TASK DEFINITION: In this task you will be given an answer to a question. You need to generate a question. The answer given should be a correct answer for the generated question.
PROBLEM: The election of President and Vice President of the United States is an indirect election in which citizens of the United States who are registered to vote in one of the 50 U.S. states or Washington, D.C. cast ballots for members of the U.S. Electoral College, known as electors. These electors then in turn cast direct votes, known as electoral votes, for President and Vice President. The candidate who receives an absolute majority of electoral votes for President or Vice President (currently, at least 270 out of a total of 538) is then elected to that office. If no candidate receives an absolute majority for President, the House of Representatives chooses the President; if no one receives a majority for Vice President, then the Senate chooses the Vice President.

SOLUTION: who votes for the president of the united states

PROBLEM: The Chesapeake Bay Bridge -- Tunnel (CBBT) is a 23-mile (37 km) fixed link crossing at the mouth of the Chesapeake Bay in the U.S. state of Virginia. It connects Northampton County on the Delmarva Peninsula with Virginia Beach, which is part of the Hampton Roads metropolitan area. The bridge -- tunnel originally combined 12 miles (19 km) of trestle, two 1-mile-long (1.6 km) tunnels, four artificial islands, four high-level bridges, approximately 2 miles (3.2 km) of causeway, and 5.5 miles (8.9 km) of approach roads -- crossing the Chesapeake Bay and preserving traffic on the Thimble Shoals and Chesapeake shipping channels. It replaced vehicle ferry services that operated from South Hampton Roads and from the Virginia Peninsula from the 1930s. Financed by toll revenue bonds, the bridge -- tunnel was opened on April 15, 1964, and remains one of only ten bridge -- tunnel systems in the world, three of which are located in Hampton Roads, Virginia.

PROBLEM: An aquatic animal is an animal, either vertebrate or invertebrate, which lives in the water for most or all of its lifetime. Many insects such as mosquitoes, mayflies, dragonflies and caddisflies have aquatic larvae, with winged adults. Aquatic animals may breathe air or extract oxygen that dissolved in water through specialised organs called gills, or directly through the skin. Natural environments and the animals that live in them can be categorized as aquatic (water) or terrestrial (land).

SOLUTION:
where do animals and plants get the oxygen from in the aquatic environment
