Analyse narrative et physiologique : roman et nouvelle

Read the following excerpt: 'The parlor remained silent. Clara observed her brother, Arthur, sitting like a stone figure, showing no sign of emotion. She could not perceive the internal storm that consumed him; his internal pulse had spiked to $144\,beats/min$, far above his baseline resting state of $72\,beats/min$.' 1. Identify the focalization types employed for Clara and Arthur respectively. 2. Analyze how the disparity between the two focalizations creates narrative tension. 3. Calculate the intensity of Arthur's physiological response as a percentage increase relative to his resting heart rate, using the formula P = \left( \\frac{HR_{stressed} - HR_{resting}}{HR_{resting}} \\right) \times 100.
