Input: Article: Cotton is used to make a number of textile products. These include terrycloth for highly absorbent bath towels and robes; denim for blue jeans; cambric, popularly used in the manufacture of blue work shirts (from which we get the term "blue-collar"); and corduroy, seersucker, and cotton twill. Socks, underwear, and most T-shirts are made from cotton. Bed sheets often are made from cotton. Cotton also is used to make yarn used in crochet and knitting. Fabric also can be made from recycled or recovered cotton that otherwise would be thrown away during the spinning, weaving, or cutting process. While many fabrics are made completely of cotton, some materials blend cotton with other fibers, including rayon and synthetic fibers such as polyester. It can either be used in knitted or woven fabrics, as it can be blended with elastine to make a stretchier thread for knitted fabrics, and apparel such as stretch jeans.

Now answer this question: For what can cotton yarn be used?

Output: crochet and knitting


Article: 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

Question: How are stage lifts powered?
Ans: by hydraulics

Next to sound shifts, there are ample examples of suffix differences. Often simple suffix shifts (like switching between -the, -ske, -ke, -je, ...), sometimes the suffixes even depend on quite specific grammar rules for a certain dialect. Again taking West Flemish as an example. In that language, the words "ja" (yes) and "nee" (no) are also conjugated to the (often implicit) subject of the sentence. These separate grammar rules are a lot more difficult to imitate correctly than simple sound shifts, making it easy to recognise people who didn't grow up in a certain region, even decades after they moved.

How would you tell a West Flemish speaker "yes"?
Answer:
ja
