Input: Samurai
In Japanese, they are usually referred to as bushi (武士?, [bu.ɕi]) or buke (武家?). According to translator William Scott Wilson: "In Chinese, the character 侍 was originally a verb meaning "to wait upon" or "accompany persons" in the upper ranks of society, and this is also true of the original term in Japanese, saburau. In both countries the terms were nominalized to mean "those who serve in close attendance to the nobility", the pronunciation in Japanese changing to saburai. According to Wilson, an early reference to the word "samurai" appears in the Kokin Wakashū (905–914), the first imperial anthology of poems, completed in the first part of the 10th century.

When is the first known use of 'samurai'?

Input: Alexander Graham Bell
Although Bell was, and still is, accused of stealing the telephone from Gray, Bell used Gray's water transmitter design only after Bell's patent had been granted, and only as a proof of concept scientific experiment, to prove to his own satisfaction that intelligible "articulate speech" (Bell's words) could be electrically transmitted. After March 1876, Bell focused on improving the electromagnetic telephone and never used Gray's liquid transmitter in public demonstrations or commercial use.

Bell stopped using the liquid-based method after what month?
Output: March

Input: War on Terror
In September 2009, a U.S. Drone strike reportedly killed Ilyas Kashmiri, who was the chief of Harkat-ul-Jihad al-Islami, a Kashmiri militant group associated with Al-Qaeda. Kashmiri was described by Bruce Riedel as a 'prominent' Al-Qaeda member, while others described him as the head of military operations for Al-Qaeda. Waziristan had now become the new battlefield for Kashmiri militants, who were now fighting NATO in support of Al-Qaeda. On 8 July 2012, Al-Badar Mujahideen, a breakaway faction of Kashmir centric terror group Hizbul Mujahideen, on conclusion of their two-day Shuhada Conference called for mobilisation of resources for continuation of jihad in Kashmir.

Input: Wood
Heartwood is often visually distinct from the living sapwood, and can be distinguished in a cross-section where the boundary will tend to follow the growth rings. For example, it is sometimes much darker. However, other processes such as decay or insect invasion can also discolor wood, even in woody plants that do not form heartwood, which may lead to confusion.

In what part of a tree's cross-section is heartwood visible?
Output:
growth rings
