Though Meg struggles with being different from the other kids at school and often finds herself in trouble for questioning her teachers she is able to use her intellect to help save her father. Is this an effective topic sentence? Why or why not?

At school, Meg used her intellect to succeed academically, but her social skills were lacking. Intellectually, she was superior to most of her classmates, but this made her an outsider. On Camazotz, Meg tried to use her intellect to block out IT, reciting poems, facts, and so on. She was able to temporarily keep IT out, but it did not help her to rescue her father or Charles Wallace. Mrs. Whats-It told her that her gift was her faults, which were her anger and her impatience. These emotions helped her more than her intellect. Charles Wallace believed that his intellect would protect him if he entered into IT, but he was quickly overcome. Meg knew that her intellect was far inferior to that of Charles Wallace, and so this was not the weapon that would defeat IT. In the end, it was her love for her father and for Charles Wallace that rescued them. Meg realized that this is one thing that IT did not have and could not understand, since it was pure intellect. She had the power to love.
Therefore, this is not an effective topic sentence, since it is not how she rescued her father or Charles Wallace. It was her emotions, rather than her intellect, that helped her.
