Question

from 1935 to 1943, the traveling librarians of the pack horse library project brought the joy of reading to remote areas in the mountains of kentucky. the librarians, usually women, rode their own horses and mules. in their saddlebags, they carried used books and magazines donated by people from around the country. each route covered eighteen to twenty miles, winding through creek beds and mountain passes.
text 2
luis soriano was a teacher with a dream: to bring books to poor children in the countryside of colombia. in 1997, he started out with one donkey and seventy books. before long, he added another donkey, affixing wooden bookcases to each animal’s saddle. his traveling library became known as the biblioburro, or \donkey library\ in spanish. later, his collection grew to thousands of books.
which sentence best combines the main, or central, ideas of both texts?
traveling libraries have been used in different places around the world to bring books to people in remote areas.
traveling libraries that were invented in the united states and colombia used to be the way most people got their reading material.
although donkeys were important to traveling libraries in kentucky, horses and mules were instrumental to the biblioburro in colombia.

Explanation:

• Text 1: Pack Horse Library Project (1935 - 1943, Kentucky) used traveling librarians on horses/mules to bring books to remote mountain areas.
• Text 2: Luis Soriano's Biblioburro (1997, Colombia) used donkeys to bring books to poor rural children.
• Analyze options:
• First option: "Traveling libraries have been used in different places around the world to bring books to people in remote areas." This matches both texts (Kentucky and Colombia are different places, both remote/rural areas, and both used traveling libraries to deliver books).
• Second option: "Traveling libraries that were invented in the United States and Colombia used to be the way most people got their reading material." The texts don't say traveling libraries were "invented" in these places, nor that they were the "most" common way for reading material.
• Third option: "Although donkeys were important to traveling libraries in Kentucky, horses and mules were instrumental to the Biblioburro in Colombia." This mixes up the animals (Kentucky used horses/mules, Colombia used donkeys), so it's incorrect.

Answer:

Traveling libraries have been used in different places around the world to bring books to people in remote areas.
