i - ready determine word meanings using known words and suffixes - er/or and - ness — instruction — level c complete the sentence. tristan didnt mind doing chores with his uncle, because uncle jays made everything more fun. usefulness runner playfulness gardener tried hard in the great cho would win the scrubbing g weeding contest this time?

Explanation:

The -ness suffix forms a noun denoting a state or quality. "Usefulness" means the quality of being useful and "playfulness" means the quality of being playful. Since the context is about making things more fun, "playfulness" fits better as it relates to a fun - like quality. The -er/or suffix forms a noun denoting a person who performs an action. "Runner" and "gardener" are people - not qualities.

Answer:

playfulness
