Modifier error(E) Making a successful debut last summer, three years after researchers started testing the prototypes[/color], objects weighing 65 pounds are picked up and maneuvered with ease by robotic exoskeletons that are thus in increasing demand.
Modifier error(C) Making a successful debut three years after researchers started testing the prototypes last summer, robotic exoskeletons allow workers to pick up and maneuver objects weighing 65 pounds with ease and thus are in increasing demand.
(D)
Making a successful debut last summer, three years after researchers started testing the prototypes, robotic exoskeletons allow workers to pick up and maneuver objects weighing 65 pounds with ease and thus are in increasing demand.
D is better than C, last year is properly modified in D. In C it creates confusion.
IMO D
