Answer:
violence
shortages
jobs
Step-by-step explanation:
Why the answer is not oil: Venezuela is known as an oil producer, and exports large amounts of oils (in fact, it is one of their main exports). Venezuelans do not generally have a shortage of oil, and so they do not need to seek asylum in the US for oil. Also, the US would not grant them asylum in the US because of a shortage of oil anyways.
