Recently in a small city, building contractors lobbied the city munipality to pass a law requiring all people working on residential dwellings be licensed. Why would the contractors lobby for this requirement?a.to reduce the cost of building dwellingsb.There is no good explanation for this type of lobbying.c.to guarantee that work on dwellings is of high qualityd.to create a legal barrier to entry

The contractors would lobby for this requirement to guarantee that work on dwellings is of high quality and to create a legal barrier to entry.

When all workers are required to be licensed, it ensures that they have met certain standards of competence and knowledge in their field. This can help to ensure that the work done on residential dwellings is of a high quality, which can protect homeowners and potentially reduce liability for contractors.

Additionally, requiring a license can create a legal barrier to entry. This means that it can prevent people who are not licensed from legally working in the field. This can reduce competition for the contractors, potentially allowing them to charge higher prices for their work.

The contractors would lobby for this requirement for a couple of reasons:

1. To guarantee that work on dwellings is of high quality: Licensing ensures that all workers have met certain standards of competence and knowledge in their field. This can help to ensure that all work done on residential dwellings is of a high quality, which can help to protect the reputation of the building industry in the city.

2. To create a legal barrier to entry: By requiring all workers to be licensed, it can make it more difficult for new workers to enter the field. This can help to reduce competition for the existing contractors, potentially allowing them to charge higher prices for their services.

So, the correct answers are c. to guarantee that work on dwellings is of high quality and d. to create a legal barrier to entry.
