When a house straddles Belgium and the Netherlands, what usually determines its official country?

  1. Where the kitchen sits
  2. Where the front door stands
  3. Which side has more floor space

Sources: Municipality of Baarle-Hertog and Omroep Brabant.

Show the answer, explanation, and sources

Answer: Chimborazo. Chimborazo is farther from Earth's center than Everest.

Ecuador's Chimborazo stands near the Equator, where Earth bulges outward. Its summit is therefore about 2.1 kilometers farther from Earth's center than Everest's.

Show the answer, explanation, and sources

Answer: Farther east. The Pacific entrance lies east of the Atlantic entrance.

Panama curves in a broad S shape, and the canal runs from northwest to southeast. Ships traveling from the Atlantic toward the Pacific therefore finish farther east.
