Suppose Tina has missed the last three meetings at work due to a family emergency. Her boss, Sarah, has been understanding and supportive during this difficult time. However, Tina's colleague, Karen, has started spreading rumors that Tina is unreliable and not committed to her job. Sarah has not addressed these rumors directly with Karen yet.
Can we infer that "Sarah is not aware of the rumors being spread by Karen about Tina's attendance at work"?
