Problem: Please answer a question about the following article about Zinc:
Several dozen radioisotopes have been characterized. 65Zn, which has a half-life of 243.66 days, is the most long-lived radioisotope, followed by 72Zn with a half-life of 46.5 hours. Zinc has 10 nuclear isomers. 69mZn has the longest half-life, 13.76 h. The superscript m indicates a metastable isotope. The nucleus of a metastable isotope is in an excited state and will return to the ground state by emitting a photon in the form of a gamma ray. 61Zn has three excited states and 73Zn has two. The isotopes 65Zn, 71Zn, 77Zn and 78Zn each have only one excited state.
What does a metastable isotope do to return to ground state from an excited state?
A: emitting a photon in the form of a gamma ray
Problem: Please answer a question about the following article about Phonology:
An important part of traditional, pre-generative schools of phonology is studying which sounds can be grouped into distinctive units within a language; these units are known as phonemes. For example, in English, the "p" sound in pot is aspirated (pronounced [p]) while that in spot is not aspirated (pronounced [p]). However, English speakers intuitively treat both sounds as variations (allophones) of the same phonological category, that is of the phoneme /p/. (Traditionally, it would be argued that if an aspirated [p] were interchanged with the unaspirated [p] in spot, native speakers of English would still hear the same words; that is, the two sounds are perceived as "the same" /p/.) In some other languages, however, these two sounds are perceived as different, and they are consequently assigned to different phonemes. For example, in Thai, Hindi, and Quechua, there are minimal pairs of words for which aspiration is the only contrasting feature (two words can have different meanings but with the only difference in pronunciation being that one has an aspirated sound where the other has an unaspirated one).
What is the opposite of aspirated?
A: unaspirated
Problem: Please answer a question about the following article about History of India:
As a result of the three Carnatic Wars, the British East India Company gained exclusive control over the entire Carnatic region of India. The Company soon expanded its territories around its bases in Bombay and Madras; the Anglo-Mysore Wars (17661799) and later the Anglo-Maratha Wars (17721818) led to control of the vast regions of India. Ahom Kingdom of North-east India first fell to Burmese invasion and then to British after Treaty of Yandabo in 1826. Punjab, North-West Frontier Province, and Kashmir were annexed after the Second Anglo-Sikh War in 1849; however, Kashmir was immediately sold under the Treaty of Amritsar to the Dogra Dynasty of Jammu and thereby became a princely state. The border dispute between Nepal and British India, which sharpened after 1801, had caused the Anglo-Nepalese War of 181416 and brought the defeated Gurkhas under British influence. In 1854, Berar was annexed, and the state of Oudh was added two years later.
After the sale of Kashmir, what did the area become?
A: princely state
Problem: Please answer a question about the following article about Association football:
Association football is played in accordance with a set of rules known as the Laws of the Game. The game is played using a spherical ball of 68.569.5 cm (27.027.4 in) circumference, known as the football (or soccer ball). Two teams of eleven players each compete to get the ball into the other team's goal (between the posts and under the bar), thereby scoring a goal. The team that has scored more goals at the end of the game is the winner; if both teams have scored an equal number of goals then the game is a draw. Each team is led by a captain who has only one official responsibility as mandated by the Laws of the Game: to be involved in the coin toss prior to kick-off or penalty kicks.
How many players are on each team?
A:
eleven
