Answer 1

In novels, numbers are usually used to express a particular plot, character, or theme. The following are some common uses of numbers:

The number 1 is used to count or mark quantities. For example," he killed 10 enemies " or " she collected 100 gems."

The number 2 was used to represent time. For example," he went to New York in 1980 " or " she was trapped in the city in 2020 ".

The number 3 was used to represent space. For example," They must reach that location in 30 minutes " or " They have been tracked 400 miles away."

The number 4 is used to represent emotional or psychological states. For example," she felt 100% pain " or " he was 100% in a frenzy."

The number 5 is used to represent a special event or situation. For example, they were asked to complete the task in 10 minutes or they had to find the missing person but had no clues.

The use of numbers in a novel had to be chosen according to the plot and the needs of the characters in order to express the message the author wanted to convey.
