Answer:
She wasn't the least bit surprised to find out that her husband had an affair. (SURPRISE) It wasn't surprising to find out that her husband had an affair.
Step-by-step explanation:
The word "surprising" is an adjective which means, 'causing surprise', or unexpected. When used in the sentence above, we see that it maintains the same meaning with the first sentence. In the first sentence, the woman was not surprised when she discovered that her husband had an affair.
In the second sentence, it was not a cause for surprise, when she found out that her husband had an affair. Therefore, the two sentences retain the same meaning.
