I have ascertained that or this one
I can confirm that im thinking this
I will instruct you that
I hope to learn that

Answer 1

The correct answer should be I can confirm that im thinking this

That is because there is no hoping to find out or finding out in Aver. Aver is used when you know something and you declare it.

Answer 2

The meaning of the phrase is: "I can confirm that i'm thinkin this", as the word aver refers to a positive declaration, used to firmly assert a stance .

It is a strong confirmation or assertion of a fact or thought, said in a formal context. It was used in the Late Middle English (1450-1650). Today this expression has lost use in modern English .
