Need help figuring out which sentence is written in the passive voice.

A. Kwame's whole life had been directed by his father - a powerful, confident man who ran an advertising agency.

Sentence A is the one written in the passive voice. Kwame's whole life is the subject but is the recipient of the action expressed by the verb directed. Kwame's father is the one performing this action, and we can see this with the help of the prepositional phrase with the preposition by (by his father). In active voice, the given sentence would look like this:

usually, a falcon can kill an owl, and horses don't normally eat each other.
