The Berbers along the Barbary Coast (modern day Libya) sent pirates to capture merchant ships and hold the crews for ransom. The U.S. paid protection money until 1801, when President Thomas Jefferson refused to pay and sent in the Navy to challenge the Barbary States, the First Barbary War followed. After the U.S.S. Philadelphia was captured in 1803, Lieutenant Stephen Decatur led a raid which successfully burned the captured ship, preventing Tripoli from using or selling it. In 1805, after William Eaton captured the city of Derna, Tripoli agreed to a peace treaty. The other Barbary states continued to raid U.S. shipping, until the Second Barbary War in 1815 ended the practice.

Context and question: A cardinal who is not a bishop is still entitled to wear and use the episcopal vestments and other pontificalia (episcopal regalia: mitre, crozier, zucchetto, pectoral cross and ring). Even if not a bishop, any cardinal has both actual and honorary precedence over non-cardinal patriarchs, as well as the archbishops and bishops who are not cardinals, but he cannot perform the functions reserved solely to bishops, such as ordination. The prominent priests who since 1962 were not ordained bishops on their elevation to the cardinalate were over the age of 80 or near to it, and so no cardinal who was not a bishop has participated in recent papal conclaves.
Cardinals who were not bishops have been promoted to Cardinal around the age of 80 since what year?
Answer: 1962

The life cycles of insects vary but most hatch from eggs. Insect growth is constrained by the inelastic exoskeleton and development involves a series of molts. The immature stages can differ from the adults in structure, habit and habitat, and can include a passive pupal stage in those groups that undergo 4-stage metamorphosis (see holometabolism). Insects that undergo 3-stage metamorphosis lack a pupal stage and adults develop through a series of nymphal stages. The higher level relationship of the Hexapoda is unclear. Fossilized insects of enormous size have been found from the Paleozoic Era, including giant dragonflies with wingspans of 55 to 70 cm (22–28 in). The most diverse insect groups appear to have coevolved with flowering plants.
The most diverse insects coevolved with what?
A:
flowering plants
