Answer:
one fourteenth if the original section
Explanation:
If Anna plants peas in four sevenths of her garden and herbs in the other two sevenths then she has used up six sevenths of the space that she originally started out with. She now only has one sevenths of her garden that she can now use. If she divides the one seventh into two pieces we assume that she has done so equally. This will result in having two even plots of one fourteenth. The answer is one fourteenth.
