PT53.S4.Q27 - Controlling agricultural pests

slxyzvvv-1

Hi guys, I've been struggling with this question. I chose E. I know that JY explains this by saying we don't know if this use of parathion happens in real world or is it just in our experiment. But doesn't the last paragraph explicitly say that the experiment results are "similar in field planting of strawberries"? Doesn't this show that it indeed happens in real world, that some people indeed used parathion to eliminate T and eventually caused C to reach a damaging level?
