Consider the fragment of the text and the following statements:

“A gaggle of commuters assembles inside and outside the train” (l.02).

I. ‘gaggle’ means, informally, a disorderly or noisy group of people.

II. ‘commuters’ designates people who travel some distance to work on a regular basis.

III. ‘assembles’ indicates a crowd that gather together in one place for a common purpose.

Which ones are correct?
