be looked upon as an operator that works on a field of QnAs.  A design chunk with no QnA  ,however, do also take part in performing computation steps of Intention Space as defined in the computation progression model , described below. In the model we shall refer to aJSON statement pair as simply as QnA. We shall see this set of QnAs provide us the domain on which the Intention Space operators operates.
