- A) He beat the world chess champion
- B) He predicted the 3D shape of millions of proteins, a 50-year-old puzzle
- C) He drove a car without an accident for a year
- D) He composed a symphony played at the opera

### Question 4
On the car autonomy scale (levels 1 to 5), what does **level 5** mean?

- A) The car only helps to keep the speed
- B) The car drives alone on the highway only
- C) The car drives alone everywhere, all the time, without any humans — this level does not yet exist
- D) The car is traveling at a maximum of 5 km/h

### Question 5
How do Waze and Google Maps know when there is a traffic jam?

- A) Employees monitor all roads with binoculars
- B) Millions of phones send their speed in real time, and AI infers traffic
- C) They guess according to the time of day only
- D) Cars honk into a special microphone

### Question 6
What does AI enable in so-called “precision” agriculture?

- A) Replace all farmers with robots
- B) Make plants grow twice as fast using waves
- C) Identify exactly the areas of the field that need water or treatment, using drones and image analysis
- D) Control the weather so that it rains at the right time

### Question 7
How does your bank detect a fraudulent payment in milliseconds?

- A) An employee verifies each payment by hand
- B) It blocks all payments made at night
- C) An AI has learned YOUR payment habits and identifies transactions that do not resemble you
- D) She calls the store to check

### Question 8
How does AI help fight deforestation?

- A) She plants trees with robotic arms
- B) It continuously analyzes satellite images of forests and alerts almost in real time when trees disappear
- C) It prohibits the purchase of wooden furniture
- D) It makes the wood harder to cut

### Question 9
Which of these tasks is the MOST difficult for an AI?

- A) Analyze 10,000 radios in one day without tiring
- B) Spot an abnormal payment among millions
- C) Consoling a patient who has just heard bad news
- D) Recommend a series based on your history

### Question 10
Which sentence best summarizes the central message of this session?- A) AI will replace all professions within 10 years
- B) The AI is unbeatable on the repetitive, the massive and the fast; the human remains unbeatable on context, emotion and the unprecedented
- C) AI is useless in real life, it's marketing
- D) AI only works in research laboratories

## ✅ Corrected commented

**1. B** — This is machine learning seen in session 2, applied to medicine: examples labeled by experts (“tumor” / “no tumor”), and the AI ​​learns the patterns. Neither written explanation (A), nor reading books (C), nor magic without data (D).

**2. C** — The golden rule of the session: the AI ​​**points out** suspicious areas, the doctor **decides**. AI is a tireless second glance, not a decision maker. Medical responsibility remains human — and that is very good.

**3. B** — AlphaFold (DeepMind) has nearly solved the problem of protein folding and predicted the shape of more than 200 million proteins — accelerating drug research worldwide. Its creators received the 2024 Nobel Prize in Chemistry. (Described Deep Blue/AlphaGo, other AI milestones.)

**4. C** — Level 5 = total autonomy, everywhere, in all weather, without steering wheel if you want. **It doesn't exist yet.** Current "autopilots" are mostly level 2, and some robotaxis reach level 4 in limited areas. ⚠

**5. B** — Each phone that uses the app is an anonymized sensor: position + speed. Millions of sensors → AI sees slowdowns live and recalculates routes. The collective at the service of everyone.

**6. C** — Drones + image analysis = knowing exactly WHERE to act. Result: less water, fewer pesticides, more yield. The AI ​​does not accelerate the shoot (B) or control the weather (D) — it makes the action **precise**.

**7. C** — Fraud detection is one of the oldest applications of AI: the system learns your habits (amounts, locations, times) and spots anomalies instantly. Impossible to do by hand (A) on the scale of millions of transactions.

**8. B** — Services like Global Forest Watch compare satellite images continuously. Before AI, we discovered deforestation months later; now the alert goes away in a few days. Planetary-scale surveillance is exactly the type of “massive” task where AI excels.

**9. C** — A, B and D are repetitive and massive tasks: the realm of AI. Consoling requires **real** empathy, presence, understanding of a personal story: the human kingdom. An AI can simulate kind words, it doesn't feel anything.

**10. B** — THE sentence of the session. Neither total replacement (A), nor useless gadget (C): AI is a formidable **assistant**. The best teams — in the hospital, in the fields, in the classroom — combine the computational power of AI and human judgment.

### Indicative scale
- **9-10 correct answers:** 🏆 World tour validated — you see AI everywhere (and it's justified)!
- **7-8:** 💪 Very solid. Reread the autonomy levels of cars and the golden rule.
- **5-6:** 📚 The main thing is there. Take another look at the interactive map on the web page.
- **< 5:** 🔄 Go back to the session guide — and above all, do exercise 3 again (“Is it AI or not?”): it’s the best training.
