Glass and pottery, sentence 18

Optical fibres are thin strands of glass that carry light along bends, because the light keeps bouncing inside the fibre; most of the internet travels through such fibres, even under the oceans.

Who acts: Optical fibres, glass, light, most · What happens: be, carry, keep, bounce, travel · To what, where: thin strands, light, fibre, such fibres

This is a sentence of the lesson «Glass and pottery» of the chemistry course of Mova's primary school.

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.
