Answer:
The right option that fills the blank is:
- The bargaining between both people.
- The main idea of this dialogue is the bargaining between both people.
Step-by-step explanation:
Within the text two people (customer and seller) negotiate closets, first, the customer sees a green one but knowing the price asks for a cheaper one, the seller offers one of fifteen thousand pesos, the customer offers ten thousand pesos and finally, the seller gives the final price of twelve thousand pesos, this whole cycle of situations corresponds to a negotiation regarding the price of the second closet, since unlike the other options given they are not signing a contract, discussing the color of the closet or checking the lowest price of something.
