Final answer:
A growth mindset contributes to a person's grit as it instills a desire to learn and persevere through challenges, directly affecting one's resilience and capacity to overcome setbacks.
Step-by-step explanation:
A growth mindset plays a crucial role in developing a person's grit or resilience. Someone with a growth mindset believes in their ability to learn and improve through effort and perseverance. This view aligns directly with the essence of grit, which is personal perseverance toward a task or goal.
As opposed to a fixed mindset, which suggests intelligence and talent are static, a growth mindset propels individuals to embrace challenges, learn from criticism, and persist in the face of setbacks. Consequently, those who approach life with a growth mindset are more willing to face challenges and learn from them, which directly contributes to increased grit. This explains why option B is correct: A desire to learn will help overcome failure and allow the person to persevere.
