How many balls originally made up an over in Test cricket?
Correct!
When Test cricket began in 1877, an over consisted of four balls. The number changed several times later and at times even differed from country to country. Today, a regular over in international cricket consists of six valid balls. These historical differences are what make the question interesting: five, six, or eight balls per over were also used in different periods.
