The following sentence is taken from line 10:

> この[辺]{あた}りは農作物ができないため、江戸時代にこうした家内産業が発展した。

"Because in this area crops weren't possible, in the edo area ???? wife
industry made growth/grew."

"wife industry" sounds pretty odd, I guess it is meant that the wife does work
at home? However, what does this have to do with crops???




The English term for 家内産業 is "cottage industry."

Does it make sense now?
