question: snow:frost
choices.label: A B C D
choices.text: water lily:lotus national flower:peony raindrop:dewdrop white crane:red-crowned crane
explanation: "snow" and "frost" are both weather phenomena, and both are essentially water. except for "snow" and "frost", fog is also a weather phenomenon and is essentially water. "water lilies" and "lotus" are the same thing. china's "national flower" has not yet been determined, and there are several versions. among them, plum blossom and "peony" have become strong competitors, which are inconsistent with the logical relationship of the query. "raindrops" and "dewdrops" are essentially water. except for "raindrops" and "dewdrops," the essence of rain is also water. "white crane" and "crane" are both cranes. except for "white crane" and "crane", red-crowned cranes are also cranes, but they are not water in nature, which is inconsistent with the logical relationship of the query.
