<span>Since
there are no choices available I would assume that this is the answer. With the
settlement of people from fertile areas, knowledge of agriculture spread by
constant migration. During the early days, people thrived in their community
when there is fertile soil available for all forms of agriculture. But once the
land had been used up, people start to migrate to different locations where
they can possibly get their new food sources, thus knowledge of agriculture
spread into different areas. </span>
The correct answer should be<span> b
There was as yet no man, nor any animal, nor bird, nor fish, nor
crawfish, nor any pit, nor ravine, nor green herb, nor any tree; nothing
was but the firmament.
You didn't provide whether there's more possible answers, but this one is correct definitely. It shows that there was nothing and ex nihilo means that, out of nothing, which is what fits B.</span>
