Was Jim a successful packer? Give reason to prove your point.

Are you referring to Harris? Jerome states that:

"Then Harris packed the strawberry jam on top of a tomato and squashed it, and they had to pick out the tomato with a teaspoon."

No,because he smashed tomato by putting a strawberry jam jar on it. Then he had to pick up with a teaspoon. He made a lot of mess around. He unpacks and repacks as one thing or the other keeps on getting left out.
