In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

Q: What distinct theme do metaphors contain from a piece of writing or conversation?, Context: The term heresy is also used as an ideological pigeonhole for contemporary writers because, by definition, heresy depends on contrasts with an established orthodoxy. For example, the tongue-in-cheek contemporary usage of heresy, such as to categorize a "Wall Street heresy" a "Democratic heresy" or a "Republican heresy," are metaphors that invariably retain a subtext that links orthodoxies in geology or biology or any other field to religion. These expanded metaphoric senses allude to both the difference between the person's views and the mainstream and the boldness of such a person in propounding these views.

A: subtext

Q: What are lifts?, Context: Stage lifts and orchestra lifts are specialized elevators, typically powered by hydraulics, that are used to raise and lower entire sections of a theater stage. For example, Radio City Music Hall has four such elevators: an orchestra lift that covers a large area of the stage, and three smaller lifts near the rear of the stage. In this case, the orchestra lift is powerful enough to raise an entire orchestra, or an entire cast of performers (including live elephants) up to stage level from below. There's a barrel on the background of the image of the left which can be used as a scale to represent the size of the mechanism

A: specialized elevators, typically powered by hydraulics, that are used to raise and lower entire sections of a theater stage

Q: How do you write Chinese characters?, Context: Examples are he "river", hu "lake", liu "stream", chong "riptide" (or "flush"), hua "slippery". All these characters have on the left a radical of three short strokes (), which is a reduced form of the character shui meaning "water", indicating that the character has a semantic connection with water. The right-hand side in each case is a phonetic indicator. For example, in the case of chong (Old Chinese *-lju), the phonetic indicator is zhong (Old Chinese *k-lju), which by itself means "middle". In this case it can be seen that the pronunciation of the character is slightly different from that of its phonetic indicator; the process of historical phonetic change means that the composition of such characters can sometimes seem arbitrary today.

A:
strokes
