Final answer:
Push factors are conditions that drive people away from their current location, like political unrest, famine, or natural disasters, and discourage them from choosing certain travel options.
Step-by-step explanation:
In the context of travel and migration, push factors refer to conditions that drive people away from their current location or discourage them from choosing a particular travel option. These conditions could be a wide range of negative aspects such as political unrest, poverty, war, land shortages, famine, natural disasters, high crime rates, lack of resources, or discrimination. These factors essentially push individuals to seek better opportunities elsewhere, leading them to migrate from their homeland to new regions.
Therefore, the correct answer to the student's question would be: 3) Factors that discourage people from choosing a particular travel option. Contrary to push factors, pull factors are those that attract people to a particular destination, such as better economic opportunities, peace and stability, or higher quality of life.
