Answer:
The correct answer is: People can act unpredictably when they are betrayed by someone they love.
Explanation:
This text describes the Maloney's family where Mary lives an empty life because her husband is not present in their marriage. She does all the necessary jobs and acts as a real housewife, as her husband doesn't participate in their marriage life. Mary feels really bad about it and she cannot stand her husband's behavior, she feels betrayed by her husband, as we can see from the following paragraph:
At that point, Mary Maloney simply walked up behind him and without any pause, she swung the big frozen leg of lamb high in the air and brought it down as hard as she could on the back of his head.
She acted unpredictably and hit her husband with the big frozen leg of a lamb because she could not stand the fact that she is the only one who gives her best at this marriage and that she has to do all jobs alone. She takes these facts as a betrayal and decides to hurt her husband physically as he hurt her emotionally.
