Jehovah's Witnesses are best known for their door-to-door preaching, distributing literature such as The Watchtower and Awake!, and refusing military service and blood transfusions. They consider use of the name Jehovah vital for proper worship. They reject Trinitarianism, inherent immortality of the soul, and hellfire, which they consider to be unscriptural doctrines. They do not observe Christmas, Easter, birthdays or other holidays and customs they consider to have pagan origins incompatible with Christianity. Adherents commonly refer to their body of beliefs as "the truth" and consider themselves to be "in the truth". They consider secular society to be morally corrupt and under the influence of Satan, and most limit their social interaction with non-Witnesses. Congregational disciplinary actions include disfellowshipping, their term for formal expulsion and shunning. Baptized individuals who formally leave are considered disassociated and are also shunned. Disfellowshipped and disassociated individuals may eventually be reinstated if deemed repentant.
What do Jehovah Witnesses consider the name Jehovah vital for?
****
The answer: proper worship

In 1874, telegraph message traffic was rapidly expanding and in the words of Western Union President William Orton, had become "the nervous system of commerce". Orton had contracted with inventors Thomas Edison and Elisha Gray to find a way to send multiple telegraph messages on each telegraph line to avoid the great cost of constructing new lines. When Bell mentioned to Gardiner Hubbard and Thomas Sanders that he was working on a method of sending multiple tones on a telegraph wire using a multi-reed device, the two wealthy patrons began to financially support Bell's experiments. Patent matters would be handled by Hubbard's patent attorney, Anthony Pollok.
Thomas Edison and what other scientist were already asked to work on a better telegraph?
****
The answer: Elisha Gray

The problem: Answer a question about this article:
A further complication is that the measurement of p involves the measurement of an electric current: this is invariably measured in conventional amperes rather than in SI amperes, so a conversion factor is required. The symbol p-90 is used for the measured gyromagnetic ratio using conventional electrical units. In addition, there are two methods of measuring the value, a "low-field" method and a "high-field" method, and the conversion factors are different in the two cases. Only the high-field value p-90(hi) is of interest in determining the Planck constant.
Why is the measurement of electric current an issue in the estimate of the gyromagnetic ratio?
****
The answer: electric current: this is invariably measured in conventional amperes rather than in SI amperes

Soon after the passing of the 1931 Act, in the book published on the occasion of the Institute's centenary celebration in 1934, Harry Barnes, FRIBA, Chairman of the Registration Committee, mentioned that ARCUK could not be a rival of any architectural association, least of all the RIBA, given the way ARCUK was constituted. Barnes commented that the Act's purpose was not protecting the architectural profession, and that the legitimate interests of the profession were best served by the (then) architectural associations in which some 80 per cent of those practising architecture were to be found.
Who was the head of the Registration Committee in 1934?
****
The answer:
Harry Barnes
