Answer:
-Lara works as a Plant Scientist and Jon works as a Farmworker.
Step-by-step explanation:
Lara works by producing plants that are altered centrally so that they become more nutritious to animals. This is technology work, so she is a plant scientist. On the other hand, Jon seeks to feed the cattle with the best nutrient he can find. That is why he seeks the plants produced by Lara. Thus, we conclude that Jon is a farm worker. This is the person responsible for taking care of the animals and plants on a farm.
