"Choosing appropriate architectures" - singular or plural agreement?
Choosing appropriate architectures {are} crucial
or
Choosing appropriate architectures {is} crucial
To my knowledge [choosing something] is a single action, it should be followed by [is]. Please correct me if it is wrong and will be great if you come up with a little explanation...!
Thanks in Advance.
