The correct Answer is:
To solve the question of what should be added to plastics to change them from hard to soft and readily workable into new objects, we can analyze the given options step by step. ### Step-by-Step Solution: 1. **Understanding the Question**: We need to identify a substance that can transform hard plastics into a softer, more malleable form. 2. **Analyzing the Options**: - **Catalyst**: Catalysts are substances that increase the rate of a chemical reaction without being consumed in the process. They do not change the physical properties of plastics, so this option is not correct. - **Telomeres**: Telomeres are repetitive nucleotide sequences at the ends of chromosomes and are not related to the properties of plastics. Therefore, this option is also not correct. - **Plasticizers**: Plasticizers are additives used to increase the plasticity or fluidity of a material. They are specifically used to convert rigid plastics (like PVC) into softer, more flexible forms. This option fits the requirement of the question. - **Vulcanizers**: Vulcanizers are substances used to improve the strength and elasticity of rubber. They do not apply to the transformation of hard plastics into softer forms, making this option incorrect. 3. **Conclusion**: Based on the analysis, the correct answer is **Plasticizers**. They are the additives that can make hard plastics soft and workable. ### Final Answer: **Plasticizers**
