She flew to Los Angeles last week, after her 74-year-old mother had a stroke, but is expected to return to Texas in a few days.
Her mother had been alive for more than 7 decades at that point.
She was 74 and 7 decades is only 70 years. It's difficult because perhaps the system thinks I mean 8 decades, so it marks the statement as incorrect.
