This is a sentence of the lesson «The polar zone: arctic foxes, snowy owls, lemmings and reindeer» of the biology course of Mova's primary school. The page gives its syntax tree — a dependency tree in the style of Universal Dependencies — and its pragmatics clause by clause: who acts (Arctic, Antarctica, seals), what happens, when and where, as Mova's frames read it from the tree.

The frames are read from the tree by Mova's frames reader (prag) when this page is built, the lesson read in order, so a pronoun may be resolved from an earlier sentence.
