Final answer:
The information provided does not contain enough details to determine the two jobs Marty found on the bulletin board; the text or source describing Marty's search must be analyzed for an accurate answer.
Step-by-step explanation:
Please note that the given information does not contain sufficient details to answer the specific question about Marty searching the bulletin board for job ads. Since the background provided discusses scenarios such as a construction worker being laid off and requirements in job ads, without a direct reference to the job listings Marty found, it is not possible to accurately determine which two jobs were listed.
For a meaningful answer, the text or source where Marty's situation is described needs to be examined. Only then can the correct job listings he found be identified.
