Problem: For temperature studies, subjects must remain awake but calm and semi-reclined in near darkness while their rectal temperatures are taken continuously. Though variation is great among normal chronotypes, the average human adult's temperature reaches its minimum at about 05:00 (5 a.m.), about two hours before habitual wake time. Baehr et al. found that, in young adults, the daily body temperature minimum occurred at about 04:00 (4 a.m.) for morning types but at about 06:00 (6 a.m.) for evening types. This minimum occurred at approximately the middle of the eight hour sleep period for morning types, but closer to waking in evening types.
What physical factor must be continuously monitored during temperature studies> 
The answer is the following: temperatures

Problem: From 1842 onwards, Chopin showed signs of serious illness. After a solo recital in Paris on 21 February 1842, he wrote to Grzymała: "I have to lie in bed all day long, my mouth and tonsils are aching so much." He was forced by illness to decline a written invitation from Alkan to participate in a repeat performance of the Beethoven Seventh Symphony arrangement at Erard's on 1 March 1843. Late in 1844, Charles Hallé visited Chopin and found him "hardly able to move, bent like a half-opened penknife and evidently in great pain", although his spirits returned when he started to play the piano for his visitor. Chopin's health continued to deteriorate, particularly from this time onwards. Modern research suggests that apart from any other illnesses, he may also have suffered from temporal lobe epilepsy.
To whom did Chopin write a letter on 21 February 1842 about his agonizing pain?
The answer is the following: Grzymała

Problem: In the U.S., a push for revisions of the FD&C Act emerged from Congressional hearings led by Senator Estes Kefauver of Tennessee in 1959. The hearings covered a wide range of policy issues, including advertising abuses, questionable efficacy of drugs, and the need for greater regulation of the industry. While momentum for new legislation temporarily flagged under extended debate, a new tragedy emerged that underscored the need for more comprehensive regulation and provided the driving force for the passage of new laws.
When did this push occur?
The answer is the following:
1959
