Question: In 1957, Braunstein further demonstrated that the rudimentary devices could be used for non-radio communication across a short distance. As noted by Kroemer Braunstein".. had set up a simple optical communications link: Music emerging from a record player was used via suitable electronics to modulate the forward current of a GaAs diode. The emitted light was detected by a PbS diode some distance away. This signal was fed into an audio amplifier, and played back by a loudspeaker. Intercepting the beam stopped the music. We had a great deal of fun playing with this setup." This setup presaged the use of LEDs for optical communication applications.
Try to answer this question if possible: Who discovered radio uses for early LED devices?
Answer: unanswerable
Question: BYU accepted 49 percent of the 11,423 people who applied for admission in the summer term and fall semester of 2013. The average GPA for these admitted students was 3.82.

Question: In the United States, there was a movement to resettle American free blacks and freed slaves in Africa. The American Colonization Society was founded in 1816 in Washington, DC for this purpose, by a group of prominent politicians and slaveholders. But its membership grew to include mostly people who supported abolition of slavery. Slaveholders wanted to get free people of color out of the South, where they were thought to threaten the stability of the slave societies. Some abolitionists collaborated on relocation of free blacks, as they were discouraged by discrimination against them in the North and believed they would never be accepted in the larger society. Most African Americans, who were native-born by this time, wanted to improve conditions in the United States rather than emigrate. Leading activists in the North strongly opposed the ACS, but some free blacks were ready to try a different environment.
Try to answer this question if possible: rather than emigrate African Americans wanted to do what?
Answer: improve conditions in the United States
Question: More importantly, the contests were open to all, and the enforced anonymity of each submission guaranteed that neither gender nor social rank would determine the judging. Indeed, although the "vast majority" of participants belonged to the wealthier strata of society ("the liberal arts, the clergy, the judiciary, and the medical profession"), there were some cases of the popular classes submitting essays, and even winning. Similarly, a significant number of women participated – and won – the competitions. Of a total of 2300 prize competitions offered in France, women won 49 – perhaps a small number by modern standards, but very significant in an age in which most women did not have any academic training. Indeed, the majority of the winning entries were for poetry competitions, a genre commonly stressed in women's education.
Try to answer this question if possible: Women's education common stressed which literary genre?
Answer:
poetry
