=VLOOKUP(SMALL(I8:I14,1),I8:J14,2,)
=VLOOKUP(SMALL(I8:I14,1),I8:J14,2,0)
=VLOOKUP(SMALL(I8:I14,1),I8:J14,2,FALSE)
All three are equivalent and return the same result - MARK. Any will work.

I used a bad verbiage saying "taking out the final argument", I meant remove the value after the comma or use 0 as NBVC suggested. Removing the comma too turns the default TRUE on and it stops working.
