question: land:rent
choices.label: A B C D
choices.text: wages:labor factory:worker capital:profit education experience:knowledge
explanation: "rent" is obtained by renting out "land". "wage" is obtained through "labor", but the word order is inconsistent with the query. "workers" works in a "factory". "profit" can be obtained by contributing "capital". "education experience" refers to the learning experience of people receiving scientific and cultural "knowledge" training in educational institutions, rather than obtaining "knowledge" through "education experience".
