The term 'examined thoroughly' can be summarized by two six-letter words: 'VETTED' and 'PROBED'. To 'VET' something means to examine it carefully, often in order to assess its suitability for a particular purpose. To 'PROBE' something means to investigate it in detail, often in order to uncover information or gain an understanding of it. Therefore, the term 'examined thoroughly' implies that something has been carefully assessed and investigated in detail.
