How did Emma's heart rate respond after spelling the word correctly?

• A. It returned to normal immediately
• B. It continued racing
• C. It slowed down significantly
• D. It fluctuated rapidly

Answer: (B)

When Emma spelled the word correctly, her heart rate continued racing. This response can be understood as a physiological reaction to stress or excitement. During challenging situations, such as a spelling test, the body often experiences heightened adrenaline levels, leading to an increased heart rate even after the stressful event is resolved. Although one might expect the heart rate to return to normal immediately after completing a task successfully, the residual excitement or anxiety from the experience can prolong an elevated heart rate. Therefore, option B is correct as it accurately reflects the continuing effect of adrenaline and adrenaline's impact on heart rate after a moment of tension and achievement.
