Al-Azhar University, founded in Cairo, Egypt in 975 by the Ismaili Shii Fatimid dynasty as a jamiah, had individual faculties for a theological seminary, Islamic law and jurisprudence, Arabic grammar, Islamic astronomy, early Islamic philosophy and logic in Islamic philosophy. The postgraduate doctorate in law was only obtained after "an oral examination to determine the originality of the candidate's theses", and to test the student's "ability to defend them against all objections, in disputations set up for the purpose." 'Abd al-Latif al-Baghdadi also delivered lectures on Islamic medicine at al-Azhar, while Maimonides delivered lectures on medicine and astronomy there during the time of Saladin. Another early jamiah was the Nizamiyah of Baghdad (founded 1091), which has been called the "largest university of the Medieval world." Mustansiriya University, established by the Abbasid caliph al-Mustansir in 1233, in addition to teaching the religious subjects, offered courses dealing with philosophy, mathematics and the natural sciences.

Input: Article: Chemical communications in animals rely on a variety of aspects including taste and smell. Chemoreception is the physiological response of a sense organ (i.e. taste or smell) to a chemical stimulus where the chemicals act as signals to regulate the state or activity of a cell. A semiochemical is a message-carrying chemical that is meant to attract, repel, and convey information. Types of semiochemicals include pheromones and kairomones. One example is the butterfly Phengaris arion which uses chemical signals as a form of mimicry to aid in predation.

Now answer this question: Chemical stimuli are signals that regulate the activity of what?

Output: a cell

Article: The algae are a polyphyletic group and are placed in various divisions, some more closely related to plants than others. There are many differences between them in features such as cell wall composition, biochemistry, pigmentation, chloroplast structure and nutrient reserves. The algal division Charophyta, sister to the green algal division Chlorophyta, is considered to contain the ancestor of true plants. The Charophyte class Charophyceae and the land plant sub-kingdom Embryophyta together form the monophyletic group or clade Streptophytina.

Question: Are all species of algae similar?
Ans: many differences

Here is a question about this article: The use of traditional Chinese characters versus simplified Chinese characters varies greatly, and can depend on both the local customs and the medium. Before the official reform, character simplifications were not officially sanctioned and generally adopted vulgar variants and idiosyncratic substitutions. Orthodox variants were mandatory in printed works, while the (unofficial) simplified characters would be used in everyday writing or quick notes. Since the 1950s, and especially with the publication of the 1964 list, the People's Republic of China has officially adopted simplified Chinese characters for use in mainland China, while Hong Kong, Macau, and the Republic of China (Taiwan) were not affected by the reform. There is no absolute rule for using either system, and often it is determined by what the target audience understands, as well as the upbringing of the writer.
What is the answer to this question: What were mandatory in printed works?
****
So... Orthodox variants

Following the 191415 edition, the competition was suspended due to the First World War, and didn't resume until 191920. The 192223 competition saw the first final to be played in the newly opened Wembley Stadium (known at the time as the Empire Stadium). Due to the outbreak of World War II, the competition wasn't played between the 193839 and 194546 editions. Due to the wartime breaks, the competition didn't celebrate its centenary year until 198081; fittingly the final featured a goal by Ricky Villa which was later voted the greatest goal ever scored at Wembley Stadium, but has since been replaced by Steven Gerrard.
When did Wembly stadium open?

The answer: 192223
