Answer:
The correct answer will be option-If students spend more time reading on their own, their ELA grades will increase, because they will have more practice analyzing what they read.
Step-by-step explanation:
A scientific hypothesis is a proposed idea or an "educated guess" based on the prior research and predictions which can be tested through the experiments.
A scientific hypothesis can lead us to reach a conclusion related to the scientific issue which can lead to the formation of another hypothesis.
In the given question, the option which includes the reading and practice can be best explained and lead to another hypothesis as the hypothesis is not based on the personal ideas or opinions but previous research evidence could be found. The hypothesis experiments can be performed.
Thus, the selected option is the correct answer.
