Input: Consider Input: Passage: Uranium is a naturally occurring element that can be found in low levels within all rock, soil, and water. Uranium is the 51st element in order of abundance in the Earth's crust. Uranium is also the highest-numbered element to be found naturally in significant quantities on Earth and is almost always found combined with other elements. Along with all elements having atomic weights higher than that of iron, it is only naturally formed in supernovae. The decay of uranium, thorium, and potassium-40 in the Earth's mantle is thought to be the main source of heat that keeps the outer core liquid and drives mantle convection, which in turn drives plate tectonics. Question: Where does uranium rank among elements in terms of its abundance in the Earth's crust?

Output: 51st


Input: Consider Input: Passage: As early as 1650, settlers from the Virginia colony moved into the area of Albemarle Sound. By 1663, King Charles II of England granted a charter to start a new colony on the North American continent; it generally established North Carolina's borders.

Output: 1663

The ballroom wing and a further suite of state rooms were also built in this period, designed by Nash's student Sir James Pennethorne. Question: Who designed a new wing for Queen Victoria and Prince Albert when they felt they needed more space?
