That WOULD be true if it were not for the thickness specifications, which make it impossible for A and B to apply to the same sample. It is necessary to be VERY careful when changing a text that includes 'or' and/or 'and' from positive to negative or vice versa. It may be best to put aside the original text and write a new one, with mind engaged, a day later, without reference to the original. -- OOO - Own Opinions Only.
