Question

Celiac disease results from an inability of the digestive tract, specifically the small intestine, to absorb gluten, a protein found in wheat, barley, and certain other grains. The body's immune system attacks the gluten as if the protein were a harmful pathogen, often resulting in serious damage to the intestinal lining. People who suffer from celiac disease must eliminate gluten from their diets. Symptoms of the disease include abdominal cramps, bloating, and anemia.

If the statements above are true, which of the following assertions can be made on the basis of them?

• A. Anyone who suffers from celiac disease will experience anemia.
• B. Eliminating gluten from one's diet will cure celiac disease.
• C. People experiencing abdominal cramps, bloating, and anemia have celiac disease.
• D. Gluten is found only in grains.
• E. The human body cannot always recognize harmless substances.

Answer 1

The correct option is E The human body cannot always recognize harmless substances.

The human body cannot always recognize harmless substances.
"The body's immune system attacks the gluten as if the protein were a harmful pathogen" - as if means that gluten is not harmful or harmless. Body attacked it means body could not recognize it as harmless.
