A noun is a person, place, or thing
I think A would be your best bet but im not 100% sure, space is a place and everyone I guess would be considered a person/people
It is a because it’s going against what the first sentence was saying hope it helps!
If it is from the passage Doctor Pascal by Emile Zola, it is Dawnlike.
Jewish ghettos in Europe were neighbourhoods of European cities in which Jews were permitted to live. In addition to being confined to the ghettos, Jews were placed under strict regulations as well as restrictions in many European cities.[1] The character of ghettos fluctuated over the centuries. In some cases, they comprised a Jewish quarter, the area of a city traditionally inhabited by Jews. In many instances, ghettos were places of terrible poverty and during periods of population growth, ghettos had narrow streets and small, crowded houses. Residents had their own justice system. Around the ghetto stood walls that, during pogroms, were closed from inside to protect the community, but from the outside during Christmas, Pesach, and Easter Week to prevent the Jews from leaving at those times.
