Problem: Gymnastics:

The technical rules for the Japanese version of men's rhythmic gymnastics came around the 1970s. For individuals, only four types of apparatus are used: the double rings, the stick, the rope, and the clubs. Groups do not use any apparatus. The Japanese version includes tumbling performed on a spring floor. Points are awarded based a 10-point scale that measures the level of difficulty of the tumbling and apparatus handling. On November 2729, 2003, Japan hosted first edition of the Men's Rhythmic Gymnastics World Championship.

How many apparatuses are used?
---
A: only four types

Problem: As part of this Popular Revolution, Gaddafi invited Libya's people to found General People's Committees as conduits for raising political consciousness. Although offering little guidance for how to set up these councils, Gaddafi claimed that they would offer a form of direct political participation that was more democratic than a traditional party-based representative system. He hoped that the councils would mobilize the people behind the RCC, erode the power of the traditional leaders and the bureaucracy, and allow for a new legal system chosen by the people.
Along with the bureaucracy, who were the General People's Committees directed at?
---
Answer: traditional leaders

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Equivalently, the smallness of the Planck constant reflects the fact that everyday objects and systems are made of a large number of particles. For example, green light with a wavelength of 555 nanometres (the approximate wavelength to which human eyes are most sensitive) has a frequency of 7014540000000000000♠️540 THz (7014540000000000000♠️5401012 Hz). Each photon has an energy E = hf = 6981358000000000000♠️3.581019 J. That is a very small amount of energy in terms of everyday experience, but everyday experience is not concerned with individual photons any more than with individual atoms or molecules. An amount of light compatible with everyday experience is the energy of one mole of photons; its energy can be computed by multiplying the photon energy by the Avogadro constant, NA 7023602200000000000♠️6.0221023 mol1. The result is that green light of wavelength 555 nm has an energy of 7005216000000000000♠️216 kJ/mol, a typical energy of everyday life.
What is the frequency of the light to which the human eye is most sensitive?
A: 7014540000000000000♠️540 THz

Context and question: The central Sahara is estimated to include five hundred species of plants, which is extremely low considering the huge extent of the area. Plants such as acacia trees, palms, succulents, spiny shrubs, and grasses have adapted to the arid conditions, by growing lower to avoid water loss by strong winds, by storing water in their thick stems to use it in dry periods, by having long roots that travel horizontally to reach the maximum area of water and to find any surface moisture and by having small thick leaves or needles to prevent water loss by evapo-transpiration. Plant leaves may dry out totally and then recover.
Where do plants store their water to avoid the conditions?
Answer: thick stems

Question: In Japan, 14 August is considered to be the day that the Pacific War ended. However, as Imperial Japan actually surrendered on 15 August, this day became known in the English-speaking countries as "V-J Day" (Victory in Japan). The formal Japanese Instrument of Surrender was signed on 2 September 1945, on the battleship USS Missouri, in Tokyo Bay. The surrender was accepted by General Douglas MacArthur as Supreme Commander for the Allied Powers, with representatives of several Allied nations, from a Japanese delegation led by Mamoru Shigemitsu and Yoshijiro Umezu.
Is there an answer to this question: What day is know in the United States as "V-J Day"?

Answer: 15 August

Victoria was physically unprepossessingshe was stout, dowdy and no more than five feet tallbut she succeeded in projecting a grand image. She experienced unpopularity during the first years of her widowhood, but was well liked during the 1880s and 1890s, when she embodied the empire as a benevolent matriarchal figure. Only after the release of her diary and letters did the extent of her political influence become known to the wider public. Biographies of Victoria written before much of the primary material became available, such as Lytton Strachey's Queen Victoria of 1921, are now considered out of date. The biographies written by Elizabeth Longford and Cecil Woodham-Smith, in 1964 and 1972 respectively, are still widely admired. They, and others, conclude that as a person Victoria was emotional, obstinate, honest, and straight-talking.
What kind of person was Victoria?
A:
emotional, obstinate, honest, and straight-talking
