Problem: Once the elevator arrives at the floor, it will park with its doors open and the car buttons will be disabled to prevent a passenger from taking control of the elevator. Medical personnel must then activate the code-blue key switch inside the car, select their floor and close the doors with the door close button. The elevator will then travel non-stop to the selected floor, and will remain in code-blue service until switched off in the car. Some hospital elevators will feature a 'hold' position on the code-blue key switch (similar to fire service) which allows the elevator to remain at a floor locked out of service until code blue is deactivated.
What does the hold feature do?
The answer is the following: allows the elevator to remain at a floor locked out of service until code blue is deactivated

Problem: Baptists, like other Christians, are defined by doctrinesome of it common to all orthodox and evangelical groups and a portion of it distinctive to Baptists. Through the years, different Baptist groups have issued confessions of faithwithout considering them to be creedsto express their particular doctrinal distinctions in comparison to other Christians as well as in comparison to other Baptists. Most Baptists are evangelical in doctrine, but Baptist beliefs can vary due to the congregational governance system that gives autonomy to individual local Baptist churches. Historically, Baptists have played a key role in encouraging religious freedom and separation of church and state.
Baptists have issued what without considering them to be creeds?
The answer is the following: confessions of faith

Problem: Modified radicals and new variants are two common reasons for the ever-increasing number of characters. There are about 300 radicals and 100 are in common use. Creating a new character by modifying the radical is an easy way to disambiguate homographs among xingshengzi pictophonetic compounds. This practice began long before the standardization of Chinese script by Qin Shi Huang and continues to the present day. The traditional 3rd-person pronoun ta ( "he, she, it"), which is written with the "person radical", illustrates modifying significs to form new characters. In modern usage, there is a graphic distinction between ta ( "she") with the "woman radical", ta ( "it") with the "animal radical", ta ( "it") with the "roof radical", and ta ( "He") with the "deity radical", One consequence of modifying radicals is the fossilization of rare and obscure variant logographs, some of which are not even used in Classical Chinese. For instance, he "harmony, peace", which combines the "grain radical" with the "mouth radical", has infrequent variants with the radicals reversed and with the "flute radical".
What is one consequence of modifying radicals?
The answer is the following: fossilization

Problem: Neptune has 14 known moons. Triton is the largest Neptunian moon, comprising more than 99.5% of the mass in orbit around Neptune,[e] and it is the only one massive enough to be spheroidal. Triton was discovered by William Lassell just 17 days after the discovery of Neptune itself. Unlike all other large planetary moons in the Solar System, Triton has a retrograde orbit, indicating that it was captured rather than forming in place; it was probably once a dwarf planet in the Kuiper belt. It is close enough to Neptune to be locked into a synchronous rotation, and it is slowly spiralling inward because of tidal acceleration. It will eventually be torn apart, in about 3.6 billion years, when it reaches the Roche limit. In 1989, Triton was the coldest object that had yet been measured in the Solar System, with estimated temperatures of 38 K (235 C).
What does Triton's orbit suggest about it's relation to Neptune?
The answer is the following:
that it was captured
