A long-lasting dry cough, a hoarse voice and loss of weight are the symptoms of which disease?
Think it through first, then pick an option.
- a lung cancer
- b asthma
- c bronchitis
- d tuberculosis
Answer and explanation
Correct answer: a lung cancer
A hoarse voice appears only in the book's lung cancer list; the dry cough and weight loss are in that list too.
Why the other options are wrong
- b asthma: "asthma" does not fit here. A hoarse voice appears only in the book's lung cancer list; the dry cough and weight loss are in that list too.
- c bronchitis: "bronchitis" does not fit here. A hoarse voice appears only in the book's lung cancer list; the dry cough and weight loss are in that list too.
- d tuberculosis: "tuberculosis" does not fit here. A hoarse voice appears only in the book's lung cancer list; the dry cough and weight loss are in that list too.
