I found the following sentence (a) in a book. Is this grammatically correct? I feel “possible” is used wrongly.
(a) The best-before date can best be defined as the date showing the period fully possible to preserve the quality of the products so labeled.
How about (b), which I rewrote myself?
(b) ... the date showing the period during which it is fully possible to preserve the quality of the products so labeled.
Both of those versions have errors. I suggest this. (c) The best-before date can best be defined as the date after which the quality of the products so labelled can no longer be completely preserved.
