Alguie puede ver en este parrafo algun sustantivo que no este marcado con comillas? Gracias!

The third and final period (C) saw the tragic collapse (C) of the earlier way of life. The causes (C) of the island’s change and decline were complex, but mainly due to one thing (C) – the destruction (U)of a large number of trees (C). Starting at least 1,200 years ago, this meant that there were almost no large trees left by the time the Europeans (C) came in the 18th century.

Answer 1

way, life, island, change*, decline*, number, years, trees, time, century

• change y decline también pueden ser verbos, pero aquí funcionan como sustantivos.
