Problem: Please answer a question about the following article about Circadian rhythm:
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 (clock19) 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.
What gene did Konopka and Benzer map in the early 1970 s?
A: "period"
Problem: Please answer a question about the following article about Apollo:
Daphne was a nymph, daughter of the river god Peneus, who had scorned Apollo. The myth explains the connection of Apollo with (daphne), the laurel whose leaves his priestess employed at Delphi. In Ovid's Metamorphoses, Phoebus Apollo chaffs Cupid for toying with a weapon more suited to a man, whereupon Cupid wounds him with a golden dart; simultaneously, however, Cupid shoots a leaden arrow into Daphne, causing her to be repulsed by Apollo. Following a spirited chase by Apollo, Daphne prays to her father, Peneus, for help, and he changes her into the laurel tree, sacred to Apollo.
Who is Daphne's father?
A: Peneus
Problem: Please answer a question about the following article about Bird migration:
Bird migration is primarily, but not entirely, a Northern Hemisphere phenomenon. This is because land birds in high northern latitudes, where food becomes scarce in winter, leave for areas further south (including the Southern Hemisphere) to overwinter, and because the continental landmass is much larger in the Northern Hemisphere. In contrast, among (pelagic) seabirds, species of the Southern Hemisphere are more likely to migrate. This is because there is a large area of ocean in the Southern Hemisphere, and more islands suitable for seabirds to nest.
In which hemisphere does bird migration primarily happen?
A:
Northern
