question:
Passage: Translations of sung texts—whether of the above type meant to be sung or of a more or less literal type meant to be read—are also used as aids to audiences, singers and conductors, when a work is being sung in a language not known to them. The most familiar types are translations presented as subtitles or surtitles projected during opera performances, those inserted into concert programs, and those that accompany commercial audio CDs of vocal music. In addition, professional and amateur singers often sing works in languages they do not know (or do not know well), and translations are then used to enable them to understand the meaning of the words they are singing.
answer:
Who can translations of a sung text harm?


question:
Passage: Extension causes the rock units as a whole to become longer and thinner. This is primarily accomplished through normal faulting and through the ductile stretching and thinning. Normal faults drop rock units that are higher below those that are lower. This typically results in younger units being placed below older units. Stretching of units can result in their thinning; in fact, there is a location within the Maria Fold and Thrust Belt in which the entire sedimentary sequence of the Grand Canyon can be seen over a length of less than a meter. Rocks at the depth to be ductilely stretched are often also metamorphosed. These stretched rocks can also pinch into lenses, known as boudins, after the French word for "sausage", because of their visual similarity.
answer:
What is another word for thinning rocks in French?

Passage: Since the mid-1980s, Spielberg has increased his role as a film producer. He headed up the production team for several cartoons, including the Warner Bros. hits Tiny Toon Adventures, Animaniacs, Pinky and the Brain, Toonsylvania, and Freakazoid!, for which he collaborated with Jean MacCurdy and Tom Ruegger. Due to his work on these series, in the official titles, most of them say, "Steven Spielberg presents" as well as making numerous cameos on the shows. Spielberg also produced the Don Bluth animated features, An American Tail and The Land Before Time, which were released by Universal Studios. He also served as one of the executive producers of Who Framed Roger Rabbit and its three related shorts (Tummy Trouble, Roller Coaster Rabbit, Trail Mix-Up), which were all released by Disney, under both the Walt Disney Pictures and the Touchstone Pictures banners. He was furthermore, for a short time, the executive producer of the long-running medical drama ER. In 1989, he brought the concept of The Dig to LucasArts. He contributed to the project from that time until 1995 when the game was released. He also collaborated with software publishers Knowledge Adventure on the multimedia game Steven Spielberg's Director's Chair, which was released in 1996. Spielberg appears, as himself, in the game to direct the player. The Spielberg name provided branding for a Lego Moviemaker kit, the proceeds of which went to the Starbright Foundation.
