Answer Details
, "paid up," does not fit the sentence because it suggests that the experiment paid a debt or bill which is not what is intended in the sentence. "paid for," is also incorrect because it implies that the experiment was a purchase. "paid out," is also not correct because it suggests that money was distributed. The correct answer is "paid off," which means the experiment was successful or achieved the desired result after many attempts.
