Question

the passage below describes a process of scientific inquiry. select the part of the passage that describes identifying a question. after walking by some rusted cars parked in the street, tessa wondered whether all metals are equally susceptible to corrosion. tessa could not recall ever seeing rusted aluminum objects, and she reasoned that aluminum must be less susceptible to corrosion than other metals, like iron. tessa gathered some iron nails and aluminum foil. she prepared a saline solution by mixing salt into water. she then poured equal amounts of the solution into four separate cups. next, she placed an iron nail in two of the cups and a piece of aluminum foil in the other two. by the end of the week, tessa noticed that the iron nails had rusted significantly, while the aluminum foil showed almost no signs of corrosion. she determined that iron is highly susceptible to corrosion in saline conditions, while aluminum is much more resistant

Explanation:

The part where Tessa wonders about the susceptibility of metals to corrosion is the identification of a question. This is the starting - point of her scientific inquiry.

Answer:

After walking by some rusted cars parked in the street, Tessa wondered whether all metals are equally susceptible to corrosion.
