Pg 514 (446) - Q19
“Gambatte” is the word of encouragement given to sons to have courage and be like the carp and swim upstream, while “Kiotsukete” is the caution to daughters to be careful, modest, and safe. This male vs. female distinction is one between perseverance (like the carp) on the sons’ part and prudence and reserve on the daughters’ part, so E is correct.
