I believe the answer is: Benjamin disraeli
The challenge that initiated by Benjamin Disraeli damaged the relationship between the British empires and their colonies.
Before this, British empire colonized other countries for a trade/business relationship. But with Disraeli's new way of thinking, more of them were advocated to make the colonized countries become a part of the British empire and heavily involved in their politics.
The answer could be A or B , but I am not sure .
The most logical combination would be to decrease the production of balls, and increase the production of nets, in order to achieve a market equilibrium that allows both products to be sold. For this it would be necessary to allocate more money to the production of nets, and to diminsh the cost referred to balls, until arriving at half of expense for each one.
Because of industrial revolution, women have the opportunities to: A. Work outside the home in factories
Prior to industrial revolution, almost all jobs that exist in society utilize physical strength, which basically made women became less productive compared to men. After the industrial revolution, machinery replaced these physical works. This opened up paths for women to work outside the home in factories.
