A school rule says: "If a student’s mark is greater than 50, the student has passed the exam, else the student has failed." Which statement correctly applies this decision-making rule to a mark of 48?
The student has passed because 48 is greater than 50

The student has passed because 48 is close to 50
The student has failed only if the mark is below 40

Recall: Which statement best defines Artificial Intelligence (AI) as described in the lesson?
AI is only about building physical machines that look like humans.
AI refers to computer technology that can perform complex tasks such as logical reasoning, decision-making, and problem-solving.
AI is a tool used only for watching videos online.
AI is the same as simple computer programs that follow fixed steps.
Skill/Concept: Choose the example that shows an AI application from daily life.
A screwdriver used to tighten bolts.
YouTube recommending videos you might like.
A paper map folded in a backpack.
A regular alarm clock with no smart features.
Strategic Thinking: A company wants machines that can copy human or animal actions to help in a factory. Based on the lesson, which technology should they focus on first, and why?
Artificial Intelligence, because it builds the physical robots that move.
Robotics, because it combines computer science and engineering to produce robots that replicate actions.
Social media, because it teaches robots how to chat.
Healthcare, because it is a field that uses AI for recommending medicines.
Recall: Which field listed in the lesson is a place where AI is widely used?
