Question

the persistence of memory
none of these geographic misconceptions would be surprising for a student to have on the first day of geography class, but even once weve learned the truth, the errors on our mental maps tend to persist. one reason for this may be that our conceptions of the world are basically summaries of the geography, says cartographer dylan moriarty, who is an interactive designer at the wall street journal. the mental map is a simplification, similar to the subway map of new york city, he says. \the approximation is just more useful and practical.\
our physical experience of the world may come into play as well, robinson says. \i think it must have something to do with both the limits of our observable perception of space and time, and the fact that we are disrupting that constantly with technology and methods of transportation and things that compress those things and make them nonfactors.\
whatever the reason, these mental map errors are so pervasive and stubborn that even professionals have them. a 1985 study of mental world maps found that geographers had the same misconceptions of the relative latitude of cities in north america and europe as everyone else. cartographers arent immune either. the \eastiness\ of south america still surprises nelson sometimes. \i really have to look again at a map and be like, is that really the case?\ he says. \and sure enough it is.\

part b
which detail from the passage best supports the correct answer from part a?

1. \the approximation is just more useful\ (paragraph 11)
2. \compress those things and make them nonfactors\ (paragraph 12)
3. \a 1985 study of mental world maps found\ (paragraph 13)
4. \i really have to look again at a map\ (paragraph 13)

1. they suggest that research regarding the main problem described in the passage may be outdated.
2. they suggest that the main problem described in the passage can be addressed now that it is understood.

Explanation:

To solve this, we analyze each option:

Part A (assuming the question is about the main idea or a detail, but since Part B is about supporting a Part A answer, let's focus on Part B logic):

For a detail to support a Part A answer, it must relate logically. Let's assume Part A options (not fully visible, but focusing on Part B's options):

1. "The approximation is just more useful" (Para 11): Talks about mental maps’ usefulness.
2. "compress those things and make them nonfactors" (Para 12): About simplifying with technology.
3. "A 1985 study of mental world maps found" (Para 13): Shows persistence of misconceptions (since even professionals had them).
4. "I really have to look again at a map" (Para 13): Shows surprise at map reality, related to misconceptions.

If Part A is about persistence of mental map errors, then option 3 ("A 1985 study...") supports it by showing even professionals (who should know better) had the same misconceptions, proving pervasiveness.

To determine the supporting detail, we match the Part A claim (likely about persistent mental map errors) with Part B options. The 1985 study (option 3) shows even professionals had misconceptions, supporting the idea of pervasive, stubborn errors.

Answer:

1. (Paragraph 13) "A 1985 study of mental world maps found"
