Final answer:
A contractor may reject a project if the risks are too large, but it is not a decision taken lightly.
Step-by-step explanation:
A contractor may decide to reject a project if the project risks are too large.
For example, if the contractor believes that the project poses significant safety hazards or if it is financially risky and may result in significant losses, they may choose to reject the project.
However, it is important to note that rejecting a project is not a decision taken lightly as it can have consequences for the contractor's reputation and future opportunities.
