Comprehension:
Read the following passage and answer the questions that follow.
A radical new surgery procedure, laughed at not long ago, is holding out fresh hope for patients of cardiac myopathy, or enlargement of the heart. The technique, now in India, allows patients to go home two weeks after the operation, to lead a near-normal sedentary life. Cardiac myopathy is a condition that has a variety of causative factors. An attack from one of the 20 identified viruses, parasite infection, long-term alcohol abuse and blood pressure could bring it on, and in rare cases, it could follow child birth and is even known to run in families. The condition is marked by an increase in the size of the heart's chambers and a decrease in the efficiency of pumping.
Cardiac myopathy is a condition characterized by ________________.
- A.
A constriction of the heart
- B.
Reduction in the size of lungs
- C.
Restricted air-flow to the lungs
- D.
An enlargement of the heart

Show answer & explanation
Correct answer: D
Answer: An enlargement of the heart.
Explanation: The passage defines cardiac myopathy directly and describes its main features.
Supporting evidence: The passage calls cardiac myopathy "enlargement of the heart" and says it is marked by "an increase in the size of the heart's chambers and a decrease in the efficiency of pumping."
Therefore, the condition is characterized by enlargement of the heart rather than by any change in the lungs or airflow.
Why the other choices are incorrect:
A constriction of the heart: This contradicts the description of an increase in heart size.
Reduction in the size of lungs: The passage discusses the heart, not the lungs, so this is irrelevant.
Restricted air-flow to the lungs: This describes a respiratory problem, but the passage focuses on enlargement and decreased pumping efficiency of the heart.
