Answer:
He wrung as much water out of the towel as he could before hanging it up.
When she heard the news, she wrung her hands in frustration.
Step-by-step explanation:
As given in the question, the definitions of the two words "rung" and "wrung" are different. While "rung" is a noun, the word "wrung" is a verb, which clearly shows their difference easily.
Now, the correct use of the verb "wrung" is found in sentences 1 and 2. In sentence 1, the transitive verb is used to refer to the act of extracting, squeezing out the excess water from the towel. Sentence 2 refers to the act of inflicting pain in oneself, like "she wrung her hands in frustration".
Thus, the correct answers are
He wrung as much water out of the towel as he could before hanging it up.
When she heard the news, she wrung her hands in frustration.
