Answer 1

1) Were enormously rich and successful.
2) Had philanthropic/humanitarian tendencies
3) Advanced 1800's America through the techniques and goods they invented/provided

Answer 2

Both held monopolies.

Step-by-step explanation:

Andrew Carnegie was a major industrialist in the steel sector. John Rockefeller also was a major industrialist but he was in the oil company.

Both of them were one of the wealthiest men in the 20th century. This was possible because during that time the US government held the laissez-faire policy, which meant that the government did not protect consumers from monopoly.

Both Carnegie and Rockefeller held monopolies in their fields, this meant that these companies were so big that they had could reduce costs and close smaller companies by crushing them into their profit.
