Article: The earliest known macrofossil confidently identified as an angiosperm, Archaefructus liaoningensis, is dated to about 125 million years BP (the Cretaceous period), whereas pollen considered to be of angiosperm origin takes the fossil record back to about 130 million years BP. However, one study has suggested that the early-middle Jurassic plant Schmeissneria, traditionally considered a type of ginkgo, may be the earliest known angiosperm, or at least a close relative. In addition, circumstantial chemical evidence has been found for the existence of angiosperms as early as 250 million years ago. Oleanane, a secondary metabolite produced by many flowering plants, has been found in Permian deposits of that age together with fossils of gigantopterids. Gigantopterids are a group of extinct seed plants that share many morphological traits with flowering plants, although they are not known to have been flowering plants themselves.

Question: What pushes the age of angiosperm 5 million years further back?
Ans: pollen


Article: While Dutch generally refers to the language as a whole, Belgian varieties are sometimes collectively referred to as Flemish. In both Belgium and the Netherlands, the native official name for Dutch is Nederlands, and its dialects have their own names, e.g. Hollands "Hollandish", West-Vlaams "Western Flemish", Brabants "Brabantian". The use of the word Vlaams ("Flemish") to describe Standard Dutch for the variations prevalent in Flanders and used there, however, is common in the Netherlands and Belgium.

Question: What are variations on Dutch used in Belgium sometimes called?
Ans: Flemish


Article: Paleoptera and Neoptera are the winged orders of insects differentiated by the presence of hardened body parts called sclerites, and in the Neoptera, muscles that allow their wings to fold flatly over the abdomen. Neoptera can further be divided into incomplete metamorphosis-based (Polyneoptera and Paraneoptera) and complete metamorphosis-based groups. It has proved difficult to clarify the relationships between the orders in Polyneoptera because of constant new findings calling for revision of the taxa. For example, the Paraneoptera have turned out to be more closely related to the Endopterygota than to the rest of the Exopterygota. The recent molecular finding that the traditional louse orders Mallophaga and Anoplura are derived from within Psocoptera has led to the new taxon Psocodea. Phasmatodea and Embiidina have been suggested to form the Eukinolabia. Mantodea, Blattodea, and Isoptera are thought to form a monophyletic group termed Dictyoptera.

Question: Paleoptera and Neoptera are what kind of insect orders? 
Ans: winged


Article: Non-commercial radio stations include NPR affiliates KUOW-FM 94.9 and KPLU-FM 88.5 (Tacoma), as well as classical music station KING-FM 98.1. Other stations include KEXP-FM 90.3 (affiliated with the UW), community radio KBCS-FM 91.3 (affiliated with Bellevue College), and high school radio KNHC-FM 89.5, which broadcasts an electronic dance music radio format and is owned by the public school system and operated by students of Nathan Hale High School. Many Seattle radio stations are also available through Internet radio, with KEXP in particular being a pioneer of Internet radio. Seattle also has numerous commercial radio stations. In a March 2012 report by the consumer research firm Arbitron, the top FM stations were KRWM (adult contemporary format), KIRO-FM (news/talk), and KISW (active rock) while the top AM stations were KOMO (AM) (all news), KJR (AM) (all sports), KIRO (AM) (all sports).

Question: What radio station is operated by the public school system?
Ans:
KNHC-FM 89.5
