question: rain:wet
choices.label: A B C D
choices.text: the 18-years-olds and above:have the right to vote bloom:bear fruit the ground is not wet:it is not raining friction:heat generation
explanation: Once it rains, the ground will be wet. "the 18-years-olds and above" may have "the right to vote", and those who are deprived of political rights do not have "the right to vote". "blooming" may "bear fruits". if "the ground is not wet", then "it is not raining". "friction" may have "heat generation", but static "friction" does not generate heat.
