Question

A student conducted an experiment to test whether talking to plants would help them to grow faster. The student talked to one group of plants and hand watered them. The student did not talk to the other group of plants and used sprinklers. After three weeks, the plants that were spoken to showed much more growth than the plants that were not. Based on the results of this experiment, which is the best conclusion? Talking to plants may or may not help plants grow faster because three weeks is not enough time to tell. Talking to plants may or may not help plants grow faster because the amount of water given was likely different for each group. Talking to plants does not help plants grow faster because the experiment did not involve enough groups of plants to determine this. Talking to plants does help plants grow faster because those plants showed more growth. Unmark this question

Answer 1

I'd say the answer would be the second one. Since two things happened at once, you cannot rule out one or another until you know for sure
