PROBLEM: The United States presidential line of succession is the order in which persons may become or act as President of the United States if the incumbent President becomes incapacitated, dies, resigns or is removed from office. (A President can be removed from office by impeachment by the House of Representatives and subsequent conviction by the Senate.) The line of succession is set by the United States Constitution and the Presidential Succession Act of 1947 as subsequently amended to include newly created cabinet offices. The succession follows the order of Vice President, Speaker of the House of Representatives, President pro tempore of the Senate, and then the heads of federal executive departments who form the Cabinet of the United States, which currently has fifteen members, beginning with the Secretary of State. Those heads of departments who are ineligible to act as President are also ineligible to succeed the President by succession, for example most commonly if they are not a natural-born U.S. citizen.

SOLUTION: who is the fourth person in the line of succession for the presidency

PROBLEM: Glass is a non-crystalline amorphous solid that is often transparent and has widespread practical, technological, and decorative usage in, for example, window panes, tableware, and optoelectronics. The most familiar, and historically the oldest, types of glass are 'silicate glasses' based on the chemical compound silica (silicon dioxide, or quartz), the primary constituent of sand. The term glass, in popular usage, is often used to refer only to this type of material, which is familiar from use as window glass and in glass bottles. Of the many silica-based glasses that exist, ordinary glazing and container glass is formed from a specific type called soda-lime glass, composed of approximately 75% silicon dioxide (SiO), sodium oxide (Na O) from sodium carbonate (Na CO), calcium oxide (CaO), also called lime, and several minor additives.

SOLUTION:
name two articles that can be made from glass
