Explanation:

• The text states "Carbohydrate molecules are made of carbon, hydrogen, and oxygen", so the first statement is true.
• It also says "Carbohydrates are the primary source of energy for all living things", confirming the second statement.
• Additionally, "Carbohydrates can also be used to form cell structures" implies some organisms use them for structural support (third statement).
• However, the text only lists some sources of carbohydrates (potatoes, pasta, etc.), not all foods, so the fourth statement is false.

Answer:

• Carbohydrates are made of carbon, hydrogen, and oxygen.
• Living things use carbohydrates for energy.
• Some organisms use carbohydrates for structural support.
