What did you learn about american dependence on foreign oil?

The correct answer to this open question is the following.

The United States was too dependent on oil produced in other countries.

One good example of this US dependency of oil produced in foreign countries was the oil crisis in 1973 and 1979. The United States faced gas shortages in those years because the OPEC disrupted oil supplies. OPEC stands for Organization of Petroleum Exporting Countries. In those years, American citizens had to withstand long lines in gas stations to get some gasoline.

in the 1800s, chinese workers migrated to the united states, first to work in the gold mines, but also to take agricultural jobs, and factory work, especially in the garment industry. chinese immigrants were particularly instrumental in building railroads in the american west, and as chinese laborers grew successful in the united states, a number of them became entrepreneurs in their own right. as the numbers of chinese laborers increased, so did the strength of anti-chinese sentiment among other workers in the american economy. this finally resulted in legislation that aimed to limit future immigration of chinese workers to the united states, and threatened to sour diplomatic relations between the united states and china.
