Article: In 1896, Patrick and Gilbert observed that during a prolonged period of sleep deprivation, sleepiness increases and decreases with a period of approximately 24 hours. In 1918, J.S. Szymanski showed that animals are capable of maintaining 24-hour activity patterns in the absence of external cues such as light and changes in temperature. In the early 20th century, circadian rhythms were noticed in the rhythmic feeding times of bees. Extensive experiments were done by Auguste Forel, Ingeborg Beling, and Oskar Wahl to see whether this rhythm was due to an endogenous clock.[citation needed] Ron Konopka and Seymour Benzer isolated the first clock mutant in Drosophila in the early 1970s and mapped the "period" gene, the first discovered genetic determinant of behavioral rhythmicity. Joseph Takahashi discovered the first mammalian circadian clock mutation (clockΔ19) using mice in 1994. However, recent studies show that deletion of clock does not lead to a behavioral phenotype (the animals still have normal circadian rhythms), which questions its importance in rhythm generation.

Question: What animals rhythmic feeding times were studied in the early 20th century ?
Ans: bees


Article: Carnival was introduced by Portuguese settlers. The celebration is celebrated on each of the archipelago's nine inhabited islands. In Mindelo, São Vicente groups challenge each other for a yearly prize. It has imported various Brazilian carnival traditions. The celebration in SãoNicolau is more traditional, where established groups parade through the Ribeira Brava, gathering in the town square, although it has adopted drums, floats and costumes from Brazil. In São Nicolau three groups, Copa Cabana, Estrela Azul and Brilho Da Zona constructs a painted float using fire, newspaper for the mold, iron and steel to for structure. Carnival São Nicolau is celebrated over three days: dawn Saturday, Sunday afternoon, and Tuesday.

Question: Over how many days is São Nicolau's Carnival celebrated? 
Ans: three


Article: Statehood for Alaska was an important cause of James Wickersham early in his tenure as a congressional delegate. Decades later, the statehood movement gained its first real momentum following a territorial referendum in 1946. The Alaska Statehood Committee and Alaska's Constitutional Convention would soon follow. Statehood supporters also found themselves fighting major battles against political foes, mostly in the U.S. Congress but also within Alaska. Statehood was approved by Congress on July 7, 1958. Alaska was officially proclaimed a state on January 3, 1959.

Question: On what day was Alaska officially named a state?
Ans: January 3, 1959


Article: MIME defines two different mechanisms for encoding non-ASCII characters in email, depending on whether the characters are in email headers (such as the "Subject:"), or in the text body of the message; in both cases, the original character set is identified as well as a transfer encoding. For email transmission of Unicode the UTF-8 character set and the Base64 or the Quoted-printable transfer encoding are recommended, depending on whether much of the message consists of ASCII-characters. The details of the two different mechanisms are specified in the MIME standards and generally are hidden from users of email software.

Question: How many different mechanisms does MIME define for encoding Unicode in email? 
Ans:
two different mechanisms
