Ex Input:
Official Catholic accounts state that the Virgin Mary appeared four times before Juan Diego and one more before Juan Diego's uncle. According to these accounts the first apparition occurred on the morning of December 9, 1531, when a native Mexican peasant named Juan Diego saw a vision of a maiden at a place called the Hill of Tepeyac, which would become part of Villa de Guadalupe, a suburb of Mexico City. Speaking to Juan Diego in his native Nahuatl language (the language of the Aztec empire), the maiden identified herself as the Virgin Mary, 'mother of the very true deity' and asked for a church to be built at that site in her honor.

Ex Output:
who did our lady of guadalupe appeared to


Ex Input:
Mount Rushmore National Memorial is a sculpture carved into the granite face of Mount Rushmore, a batholith in the Black Hills in Keystone, South Dakota, United States. Sculptor Gutzon Borglum created the sculpture's design and oversaw the project's execution from 1927 to 1941 with the help of his son, Lincoln Borglum. Mount Rushmore features 60-foot (18 m) sculptures of the heads of four United States presidents: George Washington (1732 -- 1799), Thomas Jefferson (1743 -- 1826), Theodore Roosevelt (1858 -- 1919), and Abraham Lincoln (1809 -- 1865). The memorial park covers 1,278.45 acres (2.00 sq mi; 5.17 km) and is 5,725 feet (1,745 m) above sea level.

Ex Output:
name of the four presidents on mount rushmore


Ex Input:
Temperature is a monotonic function of the average molecular kinetic energy of a substance. When a substance is heated, the kinetic energy of its molecules increases. Thus, the molecules begin vibrating / moving more and usually maintain a greater average separation. Materials which contract with increasing temperature are unusual; this effect is limited in size, and only occurs within limited temperature ranges (see examples below). The relative expansion (also called strain) divided by the change in temperature is called the material's coefficient of thermal expansion and generally varies with temperature.

Ex Output:

what does a high coefficient of thermal expansion mean
