What was the latter teaching school or opening up a school, Context: Unsure of his future, he first contemplated returning to London to complete his studies, but decided to return to Boston as a teacher. His father helped him set up his private practice by contacting Gardiner Greene Hubbard, the president of the Clarke School for the Deaf for a recommendation. Teaching his father's system, in October 1872, Alexander Bell opened his "School of Vocal Physiology and Mechanics of Speech" in Boston, which attracted a large number of deaf pupils, with his first class numbering 30 students. While he was working as a private tutor, one of his most famous pupils was Helen Keller, who came to him as a young child unable to see, hear, or speak. She was later to say that Bell dedicated his life to the penetration of that "inhuman silence which separates and estranges." In 1893, Keller performed the sod-breaking ceremony for the construction of the new Bell's new Volta Bureau, dedicated to "the increase and diffusion of knowledge relating to the deaf".

What ties together spiritual leader and editor?, Context: According to the New Jersey Press Association, several media entities refrain from using the term "ultra-Orthodox", including the Religion Newswriters Association; JTA, the global Jewish news service; and the Star-Ledger, New Jersey’s largest daily newspaper. The Star-Ledger was the first mainstream newspaper to drop the term. Several local Jewish papers, including New York's Jewish Week and Philadelphia's Jewish Exponent have also dropped use of the term. According to Rabbi Shammai Engelmayer, spiritual leader of Temple Israel Community Center in Cliffside Park and former executive editor of Jewish Week, this leaves "Orthodox" as "an umbrella term that designates a very widely disparate group of people very loosely tied together by some core beliefs."

How does the process that kills duramen start?, Context: Heartwood (or duramen) is wood that as a result of a naturally occurring chemical transformation has become more resistant to decay. Heartwood formation occurs spontaneously (it is a genetically programmed process). Once heartwood formation is complete, the heartwood is dead. Some uncertainty still exists as to whether heartwood is truly dead, as it can still chemically react to decay organisms, but only once.
