Sometimes I think Grand Central is growing like a tree, pushing out new corridors and staircases like roots. There’s probably a long tunnel that nobody knows about feeling its way under the city right now, on its way to Times Square, and maybe another to Central Park. And maybe. because for so many people through the years Grand Central has been an exit, a way of escape maybe that’s how the tunnel I got into. But I never told my psychiatrist friend about that idea.

Why did he think that Grand Central was growing like a tree?

(a) because it had a lot of trees in it
(b) because it had a lot of corridors and staircases
(c) because it had a lot of trees aroundit
(d) because it had a continuously been under construction
