Final answer:
Stella's arrival at Agro Global Headquarters intensifies suspense by using literary devices that suggest upcoming revelations and create a foreboding atmosphere.
Step-by-step explanation:
The arrival of Stella at Agro Global Headquarters in paragraphs 28 to 30 serves as a crucial moment in building suspense as it sets the stage for the climax of the story. The anticipation is heightened through various literary techniques such as the introduction of fingerspelling, which suggests the arrival of an important message or revelation.
The narrative's tone, shifting to one potentially overwhelming with exposure to grim perspectives, primes the reader to feel a mix of emotions, including anxiety and excitement. These emotions grip the reader as they wait to see what Stella's arrival will mean for the unfolding events.
Moreover, descriptions such as the dark settings and violent winds further emphasize the tension and foreboding atmosphere.
