Problem: Lighting:

Color temperature for white light sources also affects their use for certain applications. The color temperature of a white light source is the temperature in Kelvin of a theoretical black body emitter that most closely matches the spectral characteristics of the lamp. An incandescent bulb has a color temperature around 2800 to 3000 Kelvin; daylight is around 6400 Kelvin. Lower color temperature lamps have relatively more energy in the yellow and red part of the visible spectrum, while high color temperatures correspond to lamps with more of a blue-white appearance. For critical inspection or color matching tasks, or for retail displays of food and clothing, the color temperature of the lamps will be selected for the best overall lighting effect.

How many Kelvins is daylight measured at?
---
A: 6400

Problem: Differences in feasts may also originate from doctrinal issuesthe Feast of the Assumption is such an example. Given that there is no agreement among all Christians on the circumstances of the death, Dormition or Assumption of Mary, the feast of assumption is celebrated among some denominations and not others. While the Catholic Church celebrates the Feast of the Assumption on August 15, some Eastern Catholics celebrate it as Dormition of the Theotokos, and may do so on August 28, if they follow the Julian calendar. The Eastern Orthodox also celebrate it as the Dormition of the Theotokos, one of their 12 Great Feasts. Protestants do not celebrate this, or any other Marian feasts.
How many Great Feasts does the Eastern Orthodox Church celebrate?

Answer: 12

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Samurai were many of the early exchange students, not directly because they were samurai, but because many samurai were literate and well-educated scholars. Some of these exchange students started private schools for higher educations, while many samurai took pens instead of guns and became reporters and writers, setting up newspaper companies, and others entered governmental service. Some samurai became businessmen. For example, Iwasaki Yataro, who was the great-grandson of a samurai, established Mitsubishi.
Who did samurai write for?
A: newspaper companies

Context and question: Ali was assassinated in 661 by a Kharijite partisan. Six months later in the same year, in the interest of peace, Hasan ibn Ali, highly regarded for his wisdom and as a peacemaker, and the Second Imam for the Shias, and the grandson of Muhammad, made a peace treaty with Muawiyah I. In the Hasan-Muawiya treaty, Hasan ibn Ali handed over power to Muawiya on the condition that he be just to the people and keep them safe and secure, and after his death he not establish a dynasty. This brought to an end the era of the Rightly Guided Caliphs for the Sunnis, and Hasan ibn Ali was also the last Imam for the Shias to be a Caliph. Following this, Mu'awiyah broke the conditions of the agreement and began the Umayyad dynasty, with its capital in Damascus.
Who followed the conditions of the agreement?
Answer: unanswerable

Question: Adaptation of the endosymbiont to the host's lifestyle leads to many changes in the endosymbiontthe foremost being drastic reduction in its genome size. This is due to many genes being lost during the process of metabolism, and DNA repair and recombination. While important genes participating in the DNA to RNA transcription, protein translation and DNA/RNA replication are retained. That is, a decrease in genome size is due to loss of protein coding genes and not due to lessening of inter-genic regions or open reading frame (ORF) size. Thus, species that are naturally evolving and contain reduced sizes of genes can be accounted for an increased number of noticeable differences between them, thereby leading to changes in their evolutionary rates. As the endosymbiotic bacteria related with these insects are passed on to the offspring strictly via vertical genetic transmission, intracellular bacteria goes through many hurdles during the process, resulting in the decrease in effective population sizes when compared to the free living bacteria. This incapability of the endosymbiotic bacteria to reinstate its wild type phenotype via a recombination process is called as Muller's ratchet phenomenon. Muller's ratchet phenomenon together with less effective population sizes has led to an accretion of deleterious mutations in the non-essential genes of the intracellular bacteria. This could have been due to lack of selection mechanisms prevailing in the rich environment of the host.
Is there an answer to this question: What happens when the DNA/RNA replications are retained?

Answer: unanswerable

Problem: Professional wrestling:

The style of Japanese professional wrestling (puroresu) is again different. With its origins in traditional American style of wrestling and still being under the same genre, it has become an entity in itself. Despite the similarity to its American counterpart in that the outcome of the matches remains predetermined, the phenomena are different in the form of the psychology and presentation of the sport; it is treated as a full contact combat sport as it mixes hard hitting martial arts strikes with shoot style submission holds, while in the U.S. it is rather more regarded as an entertainment show. Wrestlers incorporate kicks and strikes from martial arts disciplines, and a strong emphasis is placed on submission wrestling, and unlike the use of involved storylines in the U.S., they are not as intricate in Japan, more emphasis is placed on the concept of Fighting Spirit, meaning the Wrestlers display of physical and mental stamina are valued a lot more than theatrics. Many of Japan's wrestlers including top stars such as Shinya Hashimoto, Riki Choshu and Keiji Mutoh came from a legitimate martial arts background and many Japanese wrestlers in the 1990s began to pursue careers in mixed martial arts organizations such as Pancrase and Shooto which at the time retained the original look of puroresu, but were actual competitions.

What does Japanese wrestling combine?

A:
hard hitting martial arts strikes with shoot style submission holds
