There are strict, necessary conditions in this question. All we know is that :

Plowing the buried seeds exposes them to sunlight.

For germination, must have prolonged darkness followed by exposure to sunlight.

/D is a tough one. Redeposited seeds, though, are not a necessary condition. If seeds have PDFS, they should still germinate.

/B Will plants grow if not plowed or if not exposed to sunlight? We just don't know.

/C Again, will there be growth without sunlight? We don't know.

/E Surface seeds do not meet necessary PDFS, and will not germinate.

(A) Seeds that meet necessary germination conditions grow more than one that don't meet those conditions, specifically sunlight exposure. Yes.

Have the "Old Problem Sets" now been removed from the syllabus? Did I miss an update on this happening?
