Final answer:
Scout and Jem learn that their father is an 3) expert shooter when he skillfully handles a rabid dog incident, which is significant in 'To Kill a Mockingbird'. Being an expert shooter in literature often represents a character's hidden skills and the ability to remain collected under pressure.
Step-by-step explanation:
Scout and Jem discover that their father, Atticus Finch, is an expert shot with a rifle in the classic novel 'To Kill a Mockingbird' by Harper Lee. This is revealed when Atticus is called upon to deal with a rabid dog in their neighborhood, a task he performs with skillful precision, to the amazement of his children who see him in a new light. Throughout literature, being an expert marksman often symbolizes control, precision, and the ability to handle unexpected challenges, characteristics that Atticus exemplifies.
The theme of unexpected skills in characters crops up frequently, as seen in anecdotes where sharpshooting figures, such as those with gray eyes, are expected to have exceptional aim due to keen eyesight, yet sometimes they miss, emphasizing that there's always an exception to the rule. The instance with Patrolman Lazarus as a crack shot highlights the allure of marksmanship and the expectations that come with a reputation for precision.
Considering the context in which we see these portrayals of skill with a firearm, whether in the hands of a composed figure like Atticus or a Guard with seemingly innate talent, it boils down to the moment's pressure and the person's ability to remain composed. In the case of 'To Kill a Mockingbird,' Scout and Jem's view of their father is forever changed as they understand the depth of his quiet competence, resonating with readers about the hidden talents that individuals may possess.
Therefore, the correct option to complete the statement "Scout and Jem find out that their father is a(n) _____ shot with a rifle when he had to kill a mad dog" is option 3) Expert, which I will mention in my final answer.
