Article: Men's rhythmic gymnastics is related to both Men's artistic gymnastics and wushu martial arts. It emerged in Japan from stick gymnastics. Stick gymnastics has been taught and performed for many years with the aim of improving physical strength and health. Male athletes are judged on some of the same physical abilities and skills as their female counterparts, such as hand/body-eye co-ordination, but tumbling, strength, power, and martial arts skills are the main focus, as opposed to flexibility and dance in women's rhythmic gymnastics. There are a growing number of participants, competing alone and on a team; it is most popular in Asia, especially in Japan where high school and university teams compete fiercely. As of 2002[update], there were 1000 men's rhythmic gymnasts in Japan.[citation needed]

Question: What are mens' rhythmic gymnastics related to?
Ans: both Men's artistic gymnastics and wushu martial arts

Here is a question about this article: In a nationally televised speech early in the morning of December 25, 1991, Gorbachev resigned as president of the USSR or, as he put it, "I hereby discontinue my activities at the post of President of the Union of Soviet Socialist Republics." He declared the office extinct, and all of its powers (such as control of the nuclear arsenal) were ceded to Yeltsin. A week earlier, Gorbachev had met with Yeltsin and accepted the fait accompli of the Soviet Union's dissolution. On the same day, the Supreme Soviet of the Russian SFSR adopted a statute to change Russia's legal name from "Russian Soviet Federative Socialist Republic" to "Russian Federation," showing that it was now a sovereign state.
What is the answer to this question: When did Gorbachev resign?
****
So... December 25, 1991

The problem: Answer a question about this article:
Temporal theories offer an alternative that appeals to the temporal structure of action potentials, mostly the phase-locking and mode-locking of action potentials to frequencies in a stimulus. The precise way this temporal structure helps code for pitch at higher levels is still debated, but the processing seems to be based on an autocorrelation of action potentials in the auditory nerve. However, it has long been noted that a neural mechanism that may accomplish a delaya necessary operation of a true autocorrelationhas not been found. At least one model shows that a temporal delay is unnecessary to produce an autocorrelation model of pitch perception, appealing to phase shifts between cochlear filters; however, earlier work has shown that certain sounds with a prominent peak in their autocorrelation function do not elicit a corresponding pitch percept, and that certain sounds without a peak in their autocorrelation function nevertheless elicit a pitch. To be a more complete model, autocorrelation must therefore apply to signals that represent the output of the cochlea, as via auditory-nerve interspike-interval histograms. Some theories of pitch perception hold that pitch has inherent octave ambiguities, and therefore is best decomposed into a pitch chroma, a periodic value around the octave, like the note names in western musicand a pitch height, which may be ambiguous, that indicates the octave the pitch is in.
Is a temporal delay necessary to produce an autocorrelation model of pitch perception?
****
The answer: unnecessary

Problem: Please answer a question about the following article about Ashkenazi Jews:
New developments in Judaism often transcend differences in religious practice between Ashkenazi and Sephardic Jews. In North American cities, social trends such as the chavurah movement, and the emergence of "post-denominational Judaism" often bring together younger Jews of diverse ethnic backgrounds. In recent years, there has been increased interest in Kabbalah, which many Ashkenazi Jews study outside of the Yeshiva framework. Another trend is the new popularity of ecstatic worship in the Jewish Renewal movement and the Carlebach style minyan, both of which are nominally of Ashkenazi origin.
What two things were mentioned as contributing to bringing younger Jews together in North American cities?
A: social trends such as the chavurah movement, and the emergence of "post-denominational Judaism"

On 23 February, the 28th Marine Regiment reached the summit of Suribachi, prompting the now famous Raising the Flag on Iwo Jima picture. Navy Secretary James Forrestal, upon seeing the flag, remarked "there will be a Marine Corps for the next 500 years." The flag raising is often cited as the most reproduced photograph of all time and became the archetypal representation not only of that battle, but of the entire Pacific War. For the rest of February, the Americans pushed north, and by 1 March, had taken two-thirds of the island. But it was not until 26 March that the island was finally secured. The Japanese fought to the last man, killing 6,800 Marines and wounding nearly 20,000 more. The Japanese losses totaled well over 20,000 men killed, and only 1,083 prisoners were taken. Historians debate whether it was strategically worth the casualties sustained.

When was the island of Iwo Jima secured by the Americans?
Answer: 26 March

Unlike other Germanic languages, Dutch doesn't have phonological aspiration of consonants. Like English, Dutch did not participate in the second consonant shift. Like most Germanic languages, the Dutch consonant system did not undergo the High German consonant shift and has a syllable structure that allows fairly complex consonant clusters. Dutch also retains full use of the velar fricatives that were present in Proto-Germanic, but lost or modified in many other Germanic languages. Dutch has final-obstruent devoicing: at the end of a word, voicing distinction is neutralised and all obstruents are pronounced voiceless. For example, goede ("good") is /ud/ but the related form goed is /ut/. Dutch shares with German Final-obstruent devoicing (Du brood [brot] and German Brot vs Eng bread).
What sound does Dutch still use from Proto-Germanic that was phased out in other Germanic languages?
velar fricatives
