premise: A woman in a blue and brown parka with matching hat is in a snow-covered forest on either crosscountry skis or snowshoes, which are obscured by the ruts in the trail she is following. hypothesis: People are playing at the hot beach.
contradiction: One is speaking of one particular woman in a snow-covered forest while the second sentence refers to many persons, people, at a hot beach. They are not the same number of people.
