Who to figure out subject verb agreement

Excerpt from Appetite

Will Wordy

In a house the size of a postage stamp

lived a man as big as a barge.

His mouth could drink the entire river

You could say it was rather large

For dinner he would eat a trillion beans

And a silo full of grain,

Washed it down with a tanker of milk

As if he were a drain.

 Which does NOT describe how much the man can eat or drink?

A)lived a man as big as a barge.  

B)Washed it down with a tanker of milk  

C)His mouth could drink the entire river  

Eliminate

D)For dinner he would eat a trillion beans  

the answer is "began" because it is a action that can be done
