choices.text: forest:poultry cattle and sheep:livestock environment:field early spring:severe winter
explanation: "flowers" are a type of "plant". "poultry" refers to artificially raised birds and animals, and there is no obvious logical relationship between "forest" and "poultry". "cattle and sheep" is a kind of "livestock". "field" is part of "environment". "early spring" and "severe winter" are the names of the seasons.
