I suppose each column in an Excel file of this kind represents a different question, and each row contains a different person's answer.
ENA isn't used in this way anywhere else in the file, and it still looks to me like the indefinite article. It says "ENA 10% ..." - the use of the indefinite article suggests to me that they mean a 10% portion, as thomgeor80 suggests.
A couple of rows further down, it's the same phrase with ENA omitted - "10% ..." - but I think it means the same thing. |
