Final answer:
The inclusion of suspense before Mark plays the violin aims to highlight the importance of the performance. Suspense increases emotional engagement and signals the significance of the upcoming event, making the audience more invested in the outcome.
Step-by-step explanation:
The purpose of including suspense before Mark plays the violin is to show how important this performance is. Suspense is often used to build emotional intensity, set the tone, and emphasize the significance of what is about to transpire, much like a film's music cues the audience to the emotional context of a scene. In the context of a performance, suspense can be a tool to signal to the audience that what they are about to witness has considerable significance to the characters involved.
Take for example a scene in a theater: slow, dissonant melodies in a minor key heralding the appearance of a new character can create a sense of dread. Similarly, when an audience is aware that a live, important performance is about to start, and the performer shows signs of anxiety or there's a palpable tension in the air, the audience's engagement and anticipation heighten. The importance placed on Mark's performance could be sensed through the nervous energy that a suspenseful atmosphere creates.
Therefore, while other options might be plausible, the emphasis on the significance of the moment is a key reason for the use of suspense in a narrative. It draws the audience in and makes them more emotionally invested in the outcome of the performance.
