17. The passage given below is followed by four alternate summaries. Choose the option that best captures the essence of the passage. Cartographers design and create maps to communicate information about phenomena located somewhere on our planet. In the past, cartographers did not worry too much about who was going to read their maps. Although some simple “usability” research was done—like comparing whether circle or bar symbols worked best—cartographers knew how to make maps. This has changed now, however, due to all kinds of societal and technological developments. Today, map readers are more demanding—mostly because of the tools they use to read maps. Cartographers, who are also influenced by these trends, are now more interested in seeing if their products are efficient, effective, and appreciated.

Correct answer: A
A para-summary: the winning option states the main point and the cause the paragraph gives for it.
Main point. Cartographers used to not worry much about who read their maps. That has changed: "due to all kinds of societal and technological developments," readers are now more demanding — largely because of the tools they use — so cartographers now care whether their maps are efficient, effective and appreciated (i.e. usable).
Why A is right. "Today, cartographers also need to look into the usability of maps because of the new technological developments" states both the shift (usability now matters) and its cause (technological developments).
Why the others fail.
- B adds "through a series of experiments" — the passage never says cartographers run experiments; that detail is unsupported.
- C keeps only the readers-are-more-demanding half and drops the cartographers' usability response and the technological cause.
- D reframes the change as cartographers "experimenting with innovations," but the point is reader usability, not playing with new technology.
Answer: A
