This is a sentence of the lesson «What day of the week will it be?» of the world 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 (Phones, mathematician), what happens, when and where, as Mova's frames read it from the tree.
