Problem: Montevideo:

Parque Batlle is named in honour of José Batlle y Ordóñez, President of Uruguay from 1911 to 1915. The park was originally proposed by an Act of March 1907, which also projected wide boulevards and avenues. French landscape architect, Carlos Thays, began the plantings in 1911. In 1918, the park was named Parque de los Aliados, following the victory of the Allies of World War I. On 5 May 1930, after significant expansion, it was again renamed as Parque Batlle y Ordóñez, in memory of the prominent politician and president, who had died in 1929. The park was designated a National Historic Monument Park in 1975. As of 2010[update], the park covers an area of 60 hectares (150 acres) and is considered the "lung" of the Montevideo city due to the large variety of trees planted here.

Problem: Hydrogen:

Hydrogen is employed to saturate broken ("dangling") bonds of amorphous silicon and amorphous carbon that helps stabilizing material properties. It is also a potential electron donor in various oxide materials, including ZnO, SnO2, CdO, MgO, ZrO2, HfO2, La2O3, Y2O3, TiO2, SrTiO3, LaAlO3, SiO2, Al2O3, ZrSiO4, HfSiO4, and SrZrO3.

How is hydrogen used in oxide materials?

Problem: Dwight D. Eisenhower:

The last three years of Eisenhower's second term in office were ones of relatively good health. Eventually after leaving the White House, he suffered several additional and ultimately crippling heart attacks. A severe heart attack in August 1965 largely ended his participation in public affairs. In August 1966 he began to show symptoms of cholecystitis, for which he underwent surgery on December 12, 1966, when his gallbladder was removed, containing 16 gallstones. After Eisenhower's death in 1969 (see below), an autopsy unexpectedly revealed an adrenal pheochromocytoma, a benign adrenaline-secreting tumor that may have made the President more vulnerable to heart disease. Eisenhower suffered seven heart attacks in total from 1955 until his death.

What did Eisenhower have removed via surgery on December 12, 1966?

A:
gallbladder
