An economic push factor is typically a condition that drives people away from a particular location due to unfavorable economic circumstances. In the list you provided, "hyperinflation" best describes an economic push factor. Hyperinflation results in a dramatic increase in prices and a decrease in the real value of money, which can lead to economic instability and motivate individuals to leave their home country in search of better opportunities elsewhere.
The other terms can relate to various contexts but are not primarily described as economic push factors:
- "Brain drain" refers to the emigration of highly skilled or educated individuals, which can be a consequence of push factors.
- "Land ownership" can relate to economic conditions but is not directly a push factor itself.
- "Remittances" are funds sent back home by migrants and are typically a result of migration rather than a push factor.
So, the correct answer is hyperinflation.
