choices.label: A B C D
choices.text: propaganda:promotion request:approve abstract:concrete expense:income
explanation: "bidding" can be "won the bid" before "bidding", "bidding" and "bidding" exist in a time-dependent manner, and the subjects of the two are different. "propaganda" is a method of "promotion", and "propaganda" corresponds to "promotion", but there is no obvious chronological order between the two. "request" first, then "approval", "request" and "approval" exist in a time-dependent manner, and the subjects of the two are different. "abstract" and "concrete" have opposite meanings. you can have "income" first and then "expense", or you can have "expense" first and then "income", there is no obvious chronological order between the two.
