[EX Q]: How does a chestnut tree form its heartwood?, Context: The term heartwood derives solely from its position and not from any vital importance to the tree. This is evidenced by the fact that a tree can thrive with its heart completely decayed. Some species begin to form heartwood very early in life, so having only a thin layer of live sapwood, while in others the change comes slowly. Thin sapwood is characteristic of such species as chestnut, black locust, mulberry, osage-orange, and sassafras, while in maple, ash, hickory, hackberry, beech, and pine, thick sapwood is the rule. Others never form heartwood.

[EX Q]: Which of the following is not the name of a goddess: Taleju, Durga, or Kumari?, Context: Kumari Ghar is a palace in the center of the Kathmandu city, next to the Durbar square where a Royal Kumari selected from several Kumaris resides. Kumari, or Kumari Devi, is the tradition of worshipping young pre-pubescent girls as manifestations of the divine female energy or devi in South Asian countries. In Nepal the selection process is very rigorous. Kumari is believed to be the bodily incarnation of the goddess Taleju (the Nepali name for Durga) until she menstruates, after which it is believed that the goddess vacates her body. Serious illness or a major loss of blood from an injury are also causes for her to revert to common status. The current Royal Kumari, Matina Shakya, age four, was installed in October 2008 by the Maoist government that replaced the monarchy.
[EX A]: Kumari
