Input: Read this: In China, which uses simplified Chinese characters, the Xiàndài Hànyǔ Chángyòng Zìbiǎo (现代汉语常用字表, Chart of Common Characters of Modern Chinese) lists 2,500 common characters and 1,000 less-than-common characters, while the Xiàndài Hànyǔ Tōngyòng Zìbiǎo (现代汉语通用字表, Chart of Generally Utilized Characters of Modern Chinese) lists 7,000 characters, including the 3,500 characters already listed above. GB2312, an early version of the national encoding standard used in the People's Republic of China, has 6,763 code points. GB18030, the modern, mandatory standard, has a much higher number. The New Hànyǔ Shuǐpíng Kǎoshì (汉语水平考试, Chinese Proficiency Test) covers approximately 2,600 characters at its highest level (level six).
Question: What lists 2,500 common characters?

Output: Chart of Common Characters of Modern Chinese


QUES: Double fertilization refers to a process in which two sperm cells fertilize cells in the ovary. This process begins when a pollen grain adheres to the stigma of the pistil (female reproductive structure), germinates, and grows a long pollen tube. While this pollen tube is growing, a haploid generative cell travels down the tube behind the tube nucleus. The generative cell divides by mitosis to produce two haploid (n) sperm cells. As the pollen tube grows, it makes its way from the stigma, down the style and into the ovary. Here the pollen tube reaches the micropyle of the ovule and digests its way into one of the synergids, releasing its contents (which include the sperm cells). The synergid that the cells were released into degenerates and one sperm makes its way to fertilize the egg cell, producing a diploid (2n) zygote. The second sperm cell fuses with both central cell nuclei, producing a triploid (3n) cell. As the zygote develops into an embryo, the triploid cell develops into the endosperm, which serves as the embryo's food supply. The ovary now will develop into fruit and the ovule will develop into seed.

What process does double fertilization refer to?
What is the answer?
ANS: two sperm cells fertilize cells in the ovary


QUES: The language possesses five vowels (or six, under the St. Petersburg Phonological School), which are written with different letters depending on whether or not the preceding consonant is palatalized. The consonants typically come in plain vs. palatalized pairs, which are traditionally called hard and soft. (The hard consonants are often velarized, especially before front vowels, as in Irish). The standard language, based on the Moscow dialect, possesses heavy stress and moderate variation in pitch. Stressed vowels are somewhat lengthened, while unstressed vowels tend to be reduced to near-close vowels or an unclear schwa. (See also: vowel reduction in Russian.)
What pairs do vowels come in, in Irish?

ANS: unanswerable


The first visible-spectrum (red) LED was developed in 1962 by Nick Holonyak, Jr., while working at General Electric Company. Holonyak first reported his LED in the journal Applied Physics Letters on the December 1, 1962. M. George Craford, a former graduate student of Holonyak, invented the first yellow LED and improved the brightness of red and red-orange LEDs by a factor of ten in 1972. In 1976, T. P. Pearsall created the first high-brightness, high-efficiency LEDs for optical fiber telecommunications by inventing new semiconductor materials specifically adapted to optical fiber transmission wavelengths.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"):  What graduate student of Holonyak created the yellow non-LED?
Ah, so.. unanswerable


Question: A patent is a form of right granted by the government to an inventor, giving the owner the right to exclude others from making, using, selling, offering to sell, and importing an invention for a limited period of time, in exchange for the public disclosure of the invention. An invention is a solution to a specific technological problem, which may be a product or a process and generally has to fulfil three main requirements: it has to be new, not obvious and there needs to be an industrial applicability.:17
Try to answer this question if possible: Who grants a patent?
Answer: the government


Context and question: There is no easy way to determine when clothing was first developed, but some information has been inferred by studying lice. The body louse specifically lives in clothing, and diverge from head lice about 107,000 years ago, suggesting that clothing existed at that time. Another theory is that modern humans are the only survivors of several species of primates who may have worn clothes and that clothing may have been used as long ago as 650 thousand years ago. Other louse-based estimates put the introduction of clothing at around 42,000–72,000 BP.
What is easy to determine about clothing?
