- However, the real breakthrough came in 1959, when one morning in the Olduvai Gorge - a region separating the famous National Park from Tanzania's more famous Serengeti National Park - Mary discovered a 1.75 million-year-old hominid skull, later classified as Parantropus boisei.

The correct answer is - A famine in Ireland prompts US response.
With the Irish famine of the 19th century, and the response to it by the United States, we have a very nice example of domestic influence on foreign policy.
Namely, the Irish potato famine was so bad, that very large percentage of the Irish population actually died, and the rest of the population was on the verge of starvation. Because of this, lots of people wanted to move out of the country in order to at least be able to have food on the table. This prompted a response from the United States, and they made an exception in their strict foreign policy because of the Irish people, so opened their borders to them in order to help them, thus letting them settle in the country.
