Answer:
D. Â Machine schematics were memorized and replicated or A. Â They sold the designs to machinery.
Explanation:
D would be correct because people from Great Britain such as Samuel Slater would memorize machinery schematics, leave Britain, and enter other countries. Â Then, they would replicate the machinery. Â It could also be A.
I'm almost positive it is D. Â You needed help fast so I didn't have enough time to look at my history lessons but from what I remember, I'm pretty sure this is correct. Â So sorry if it's not.
