the passage below describes a process of scientific inquiry. select the part of the passage that describes identifying a question. hint: to identify a question, you pose a question about a scientific problem. pots of hydrangea flowers marvin had a hydrangea plant that produced blue flowers. he moved his plant from a pot to a planter bed in his yard, and the next time the plant flowered, the flowers were pink! he tested the soils and found that the ph, or acidity, differed between the pot and the planter bed. this led him to wonder if soil ph could affect the color of hydrangea flowers. marvin filled five pots with soil with a ph of 5.0 and another five with soil with a ph of 6.5. he planted six hydrangea seeds in each pot. he found that the plants grown in ph 6.5 soil bloomed pink, while those grown in ph 5.0 soil bloomed blue. marvin deduced that soil ph influences hydrangea flower color. he shared his results on his favorite gardening blog.

Explanation:

The part where Marvin wonders "if soil pH could affect the color of hydrangea flowers" is him posing a question about a scientific problem (the change in flower color related to soil - location change and pH difference).

Answer:

This led him to wonder if soil pH could affect the color of hydrangea flowers.
