Final answer:
The dad taught Jeannette how to swim by throwing her into the deep end of the pool. This method, although unconventional, can be effective in helping someone learn to swim. So, the correct answer is option c.
Step-by-step explanation:
The dad taught Jeannette how to swim by throwing her into the deep end of the pool. In the book, it is mentioned that Jeannette can swim a little and that she goes to the Crystal Baths. However, she admits that she can swim only when her dad holds her chin up, and as soon as he lets go, she sinks. This suggests that her dad decided to teach her to swim by confronting her fear and forcing her to swim on her own.
This method may seem unconventional and even dangerous, but it can actually be an effective way to teach someone to swim. By being thrown into the deep end, Jeannette was given the opportunity to experience the feeling of staying afloat and moving in water. This hands-on experience likely helped her build confidence and learn to swim more effectively over time.
It is important to note that throwing someone into the deep end should only be done under controlled and safe conditions, with the presence of a qualified swimming instructor or a responsible adult who can ensure the person's safety.
