Article: Because of their long life, fast switching times, and their ability to be seen in broad daylight due to their high output and focus, LEDs have been used in brake lights for cars' high-mounted brake lights, trucks, and buses, and in turn signals for some time, but many vehicles now use LEDs for their rear light clusters. The use in brakes improves safety, due to a great reduction in the time needed to light fully, or faster rise time, up to 0.5 second faster[citation needed] than an incandescent bulb. This gives drivers behind more time to react. In a dual intensity circuit (rear markers and brakes) if the LEDs are not pulsed at a fast enough frequency, they can create a phantom array, where ghost images of the LED will appear if the eyes quickly scan across the array. White LED headlamps are starting to be used. Using LEDs has styling advantages because LEDs can form much thinner lights than incandescent lamps with parabolic reflectors.

Question: Why are LED lights sought after for various applications?
Ans: their long life

Here is a question about this article: All modern birds lie within the crown group Aves (alternately Neornithes), which has two subdivisions: the Palaeognathae, which includes the flightless ratites (such as the ostriches) and the weak-flying tinamous, and the extremely diverse Neognathae, containing all other birds. These two subdivisions are often given the rank of superorder, although Livezey and Zusi assigned them "cohort" rank. Depending on the taxonomic viewpoint, the number of known living bird species varies anywhere from 9,800 to 10,050.
What is the answer to this question: All modern birds lie within which crown group?
****
So... Aves

Genre fiction also showed it could question reality in its 20th century forms, in spite of its fixed formulas, through the enquiries of the skeptical detective and the alternative realities of science fiction. The separation of "mainstream" and "genre" forms (including journalism) continued to blur during the period up to our own times. William Burroughs, in his early works, and Hunter S. Thompson expanded documentary reporting into strong subjective statements after the second World War, and post-modern critics have disparaged the idea of objective realism in general.
Alternative reality genre fiction is also known as what?
science fiction
