Which detail MOST clearly shows where the IAU got the idea to make a sign language dictionary for astronomical words? A) Over the last six years, members collected space-related signs from different sign languages. Earlier this month, the group announced a list of 47 common ones.
B) Each one is translated in up to 31 other sign languages. Portuguese, Russian and Finnish are among the languages.
C) The project was inspired by a French Sign Language (LSF) astronomy dictionary. The dictionary is called "Les mains dans les étoiles."
D) A few years later, the IAU created the group Astronomy for Inclusion and Equity. It aims to help people with special needs get information on astronomy.
