41. In Roman times, a balance scale (libra) was used for weighing. It had a balance arm from which two scale pans were suspended at equal distances from the point of suspension. The goods to be weighed were placed on one scale pan, and pre-measured weights of lead, stone, bronze, or iron were placed on the other pan until the two pans balanced.

What are the fewest pre-measured weights that would be needed to measure any exact number of ounces from 1 to 120?

Based on the following information, match the names of six tenants with their occupations and the locations of their shops on the floor plan of the insula shown on the right.

  • Every other shop is run by a woman, but one shop is vacant.

    · to denote numbers being used as adverbs ().
