Question

which is the best way to complete the text? ancient mathematicians probably used symbols to represent the \empty columns,\ or zeros, in a number such as ______ the concept of zero as a number wasnt developed until the fifth century ce. 100, or 100; however, 100, yet, 100, however,

Explanation:

The text shows a contrast: ancient mathematicians used symbols for empty columns (like in 100) but the full concept of zero as a number came much later. We need a punctuation and conjunction that correctly sets up this contrast. A colon after 100 properly introduces the example, and "however" clearly signals the opposing idea. The other options use incorrect punctuation (commas instead of colons for the example) or redundant/incorrect conjunctions.

Answer:

100; however,
