Pluto, the Kuiper belt, the Oort cloud and comets, sentence 2

Much further out, scientists think a vast shell of icy bodies, the Oort cloud, surrounds the whole Solar System, perhaps a quarter of the way to the nearest star.

Who acts: scientists, vast shell · What happens: think, surround · To what, where: whole Solar System · Speech: someone speaks here

This is a sentence of the lesson «Pluto, the Kuiper belt, the Oort cloud and comets» of the space 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 (scientists, vast shell), 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.
