PSAT/SAT Quiz

In 2007, computer scientist Luis von Ahn was working on converting printed books into a digital format. He found that some words were distorted enough that digital scanners couldn’t recognize them, but most humans could easily read them. Based on that finding, von Ahn invented a simple security test to keep automated “bots” out of websites. The first version of the reCAPTCHA test asked users to type one known word and one of the many words scanners couldn’t recognize. Correct answers proved the users were humans and added data to the book-digitizing project. Which choice best states the main purpose of the text?

• To discuss von Ahn’s invention of reCAPTCHA

• To explain how digital scanners work

• To call attention to von Ahn’s book-digitizing project

• To indicate how popular reCAPTCHA is

In the mountains of Brazil, Barbacenia tomentosa and Barbacenia macrantha—two plants in the Velloziaceae family—establish themselves on soilless, nutrient-poor patches of quartzite rock. Plant ecologists Anna Abrahão and Patricia de Britto Costa used microscopic analysis to determine that the roots of B. tomentosa and B. macrantha, which grow directly into the quartzite, have clusters of fine hairs near the root tip; further analysis indicated that these hairs secrete both malic and citric acids. The researchers hypothesize that the plants depend on dissolving underlying rock with these acids, as the process not only creates channels for continued growth but also releases phosphates that provide the vital nutrient phosphorus. Which finding, if true, would most directly support the researchers’ hypothesis?

• Other species in the Velloziaceae family are found in terrains with more soil but have root structures similar to those of B. tomentosa and B. macrantha.

• Though B. tomentosa and B. macrantha both secrete citric and malic acids, each species produces the acids in different proportions.

• The roots of B. tomentosa and B. macrantha carve new entry points into rocks even when cracks in the surface are readily available.

• B. tomentosa and B. macrantha thrive even when transferred to the surfaces of rocks that do not contain phosphates.
