# Vents and trenches: tubeworms, iron snails, the Challenger Deep and life without sunlight, sentence 9

<!-- .ven lang=en -->
The Challenger Deep in the Mariana Trench is the deepest point of the ocean, nearly eleven kilometres down, and two men first reached it in 1960 in the submersible (a small deep-diving craft) Trieste.

<!-- .vintro -->
**Who acts:** Challenger Deep, two men · **What happens:** be, reach · **To what, where:** deepest point, Deep, 1960

<!-- .vabout -->
This is a sentence of the lesson «Vents and trenches: tubeworms, iron snails, the Challenger Deep and life without sunlight» 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 (Challenger Deep, two men), what happens, when and where, as Mova's frames read it from the tree.
