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.
the realization helps him figure out the location of the maravilha.

Explanation:

1. Analyze Option 1: The text doesn't focus on his mother's communication style in relation to "people don't change"—it's about her scientific process, so this is incorrect.
2. Analyze Option 2: The mission planners assumed she found Maravilha when she announced, but Alberto knows she tests repeatedly (because "people don't change"—she still follows her old, thorough process). So his realization explains why she hasn't announced (and thus others think she hasn't discovered, but she has been studying it). Wait, no—wait, the question is why the realization is significant. Wait, let's re - read. The passage says "the mission planners assumed that's when she'd found the Maravilha, because standard practice was to announce discoveries immediately. But people don't change. Alberto knew that his mother never announced anything until she had tested...". So his mother's process (not changing) means she had been studying Maravilha for months before announcement. But the option says "explains why his mother hasn't yet discovered Maravilha"—but she had discovered it, just not announced. So this is wrong.
3. Analyze Option 3: The text says she tests her findings repeatedly, not that she isn't sure about properties. So this is incorrect.
4. Analyze Option 4: Alberto realizes his mother's process (because people don't change) is to test thoroughly. So he knows she has been studying Maravilha in her lab (since she hasn't announced yet, so she's still testing). So he races to her lab, which is the location of Maravilha (since she's studying it there). So the realization helps him figure out the location (her lab) of Maravilha.

Wait, let's re - evaluate. Let's check each option again:

• Option 1: The passage has no mention of her communication style being related to "people don't change"—she snapped, but that's a single instance, not related to the "people don't change" about her work process. Eliminate.
• Option 2: The text says she had found Maravilha (she was studying it in her lab), she just didn't announce. So the realization is not about why she hasn't discovered, but why she hasn't announced. So this is incorrect.
• Option 3: The text says she tests, retests, triple - tests—she is sure, she just doesn't announce. So this is incorrect.
• Option 4: Since she doesn't change, she follows her old process of studying in her lab before announcing. So Alberto realizes she must be studying Maravilha in her lab, so he goes there—so the realization helps him figure out the location (her lab) of Maravilha. This makes sense.

Answer:

The realization helps him figure out the location of the Maravilha.
