Question

the passage below describes an experiment. jared was a chef’s assistant in an italian restaurant. one of his coworkers told him that adding salt to water would cause the spaghetti to cook faster. jared gathered six pots that were the same size. he filled each pot with the same amount of pure water. he added one tablespoon of salt to each of the first two pots and two tablespoons of salt to the next two pots. he did not add salt to the other two pots. then jared boiled spaghetti in each pot. he checked how firm the spaghetti was after five minutes of boiling. in this experiment, which were part of a control group? the pots with water and one tablespoon of salt the pots with pure water

Explanation:

In an experiment, the control group is the group where the independent variable (here, the amount of salt) is not manipulated, so it serves as a baseline for comparison. Jared didn't add salt to the pots with pure water, while he varied the salt amount in other pots. So the pots with pure water (no salt added) are the control group as they represent the normal condition without the experimental treatment (salt addition) to compare the effect of salt on cooking spaghetti. The pots with one tablespoon of salt are part of the experimental group with a specific salt amount, not the control.

Answer:

the pots with pure water
