Question

13 that thought pestered him. people dont change. his mission had targeted november, when dr. quavious announced her findings. the mission planners assumed thats when shed found the maravilha, because standard practice was to announce discoveries immediately. but people dont change. alberto knew that his mother never announced anything until she had tested, retested, and triple - tested her findings. she would have studied maravilha in her laboratory for months before her announcement. that meant—
14 alberto raced back to his moms lab. his father didnt look up as alberto dashed past the briefing room toward the door labeled dr. quavious: private. he knocked, entering before she answered. \excuse me,\ she snapped.

why is it significant that alberto realizes people dont change?

the realization helps him accept his mothers sometimes - harsh communication style.

the realization explains why his mother hasnt yet discovered maravilha.

the realization explains why his mother isnt yet sure about the properties of maravilha.

Explanation:

1. Analyze the first option: The text shows Alberto's mother has a harsh communication style (she snapped at him), and his realization that "people don't change" connects to accepting her consistent communication style, as her behavior (like harshness) is part of her unchanging nature.
2. Analyze the second option: The text says the mission planners assumed she found Maravilha when she announced, but Alberto realizes she had already found it and was testing, so this option is incorrect as she did discover it.
3. Analyze the third option: The text shows she was testing her findings, not that she wasn't sure about properties; she was just following her unchanging process of testing, so this is incorrect.

Answer:

The realization helps him accept his mother's sometimes - harsh communication style.
