Could I see the sentences, please?
If we imagine ourselves in the scene in which the witness speaks with a firm and confident voice saying "that is the man I saw", the most probable thing is that it convinces us because she is very sure of herself, the witness does not doubt it for a moment, she/he is stating it.
The word <u>averred</u> can be replaced by <u>stated</u> since they have the same meaning. Other synonims can be claim, declare or affirm.
Answer:
With
Explanation:
Ws or whs are the words used to ask ws or whs questions.
With is the word which is not used mostly to ask questions.
Why are you going?
When will you go?
Who is going?
Where are you?
So with is not one of the w's.
