Answer:
The streets are unusually crowded
Explanation:
In line 2 it says "Mother Lois maneuvered through the unsually heavy traffic."
And then again in line 3 it says "'I don't know how where all the cars could have come from,'"
Both of these lines mention that the street is very crowded.
The streets are unusually crowded.
From the text we understand that the traffic is unusually heavy and that there had never been so many people driving in the quiet neighbourhood.
