Answer:
The previous job of Heating, Ventilation, and Air-Conditioning HVAC system technician best described Grayson's situation.
Step-by-step explanation:
The previous job of Heating, Ventilation, and Air-Conditioning HVAC system technician best described Grayson's situation because Garyson can not undertake such job ab-initio if he has not got the requistite skills and competencies to handle such a highly technical job. He has got some mastery to have delivered on the job while on the employment. He was not laid-off for lack of skills amd competencies to handle the jobs but for economic downturn.
Howerver, the story line had it that he got employed as a stock employee in Home Depot for lack of the HVAC job not because it was a better job or his choice job but as a make-shift. Rather than remained unemployed, he took the available job pending when he will get a HVAC job or be recalled to his former job when the economy improves.
