question: finite:infinite
choices.label: A B C D
choices.text: odd:even land:ocean positive number:negative number distant relatives:close neighbors
explanation: "finite" and "infinite" are completely complementary. "odd" refers to an integer that is not divisible by 2, "even" refers to an integer that is divisible by 2, and "odd" and "even" are completely complementary. "land" and "ocean" are one category, and the components of the earth are not only "land" and "ocean" but also the sky. "positive number" and "negative number" are one category, and there are zeros in the number in addition to "positive number" and "negative number". "distant relatives" and "near neighbors" are one category. in addition to "distant relatives" and "near neighbors", there are other people around.
