Context and question: Although initially thought to have originated as a manmade variant of an extant canid species (variously supposed as being the dhole, golden jackal, or gray wolf), extensive genetic studies undertaken during the 2010s indicate that dogs diverged from an extinct wolf-like canid in Eurasia 40,000 years ago. Being the oldest domesticated animal, their long association with people has allowed dogs to be uniquely attuned to human behavior, as well as thrive on a starch-rich diet which would be inadequate for other canid species.
What was undertaken in 2010 to determine where dogs originated from?
Answer: extensive genetic studies
Context and question: The length of the pitch for international adult matches is in the range of 100110 m (110120 yd) and the width is in the range of 6475 m (7080 yd). Fields for non-international matches may be 90120 m (100130 yd) length and 4590 m (50100 yd) in width, provided that the pitch does not become square. In 2008, the IFAB initially approved a fixed size of 105 m (344 ft) long and 68 m (223 ft) wide as a standard pitch dimension for international matches; however, this decision was later put on hold and was never actually implemented.
What is the length of the pitch for international child matches?
Answer: unanswerable

Manufacturing consists largely of the production of specialist chemicals, health and pharmaceutical goods, scientific and precision measuring instruments and musical instruments. The largest exported goods are chemicals (34% of exported goods), machines/electronics (20.9%), and precision instruments/watches (16.9%). Exported services amount to a third of exports. The service sector especially banking and insurance, tourism, and international organisations is another important industry for Switzerland.
What accounts for 16.9% of Switzerland's exported goods?
