Is this multiple choice? If so, can you show it so I can help?
The oldest rocks will be found at the Mariana Trench.
Explanation:
There is a general rule when it comes to where the oldest rock of a plate is located and where the youngest rock is located. That is based on where there are divergent boundaries and where there are convergent boundaries. The places where there are divergent boundaries are the places where new crust is formed, thus the closest a place is to the boundary the younger the rock is. The places where there are convergent boundaries are the places that are the furthest away from the places where the new rock is formed, so they are where the oldest ones are.
In this case, we have the Pacific plate. The East Pacific Rise is a place where new crust forms, meaning that the youngest crust is there. The oldest crust will be located in the trenches that are the furthest away from it, and that would be the Mariana Trench, which is also the deepest trench in the world.
Other trenches of the Pacific that would be among the candidates for some of the oldest rocks are:
- Kuril Trench
- Japan Trench
- Kermadec-Tonga Trench

The correct answer is - ozone.
The ozone is essentially three molecules of oxygen, or O³. This gas is crucial for the life on the Earth because it is the one that manages to filter out big portion of the UV radiation from the Sun which is extremely harmful if its too strong, as it will contribute to the dying out of pretty much every living organism.
While the ozone layer in the stratosphere is very useful, the ozone in the lower parts of the troposphere is actually considered as pollutant. The reason why it is considered as pollutant is because it is very harmful if inhaled, and it also heavily damages the plants.
