Have to give you an "A" for effort on 1,3 and 4.
Although, your answers do seem to imply that there was some 'purpose' other
than quarry for the Ditch.
However 2 may not get by our 'puddled clay' expert, Andy Norfolk, who
assures us that the angle of repose of puddled clay is never greater than 16
degrees. Whereas the angle of the sides of the barriers are steeper than 16
degrees, the clay could not have been 'puddled clay', but must have been
some other form of clay which was probably deliberately applied as noted by
Col. William Hawley. Col. Hawley often emphasises that clay, compo and `a
great deal of light coloured clay mixed with chalk apparently purposely put
there' was deliberately applied.
We still need to give you an 'A' since your answer to 4 could conceivably
apply to 2 as well.
Will try to get you on the next question.
