Teachers. Which one is correct in this sentence, that, which, where?
The bank is a place( )they lend you umbrella in fair weather and ask for it back when it begins to rain.
A bank is a place that lends you an umbrella in fair weather and asks for it back when it begins to rain.
A bank is a place which lends you an umbrella in fair weather and asks for it back when it begins to rain.
As you can see, to use those two alternatives, you must remove "they" and consequently the third person plural verb forms change. The verb is now related to "A bank/a place" which are singular and therefore the third person singular verb form is required.
In the UK, banks no longer even offer you an umbrella! They're more likely to tip a huge bucket of ice-cold water over you and then stand around and laugh while you freeze to death!
