It should only take 7 to 10 days for your temporary certificate to become accessible if you have previously passed the Part 107 knowledge test and submitted an application for the remote pilot certificate via the IACRA website.
After it is granted, the temporary certificate is only good for 120 days. Your permanent certificate will be mailed to you during this period. The waiting period is much longer for this; most individuals report that it took them around two months to acquire their permanent certificates.

Answer:
Not a single person.
Explanation:
In the essay "I, Pencil" by Leonard E. Read, the author says that though about one and one-half billion pencils are produced in US alone each year, he says that not a single person in the whole earth knows how to actually make a pencil.
The author says that the economy of the country could never be systematically planned when not even a single person possesses the skills to even make a pencil. The writer uses the word 'pencil' to represent the most simplest tool yet how no one actually has the skills to make one in the country.
