A science research group is testing a new type of plant food. One trial is conducted in a controlled experiment. The data from the trial show that the plant that received the new food grew faster than the control plant. The group announces that the new plant food makes plants grow faster. What is the main weakness in this scientific claim? The claim is not based on a controlled experiment. The claim is not based on data. The claim is not made by scientific researchers. The claim is not based on evidence from multiple trials.
