Answer :1). Thoroughness measure, such as coverage of code, functionality or risk. 2).Estimates of defects density or reliablity measures.
3).Residual risk such as defects not fixed or lack of test coverage in certain areas.

27.Question : What helps in monitoring the test progress?
Answer :1). Percentage of test case execution 2).Percentage of work done in test environment preparation
3).Defect information e.g. defect density, defect found and fixed.

28.Question :The selection of test approach should consider the context:
