Here is a question about this article: In addition to the call buttons, elevators usually have floor indicators (often illuminated by LED) and direction lanterns. The former are almost universal in cab interiors with more than two stops and may be found outside the elevators as well on one or more of the floors. Floor indicators can consist of a dial with a rotating needle, but the most common types are those with successively illuminated floor indications or LCDs. Likewise, a change of floors or an arrival at a floor is indicated by a sound, depending on the elevator.
What is the answer to this question: Modern elevator position or floor indicaters often use what type of bulbs?
****

Question: Read this and answer the question

Anthocyanins tend to be the main polyphenolics in purple grapes whereas flavan-3-ols (i.e. catechins) are the more abundant phenolic in white varieties. Total phenolic content, a laboratory index of antioxidant strength, is higher in purple varieties due almost entirely to anthocyanin density in purple grape skin compared to absence of anthocyanins in white grape skin. It is these anthocyanins that are attracting the efforts of scientists to define their properties for human health. Phenolic content of grape skin varies with cultivar, soil composition, climate, geographic origin, and cultivation practices or exposure to diseases, such as fungal infections.

What are the most abundant polyphenolics in purple grapes?
Answer: Anthocyanins

Problem: Ruling elders are usually laymen (and laywomen in some denominations) who are elected by the congregation and ordained to serve with the teaching elders, assuming responsibility for nurture and leadership of the congregation. Often, especially in larger congregations, the elders delegate the practicalities of buildings, finance, and temporal ministry to the needy in the congregation to a distinct group of officers (sometimes called deacons, which are ordained in some denominations).

Who elects the ruling elders?
The answer is the following: the congregation
