Final answer:
Based on available data from 2015, it can be inferred that 57 percent of adults did not read a single novel in that year. There is no specific percentage available for the past year without more current statistics.
Step-by-step explanation:
The question "What percentage of people did not read a single novel in the past year?" aims to determine the proportion of the population that did not engage in a specific literary activity. In the context of the information provided, the closest data point we have is from 2015, where it was reported that 43 percent of adults read at least one work of literature in the previous year.
Assuming that this statistic encompasses novels and that the remaining population did not read any literature, including novels, we can infer that 57 percent of adults did not read a single novel in that year. However, without data specifically on novel-reading patterns more recent than that year, it is not possible to give an exact percentage for the past year without further research or updated statistics.
