choices.text: photography:shopping:travelling bidding:winning bidding:construction wholesale:retail:sales export:domestic:commodity
explanation: "recruitment" include "oral test" and "written test". We can "photography" and "shopping" when "travelling" "bidding winning" and "construction" correspond to the order of time. "sales" includes "wholesale" and "retail". the objects of "export" and "domestic" are "commodities", which are inconsistent with the query.
