Answer:
the push factor of famine and the pull factor of food availability.
Explanation:
The movement of poor Irish immigrants to the United States in the 1800s is an illustration of the push and pull factor of famine and food availability.
The poor Irish emigrated to the United States in the 1800s because they had little or no food in their country and they were attracted to the availability of food in America, hence their migration.
