The technique, now in Pakistan, 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 hereditary.
Correct answer: B. Probably true
- A. Definitely true
- B. Probably true
- C. Data inadequate
- D. Probably false
- E. Definitely false
Explanation
The correct answer is 'Probably true' because the passage states that cardiac myopathy is 'even known to run in families,' suggesting a potential hereditary link. However, it does not provide definitive proof, which is why 'probably true' is more fitting than 'definitely true.' Other options such as 'Data inadequate' and 'Probably false' are less appropriate because the passage does provide some evidence of a hereditary component. 'Definitely false' is incorrect as it contradicts the information given in the passage.
