Note
The -ing form does two jobs: it builds the progressive (she was concentrating) and it names the activity as a noun (concentrating takes effort). The mental sense is intransitive and takes on: concentrating on the task. The gathering sense works both ways. A general can be concentrating his forces, or the forces themselves can be concentrating near a border. The final e of concentrate drops before -ing.
She sat in silence, concentrating on the final question.
Enemy troops were concentrating along the river all night.
