Answer:
Plastics are large organic molecules called polymers.
Explanation:
Plastics can be defined as materials that can be shaped when soft and then hardened to keep their shape. They are synthetic (artificially made) or semi-synthetic, derived from materials found in nature, such as natural gas, oil, coal, minerals, and plants.
As they are derived from natural, organic materials, plastics also consist of organic molecules. Their molecules are very large and long and consist of many repeating subunits. Materials with this type of structure are called polymers.
This is why the second option is the correct one.
The projectors project perpendicularly polarized light with respect to each other and the screen maintains this polarisation. All that is needed are simple 3D glasses with polarised frames that make sure that the image made from the right camera coming from the right projector goes into our right eye and the light from the left projector goes into the left eye and our brain puts it all together to give us stereoscopic 3D vision of a 2D screen
