Apparently, you didn't understand what the other tutors were telling you. The answer you wrote earlier today was going in circles:
The inventions of the late 1800s made it easier to do business because they helped commerce, industry, as well as the growth of the economy?

I sure hope that wasn't a question!!

Anyway, you should keep the first part of that sentence and after the word "because" give some actual examples. Name some inventions that helped business people and tell HOW they helped them conduct business more easily.
