Answer: Seth's meticulous lab work makes him better suited for Diagnostics than for Therapeutic Services
Step-by-step explanation:
Since Seth is meticulous in his laboratory work, he'll fit in more at Diagnostics than for Therapeutic Services. One who is involved in diagnostic will be involved in different laboratory test, blood test etc and needs to be very careful while doing these tests.
His friendly nature would have made him more suited for therapeutic services as he'll relate more with customers and counsel them as well.
