Q: story: An incandescent light bulb, incandescent lamp or incandescent light globe is an electric light with a wire filament heated to a high temperature, by passing an electric current through it, until it glows with visible light (incandescence). The hot filament is protected from oxidation with a glass or quartz bulb that is filled with inert gas or evacuated. In a halogen lamp, filament evaporation is prevented by a chemical process that redeposits metal vapor onto the filament, extending its life. The light bulb is supplied with electric current by feed-through terminals or wires embedded in the glass. Most bulbs are used in a socket which provides mechanical support and electrical connections. 

Incandescent bulbs are much less efficient than most other types of electric lighting; incandescent bulbs convert less than 5% of the energy they use into visible light, with standard light bulbs averaging about 2.2%. The remaining energy is converted into heat. The luminous efficacy of a typical incandescent bulb is 16 lumens per watt, compared with 60 lm/W for a compact fluorescent bulb or 150 lm/W for some white LED lamps. Some applications of the incandescent bulb deliberately use the heat generated by the filament. Such applications include incubators, brooding boxes for poultry, heat lights for reptile tanks, infrared heating for industrial heating and drying processes, lava lamps, and the Easy-Bake Oven toy. Incandescent bulbs typically have short lifetimes compared with other types of lighting; around 1,000 hours for home light bulbs versus typically 10,000 hours for compact fluorescents and 30,000 hours for lighting LEDs., question: How about in a halogen bulb?

A: a chemical process

Q: story: (CNN) -- Jason Priestley played Brandon Walsh on "Beverly Hills 90210" from 1990 to 1998. Having long since hung up his Peach Pit uniform and Beverly Hills Beach Club cabana boy polo shirt, his character became a journalist and departed to take a job at the Washington Bureau of the New York Chronicle, and Priestley left the show four episodes into the series' ninth season. 

"I felt that the character of Brandon had kind of run his course. I had explored everything I wanted to explore with him," Priestley told CNN while promoting his new book, "Jason Priestley: A Memoir" (HarperOne) at the New York Bureau of CNN. 

"In retrospect, I do regret leaving. Understanding what I do now about story and character, I believe that [Aaron Spelling] was pushing the story in a direction that would have had Brandon and Kelly end up together at the end of the show and I think I probably should have stuck around to its fruition." 

Fans of "90210" surely remember Kelly Taylor's (Jennie Garth) "I choose me" speech following Brandon and Dylan McKay's (Luke Perry) showdown for her affections. Brandon wanted Kelly to marry him. Dylan wanted to take her on a trip around the world. But Priestley believes Executive Producer Aaron Spelling had always envisioned Brandon and Kelly riding off into the sunset. 

"I think my departure also hurt Aaron's feelings," continued Priestley. "Aaron and I had worked very closely together for a number of years. He gave me a lot of opportunities, and I feel like my departure hurt his feelings and I never meant to do that." , question: What did the other one want her to do with him?

A: he wanted to take her on a trip around the world.

Q: story: CHAPTER VII. THE DAUGHTER OF WITHERSTEEN 

"Lassiter, will you be my rider?" Jane had asked him. 

"I reckon so," he had replied. 

Few as the words were, Jane knew how infinitely much they implied. She wanted him to take charge of her cattle and horse and ranges, and save them if that were possible. Yet, though she could not have spoken aloud all she meant, she was perfectly honest with herself. Whatever the price to be paid, she must keep Lassiter close to her; she must shield from him the man who had led Milly Erne to Cottonwoods. In her fear she so controlled her mind that she did not whisper this Mormon's name to her own soul, she did not even think it. Besides, beyond this thing she regarded as a sacred obligation thrust upon her, was the need of a helper, of a friend, of a champion in this critical time. If she could rule this gun-man, as Venters had called him, if she could even keep him from shedding blood, what strategy to play his flame and his presence against the game of oppression her churchmen were waging against her? Never would she forget the effect on Tull and his men when Venters shouted Lassiter's name. If she could not wholly control Lassiter, then what she could do might put off the fatal day. 

One of her safe racers was a dark bay, and she called him Bells because of the way he struck his iron shoes on the stones. When Jerd led out this slender, beautifully built horse Lassiter suddenly became all eyes. A rider's love of a thoroughbred shone in them. Round and round Bells he walked, plainly weakening all the time in his determination not to take one of Jane's favorite racers. , question: How did he get his name?

A:
because of the way he struck his iron shoes on the stones.
