Which answer provides the best definition of a subsistence crop?

Subsistence crops are plants which are grown by farmers for themselves and their family, leaving little or nothing to be marketed for money. (ex. rice, corn, and milk.)

Subsistence farming is a farming system in which farmers focus on growing enough food to feed themselves and their family.

the dust bowl, otherwise known as the dirty thirties, was a huge dust storm that killed multiple (and i mean  multiple) farmer's crops, leaving them homeless, and foodless, and jobless. in california, there were 5.7 million residents, and the population shrank as mexicans were repatriated. however, when the dustbowl happened, a lot of people began to move to california. by 1940, 250,000 people had arrived. therefore, your answer would be  the population increased, massively.  i hope this !
