Answer 2

The given sentence can be written using a modal auxiliary denoting compulsion: You must start a waste segregation system in your building, school or neighbourhood.

• Modals are the words that are used to express the possibility, suggestion, obligation, capabilities, etc. For example, can, should, ought to, must, might, may, shall, will, and have to are some of the modal auxiliaries.
• Must and have to are used to denote compulsion. For example, I have to buy fruits. So, this sentence denotes the necessity of buying fruits.
• So, the given sentence can also be written using 'have to'. For example, You have to start a waste segregation system in your building, school or neighbourhood.
