Final answer:
The bird will not be able to make the container leave the ground and sustain it in flight due to the lack of necessary lift and the confinement of the airtight container.
Step-by-step explanation:
The flying bird will not be able to make the container leave the ground and sustain it in flight. In order for an object to fly, it needs to generate enough lift to overcome the force of gravity. In this case, the bird is trapped in an airtight container, which means it cannot generate the necessary lift by flapping its wings against the ceiling.
Additionally, even if the bird could generate enough lift, the airtight container would still be anchored to the ground, preventing it from taking off. The bird's flapping wings would just push against the ceiling, causing it to exert force downwards, but not enough to overcome the weight of the container and the bird itself.
In summary, the bird will not be able to make the container leave the ground and sustain it in flight due to the lack of necessary lift and the confinement of the airtight container.
