Read the excerpt from "Healthy Eating."

Fourteen years ago, Juanita Ferguson, 55, had a kidney transplant. So she watched what she ate and always included fruits and vegetables in her diet.

But it was the finer points that Ferguson, a supervisor in the respiratory care department at Baptist, was missing. She bought honey wheat bread, not realizing that at her age she needed much more fiber. She was unaware of her carb intake. And she had no idea that on weekends, when she was completing chores and running errands, forgetting to eat was causing problems.

The author suggests in this excerpt that-
a

it is important for people to be informed about what their bodies need.
b

older people make poor food choices that cause life-threatening illnesses.
c

older people know less than others about what they should be eating.
d

it is usually easy for people to figure out what types of food to eat.
