The path of food through the bodyMouthEsophagusStomachSmall intestineLarge intestineA diagram drawn for this example.
According to the flowchart, which step comes immediately after the stomach?
  1. A flowchart is read from the top, following the arrows in the direction they point.
  2. Find the box that says Stomach.
  3. Follow the one arrow leaving it, down to the next box: Small intestine.
  4. The large intestine also comes after the stomach, but it is two arrows away. “Immediately after” means the very next box.

Answer: Small intestine

Salt water is more than one substance, and it is the same all the way through. Following the flowchart, where does it end up?
  1. Start at the top and answer each question in turn. You follow only one branch.
  2. Is it made of only one substance? No: salt water is salt and water. Take the “No” arrow, to the right.
  3. Is it the same all the way through? Yes: once the salt dissolves, every drop is equally salty. Take the “Yes” arrow.
  4. That arrow ends at Solution.
  5. Reading the other branch by mistake, the one for single substances, would give compound or element. Answer the top question first; it decides the side.

Answer: Solution
