IV. Read then answer the question:

Paper is one of the materials that can be easily recycled. Recucled paper is paper that was made from paper and paper products that already been used and recovered. Firstly, we need to collect the paper materials from the collection points such as paper stores, trash bins or paper scrap yards. Then they are measured, graded for quality and hauled to recycling paper mill facilities. After that, the papers are sorted by assessing the materials or their surface treatment and structure. Once orting is finished, we need to shred the papers to break down them into small bits ad than mix with water and chemicals to turn them into slurry substance. Then, this substance will be taken through a comprehensive filtering process to get rid of any impurities like tape, glue or strings. And finally, it's paper recycling. The cleaned puld is blended with new production materials and put on a flat conveyer belt and heated surfaces to become solid. The paper sheets are then rolled. trimmed and made into many other products such as newspaper printing, wrapping papers or printing papers.

Read the passage below and decide whether the statements are TRUE or FALSE?

Paper can be recycled by reducing it to pulp and combine it with pulp from newly harvested wood. As the recycling process causes the paper fibers to breakdown, each time paper is recycled its quality decreases. This means that either a higher percentage of new fibers must be added, or the paper down cycled into lower quality products. Any writing or coloration of the paper must first be removed by deinking, which also removes fillers, clays, and fiber fragments. Almost all paper can be recycled today, but some types are harder to recycle than others. Papers coated with plastic or alumium foil, and papers that are waxed, pasted, or gummed are usually not recycled because the process is too expensive. Gift wrap paper also cannot be recycled due to its low quality.
