Wie baut der Drucker das Bauteil auf?
A workshop sends a digital design to a 3D printer. The printer builds a replacement part from plastic.
- By cutting the shape from one solid block.
- By pouring plastic into a ready-made mold.
- By adding material one layer at a time.
Show solution
- By adding material one layer at a time.
Durch eine Änderung des digitalen Designs lässt sich das nächste Bauteil verändern, ohne eine neue Form herzustellen.

How could this help in a meeting room?
A glass wall switches from clear to cloudy when an electric current is turned on or off. Light still passes through, but people cannot see clearly through it.
- It could block all daylight so people can watch a video.
- It could give privacy without making the room dark.
- It could give people a clearer view into the room.
Notice that light can still enter.
Show solution
- It could give privacy without making the room dark.
This kind of smart glass spreads light in different directions instead of blocking it completely.

Was ist hier der Hauptvorteil der Drohne?
A clinic sends blood samples to a lab by delivery drone. Floodwater has blocked the road between them.
- It can reach the lab without using the blocked road.
- It can test the blood samples during the flight.
- It keeps the samples safe at any temperature.
Denk eher an den Transport als an die Arbeit des Labors.
Show solution
- It can reach the lab without using the blocked road.

Why do these conditions make it easier for a train to run without a driver?
Some metro trains run without a driver. They follow fixed tracks, and access to those tracks is controlled.
- The train can leave the tracks to avoid delays.
- The train no longer needs any safety monitoring.
- The train faces fewer unexpected situations than a car on public roads.
Show solution
- The train faces fewer unexpected situations than a car on public roads.
Road vehicles must also deal with pedestrians and traffic coming from many directions.

Warum könnte ein Arzt diese Kamerakapsel verwenden?
A patient swallows a small capsule with a camera inside. It travels through the digestive system and sends pictures to a recorder.
- To remove damaged tissue without surgery.
- To view parts of the intestine that a larger camera tube cannot easily reach.
- To collect blood samples directly from inside the intestine.
Überlege, was eine Kamera tun kann, ohne etwas zu schneiden oder zu sammeln.
Show solution
- To view parts of the intestine that a larger camera tube cannot easily reach.
Eine Kamerakapsel macht Bilder, kann aber im Gegensatz zu manchen anderen medizinischen Instrumenten keine Gewebeproben entnehmen.

11. Wähle die richtige Antwort aus.
Wie unterscheidet sich das davon, Töne einfach lauter zu machen?
A cochlear implant collects sound with a microphone. It changes sound into electrical signals that stimulate the hearing nerve.
- It sends sound information to the hearing nerve through electrical signals.
- It repairs the ear so it works like an undamaged ear.
- It allows hearing without a working hearing nerve.
Show solution
- It sends sound information to the hearing nerve through electrical signals.
Menschen brauchen in der Regel Übung, um die neuen Tonsignale eines Implantats zu verstehen.

Wie steuert die Person diese künstliche Hand?
Sensors detect activity in a person's remaining arm muscles. The artificial hand uses those signals to open and close its fingers.
- By giving spoken commands to the fingers.
- By letting the hand read thoughts directly from the brain.
- By tightening muscles in the remaining part of the arm.
Show solution
- By tightening muscles in the remaining part of the arm.
Die Sensoren erfassen die Muskelaktivität; eine Batterie liefert die Energie, die die Hand bewegt.

Who decides how the tools move during this operation?
During robot-assisted surgery, a surgeon sits at the controls. The surgeon's hand movements guide small tools inside the patient's body.
- The robot, without a person's input.
- The surgeon using the controls.
- A program replaying an earlier operation.
Show solution
- The surgeon using the controls.
The robot helps make precise movements, but it does not replace the surgeon's decisions.

What should a user understand about this technology?
In some rehabilitation centers, people use powered frames around their legs. Motors help them practice standing and walking with trained staff.
- It provides movement support, not a guaranteed cure.
- It repairs damaged nerves as soon as it turns on.
- It allows safe walking immediately without training or support.
Physical help and medical recovery are not the same thing.
Show solution
- It provides movement support, not a guaranteed cure.
A powered exoskeleton supports the body from the outside. Helping someone move does not necessarily fix the cause of their condition.

How does this landing method affect fuel use during launch?
Some rocket boosters return to Earth and land upright using their engines. They must keep some fuel for the return trip so they can land safely and be used again.
- All the fuel can be burned on the way up.
- No fuel is needed until the booster starts returning.
- Some fuel must be saved instead of being used on the way up.
The engines have work to do during both parts of the journey.
Show solution
- Some fuel must be saved instead of being used on the way up.
Reusing boosters can save expensive rocket parts, but landing requires fuel, and each booster needs careful checks afterward.
