The correct answer is: Job enlargement
Rationale: Eva's new tasks are of the same skill level and responsibility as her original task, so her job has been horizontally enlarged rather than vertically enlarged (which would be job enrichment). If she had gone from just packing one shift, to just stamping on the next shift (and so on), this would have been job rotation.
Job evaluation is an irrelevant distractor: job evaluation is a method of measuring the value of jobs for salary/wage setting and nothing to do with job design.
Pitfalls: Any area like this where students frequently confuse similar terminology is ripe for examining. Read, think and check your answers carefully, to avoid careless errors!
