In response, Shell filed lawsuits to seek injunctions from possible protests, and Benjamin Jealous of the NAACP and Radford argued that the legal action was "trampling American's rights." According to Greenpeace, Shell lodged a request with Google to ban video footage of a Greenpeace protest action that occurred at the Shell-sponsored Formula One (F1) Belgian Grand Prix on 25 August 2013, in which "SaveTheArctic.org" banners appear at the winners' podium ceremony. In the video, the banners rise up automatically—activists controlled their appearance with the use of four radio car antennas—revealing the website URL, alongside an image that consists of half of a polar bear's head and half of the Shell logo.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): At the 2013 ceremony, activitsts controlled their appearance with what?
Ah, so.. the use of four radio car antennas

Yale has a history of difficult and prolonged labor negotiations, often culminating in strikes. There have been at least eight strikes since 1968, and The New York Times wrote that Yale has a reputation as having the worst record of labor tension of any university in the U.S. Yale's unusually large endowment exacerbates the tension over wages. Moreover, Yale has been accused of failing to treat workers with respect. In a 2003 strike, however, the university claimed that more union employees were working than striking. Professor David Graeber was 'retired' after he came to the defense of a student who was involved in campus labor issues.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How many strikes has Yale had since 1968?
Ah, so.. at least eight

The oldest known archaeological fragments of the immediate precursor to modern paper, date to the 2nd century BC in China. The pulp papermaking process is ascribed to Cai Lun, a 2nd-century AD Han court eunuch. With paper as an effective substitute for silk in many applications, China could export silk in greater quantity, contributing to a Golden Age.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): To whom is the silk paper making process ascribed?
Ah, so..
unanswerable
