Suppose Sophie and Olivia are sisters who live in the same house with their parents, Lisa and Mark. Sophie is two years older than Olivia. Lisa is a doctor and Mark is a teacher. One day, Mark came home from work and found the kitchen in a mess. He asked the girls who made the mess, and Sophie immediately blamed Olivia for it. Olivia denied it, saying she was in her room the whole time studying. Lisa then came into the kitchen and revealed that she had seen Sophie making the mess earlier that day.
Can we infer that "Sophie is usually more responsible than Olivia."? Yes, no, or maybe?
