Problem: Please answer a question about the following article about Light-emitting diode:
Digital-RGB LEDs are RGB LEDs that contain their own "smart" control electronics. In addition to power and ground, these provide connections for data-in, data-out, and sometimes a clock or strobe signal. These are connected in a daisy chain, with the data in of the first LED sourced by a microprocessor, which can control the brightness and color of each LED independently of the others. They are used where a combination of maximum control and minimum visible electronics are needed such as strings for Christmas and LED matrices. Some even have refresh rates in the kHz range, allowing for basic video applications.
What makes RGB LEDs different?
A: contain their own "smart" control electronics
Problem: Please answer a question about the following article about Quran:
According to the traditional narrative, several companions of Muhammad served as scribes and were responsible for writing down the revelations. Shortly after Muhammad's death, the Quran was compiled by his companions who wrote down and memorized parts of it. These codices had differences that motivated the Caliph Uthman to establish a standard version now known as Uthman's codex, which is generally considered the archetype of the Quran known today. There are, however, variant readings, with mostly minor differences in meaning.
Who first standardized the earliest versions of the Quran?
A: Caliph Uthman
Problem: Please answer a question about the following article about Bacteria:
Each species of pathogen has a characteristic spectrum of interactions with its human hosts. Some organisms, such as Staphylococcus or Streptococcus, can cause skin infections, pneumonia, meningitis and even overwhelming sepsis, a systemic inflammatory response producing shock, massive vasodilation and death. Yet these organisms are also part of the normal human flora and usually exist on the skin or in the nose without causing any disease at all. Other organisms invariably cause disease in humans, such as the Rickettsia, which are obligate intracellular parasites able to grow and reproduce only within the cells of other organisms. One species of Rickettsia causes typhus, while another causes Rocky Mountain spotted fever. Chlamydia, another phylum of obligate intracellular parasites, contains species that can cause pneumonia, or urinary tract infection and may be involved in coronary heart disease. Finally, some species, such as Pseudomonas aeruginosa, Burkholderia cenocepacia, and Mycobacterium avium, are opportunistic pathogens and cause disease mainly in people suffering from immunosuppression or cystic fibrosis.
Can all bacteria in human body be harmful?
A: exist on the skin or in the nose without causing any disease
Problem: Please answer a question about the following article about Buddhism:
According to author Michael Carrithers, while there are good reasons to doubt the traditional account, "the outline of the life must be true: birth, maturity, renunciation, search, awakening and liberation, teaching, death." In writing her biography of the Buddha, Karen Armstrong noted, "It is obviously difficult, therefore, to write a biography of the Buddha that meets modern criteria, because we have very little information that can be considered historically sound... [but] we can be reasonably confident Siddhatta Gotama did indeed exist and that his disciples preserved the memory of his life and teachings as well as they could."[dubious discuss]
What are the helpers called that helped Buddha?
A:
disciples
