These are some sentences I found in some academic books I was reading:
A small white blob is reflected there, precisely where Beth’s camera-flash left behind proof of her presence as if the daughter were some insurance company adjustor routinely investigating a home break-in.
Few inquiries into particular words end with the great Dictionary’s account, but even fewer could start with any confidence if it were not there.
What puzzles me is why the verb is used in plural whereas its subject is in singular. Could you please explain that to me?
