Question

the passage below describes a process of scientific inquiry. select the part of the passage that describes revising the hypothesis.
hint: to revise the hypothesis, you use the results of the investigation to come up with a new explanation.
watering flowers
james grows flowers in his garden. he read that flowers grow better in slightly acidic soil, so he wondered if adding vinegar would help his flowers grow. he predicted that since vinegar is acidic, mixing it with the water when watering his flowers would make them grow larger. james planted identical flowers in two pots. for one month he watered one pot with water and the other with a mixture of water and vinegar. he found that the flowers he watered with water alone grew well, while those watered with vinegar and water wilted. james concluded that the vinegar damaged the flowers it came into direct contact with. he then predicted that lowering the ph of the soil by adding aluminum sulfate would improve the growth of his flowers.

Explanation:

The initial hypothesis was that mixing vinegar with water would make flowers grow larger. After the experiment showed vinegar - water mix made flowers wilt, James formed a new prediction about using aluminum sulfate to lower soil pH for better flower growth. This new prediction is based on the results of the previous investigation and is a revised hypothesis.

Answer:

He then predicted that lowering the pH of the soil by adding aluminum sulfate would improve the growth of his flowers.
